correct_option:
<div class="correct-answer">
The correct answer is:
<span class="option-value">Two sperms and a vegetative cell</span> </div>

answer:
<div class="solution"><p>In Angiosperms, pollen grain is the first male gametophyte. </p><p><strong>Microspore divides mitotically forming two cells.</strong><br/><strong>1. Vegetative cell:</strong> Bigger in size having abundant food reserve and large irregularly shaped nucleus.<br/><strong>2. Generative cell:</strong> Small and floats in the cytoplasm of the vegetative cell. It is spindle-shaped with dense cytoplasm and nucleus.<br/>Shedding of pollen grains takes place at this two-celled stage in 60 % of angiosperms. In rest, the generative cell divides to form the male gametes (sperms) and pollen is shed at the three-celled stage.</p></div>

answer:
<div class="solution"><p>The mucous membranes lining the digestive, respiratory and urogenital systems have a combined surface area of about 400 m<sup>2</sup>, which is equal to the size of a standard basketball court.  They are the major sites of entry for most pathogens. These vulnerable membrane surfaces are defended by a group of organized lymphoid tissues collectively known as mucosal-associated lymphoid tissue (MALT). It constitutes about 50 per cent of the lymphoid tissue in human body.</p></div>

answer:
<div class="solution">The leaves in Pteridophyta are small (microphylls) as in <em>Selaginella </em>or large (macrophylls) as in ferns. The sporophytes bear sporangia that are subtended by leaf-like appendages called sporophylls. In some cases, sporophylls may form distinct compact structures called strobili or cones. The sporangia produce spores by meiosis in spore mother cells. The spores germinate to give rise to inconspicuous, small but multicellular, free-living, mostly photosynthetic thalloid gametophytes called prothallus.<br/>Heterospory is observed as both small and large spores are produced.</div>

The correct answer is:
<span class="option-value">All the above.</span> </div>

answer:
<div class="solution">A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. Though its contribution is very less in comparison to stomata, it is much needed for the plants.</div>

answer:
<div class="solution">The head of the cockroach is hypognathous i.e. the lower jaw is longer than the upper jaw. Head is triangular in shape and lies anteriorly at right angles to the longitudinal body axis. It is formed by the fusion of six segments and shows great mobility in all directions due to the flexible neck. The head capsule bears a pair of compound eyes. A pair of thread-like antennae arise from membranous sockets lying in front of eyes. Antennae have sensory receptors that help in monitoring the environment. Anterior end of the head bears appendages forming biting and chewing type of mouth parts.</div>

answer:
<div class="solution">Collenchyma, part of the ground tissue, is a simple living tissue found in plants. The cell wall of collenchyma tissue cells is thickened at corner due to higher deposition of cellulose, pectin and hemicellulose. The cells are generally spherical or polygonal in shape. This tissue provides mechanical support to the young stem and leaf. The outermost covering of the whole plant body forms the epidermal tissue system that includes the epidermal cells and appendages with stomata. This system basically provides protection to the main plant body. The outermost layer of primary plant body called as epidermis have elongated compactly arranged cells. Stomata structures present in the epidermis help in regulating transpiration and gas exchange. These stomata are made of two guard cells each that encloses the pore. <br/><br/>Meristem are a type of tissue found in such plants which can divide indefinitely. These are generally considered undifferentiated as they can give develop into all other tissues and organs of the plant. The meristematic tissues that appear early in plant life and help in formation of the plant body is called primary meristem. The apical and intercalary meristem are included in it. Meristematic tissue occurring between the mature regions of root and shoots of angiosperms are called secondary meristem.<br/><br/>Parenchyma is a type of simple permanent tissues forming a major component of the tissues of plant. These cells are in various shapes like oval, round, polygonal etc. with a thin cell wall made of cellulose. These cells perform functions like storage, photosynthesis, secretion. <br/><br/>The simple permanent tissue consisting of dead cells without protoplast is called sclerenchyma. These cells are long and narrow with lignified cell wall. The thick-walled, elongated pointed cells form the sclerenchyma fibres and the spherical, oval shaped cell with highly thickened cell wall and narrow cavity form the sclerenchyma sclereids.</div>

answer:
<div class="solution">On the upper surface of the isobilateral leaves of monocots large, bubble-shaped cells are present called bulliform cells. These cells help in rolling leaves to prevent transpiration and loss of water. Guard cells surround the stomatal pore and help in the opening and closing of the stomata. Pores formed by rupture of the epidermal region of root and stem at certain locations which help in aeration is called lenticels. These are commonly seen on the bark after secondary growth. Epidermal cells found around the guard cells are called subsidiary cells. The cells are also referred to as accessory cells.</div>

answer:
<div class="solution">Vascular bundles are components of the vascular tissue system that consist of two main parts i.e.xylem and phloem. In which xylem is called water-conducting tissue and phloem is called food conducting tissue. Xylem was proposed by Nageli in 1858.Xylem composed of several types of cells and out of which some are living and some are dead. The elements of xylem are tracheids, vessel, xylem fiber, and xylem parenchyma. Tracheids are tube-like cells and both the ends of the cells are tapered. Vessels are shorter than tracheids and they have perforations at the end wall through which they are interconnected. Xylem fibers have cells with the lignified secondary cell wall. So they possess cells with highly thickened walls. Xylem parenchyma is living cells with cytoplasm and prominent nucleus. So the correct answer is B.</div>

answer:
<div class="solution">Frank-Hertz's experiment demonstrated the existence of excited states in mercury atoms helping to confirm the quantum theory which predicted that electrons occupied only discrete quantized energy states. The photo-electric experiment demonstrated that photon is the particle of light, which can transfer momentum and energy due to collision. Davidson-Germer's experiment shows the wave nature of electrons.</div>

answer:
<div class="solution">Pituitary hormones gonadotrophins i.e. FSH and LH control menstrual cycle in females. FSH is a follicle-stimulating hormone and its main function is to control the development and maturation of ovarian follicles. LH is luteinizing hormone that causes formation of corpus luteum after ovulation has taken place. Ovarian hormones progesterone and estrogen secreted by corpus luteum also play an important role in the menstrual cycle. Progesterone is also important as it prepares the endometrium for implantation by secreting secretory glands. Estrogen develops secondary sexual characters.</div>

answer:
<div class="solution">Ethanol is a type of alcohol that is a product of the fermentation process. Ethanol is widely consumed as a mix in varying degree of concentration (Wine, beer, whisky). Fermentation is an anaerobic respiratory process where many strains of Saccharomyces are used.<br/><br/>Clostrodium is a microbial source for commercial production of butyric acid.<br/><br/>Secondary metabolites like antibiotics are produced by the microbes which inhibit growth of other microbes. Chloromycetin is a type of antibiotics produced by Streptomyces venezuelae.<br/><br/>Microbes are used a direct source of food as they are rich in protein. Single cell protein denotes dead and dried cells of microbes where each cell is like a source of protein. Chlorella, a type of algae is used as SCP.</div>

The correct answer is:

answer:
<div class="solution">The nitrogen oxides are released into the atmosphere when fossil fuels are burnt and that contributes to the formation of smog and acid rain. <br/><br/>Chlorofluorocarbons (CFCs) are the compounds released into the atmosphere due to the usage of air-conditioning, refrigeration, blowing agents in foams, insulations and packing materials, propellants in aerosol cans and as solvents.<br/><br/>The digestion activity of the methanogenic bacteria, the decomposition of fecal matter in the toilets and rice fields release methane into the environment.<br/><br/>Ozone in the troposphere is the secondary pollutant formed by the photooxidation of the car exhausts pollutants.<br/><br/>Oxygen combines with carbon to form CO<sub>2</sub> and with hydrogen to form water (H<sub>2</sub>O) when fossil fuels are burned.</div>

answer:
<div class="solution">Heartwood does not conduct water or transport it but it is hard and gives plant mechanical support and thus consist of dead elements with lignified walls. Early wood or Spring wood is formed during spring season and known to have wide vessels  and Late wood have narrow vessels and cambium is less active in it. Sapwood is a part of secondary xylem in peripheral region which is lighter in colour.</div>

answer:
<div class="solution">Epithelial tissue is divided into two types: Simple and compound based on number of layers resting on the basement membrane. Simple epithelium has only one layer resting on the basement membrane and such epithelium brings abo transport of substances. This epithelium is further divided into various types depending on the shape of cells. These are as follows. A) Squamous epithelium: This consists of flat cells and is responsible for diffusion of substances. The borders are irregular sometimes to increase the surface area and this is tesallated squamous epithelium. This is seen in the inner lining of blood vessels. B) Cuboidal epithelium: This epithelium consists of cube shaped cells. This is seen in the tubular parts of nephrons and is responsible for absorption and secretion of cells. C) Columnar epithelium: This epithelium consists of tall column like cells and is seen lining the intestine. D) Ciliated epithelium: This is cuboidal or columnar cells with cilia that bring about movement of substances. This is seen in the bronchioles.</div>

answer:
<div class="solution"><p><strong>Chitin:</strong> It is the second most abundant organic substance. In chitin the basic unit is a nitrogen containing glucose derivative known as N-acetyl glucosamine. <strong>The exoskeletons of arthropods and cell wall of fungi have chitin.</strong></p><p><strong>Collagen </strong>is the most abundant animal protein and is the chief component of connective tissue. Proteins are the biopolymers made up of monomeric amino acids joined by <strong>amide linkage or peptide bond.</strong></p><p><strong>Malonate</strong> is the competitive inhibitor of the enzyme s<strong>uccinic dehydrogenase.</strong></p><p><strong>Abrin and ricin</strong> are the toxins produced as <strong>secondary metabolites.</strong></p></div>

answer:
<div class="solution">The four fundamental forces of nature are as follows,<br/>(i) Strong nuclear force which is between nuclear particles like, quarks. Its strength is very high and of the order of 1.<br/>But it's range is very short.<br/>(ii) Weak nuclear force which is also between nuclear particles, however its strength is low and of the order of $10^{-13}$. This force is usually found in radioactive nuclei. It is also a short range force.<br/>(iii) Electromagnetic force which is the force between the electrically charged particles. Its strength is of the order of $10^{-2}$. But its range is very high, upto infinity.<br/>(iv) Gravitational force which is the force of attraction between bodies due to gravity. Its strength is very low and of the order of $10^{-39}$. But it's range is very high upto infinity.<br/>So, the correct sequence of match is $\mathrm{A} \rightarrow$ (ii), $\mathrm{B} \rightarrow$ (iv), $\mathrm{C} \rightarrow$ (i) and $\mathrm{D} \rightarrow$ (iii).</div>

The result of his experiment suggested the non-existance of the ether.<br/>B $\rightarrow$ (iii) The Stern-Gerlach experiment demonstrated that the spatial orientation of angular momentum is quantised. Due to spin motion of electrons, particles have non-zero magnetic moment and hence they are deflected to the magnetic field gradient from a straight path.<br/>C $\rightarrow$ (ii) Davisson - Germer experiment<br/>demonstrates the wave nature of electrons i.e., the existence of de-Broglie matter waves.<br/>$\mathrm{D} \rightarrow$ (i) By studying the tracks of cosmic ray particles in a cloud chamber, Anderson discovered a positively charged particles with a mass seemingly equal to that of an electron, named positron, which suggests the existence of anti- matter.</div>

answer:
<div class="solution">A meristem is a simple tissue made of a group of similar and immature cells (meristematic cells) which can divide and form new cells.<br/>Parenchyma cells having chloroplasts are termed as chlorenchyma. It helps in the manufacture of food (photosynthesis). Storage parenchyma is made of large sized vacuolated cells which are used to store water, mucilage and food,<br/>e.g., Aloe, Opuntia, potato tuber.<br/>Collenchyma gives mechanical strength to young dicot stems, petioles and leaves.<br/>Sclerenchyma is of two types, sclerenchyma fibres and sclereids.<br/>Epidermal tissue system make the outermost covering of plant body. It mainly consists of epidermis and epidermal appendages. Epidermis is made of epidermal cells and stomata.</div>

answer:
<div class="solution">The mode of arrangement of sepals or petals in floral bud with respect to the other members of the same whorl is known as aestivation. The main types of aestivation are valvate, twisted, imbricate and vexillary .When sepals or petals in a whorl just touch one another at the margin, without overlapping, as in Calotropis, it is said to be valvate. If one margin of the appendage overlaps that of the next one and so on as in china rose, lady’s finger and cotton, it is called twisted. If the margins of sepals or petals overlap one another but not in any particular direction as in Cassia and gulmohur, the aestivation is called imbricate. In pea and bean flowers, there are five petals, the largest (standard) overlaps the two lateral petals (wings) which in turn overlap the two smallest anterior petals (keel); this type of aestivation is known as vexillary or papilionaceous.</div>

answer:
<div class="solution">The carbon dioxide assimilation during photosynthesis is of two main types. In those plants in which the first product of carbon dioxide fixation is 3-phosphoglyceric acid (a C<sub>3</sub> acid)is known as the C<sub>3</sub> pathway or Calvin cycle, and those in which the first product is oxaloacetic acid (a C<sub>4</sub> acid) is the C<sub>4</sub> pathway. CAM (Crassulacean Acid Metabolism) pathway is a method of carbon fixation evolved by some plants in dry circumstances where stomata open during the night to take in carbon dioxide to prevent water loss. <em>Kalanchoe</em> belongs to family Crassulaceae and shows the CAM pathway of carbon fixation. <em>Triticum</em> (wheat plant) uses the standard method of Carbon fixation that is the C<sub>3</sub> pathway. Maize (<em>Zea mays</em>) shows the C<sub>4</sub> pathway as it grows in dry tropical climates.</div>

answer:
<div class="solution">Grass is at the First Trophic level as it is a producer. It can convert sunlight to chemical energy hence it is a transducer. Grasshoppers (herbivores) eat grass and hence are primary consumer at second trophic level. Rodents eat Grasshoppers and thus are secondary consumers and also primary carnivores at third level. Cats eat Rodents and are Tertiary consumer and secondary carnivores at fourth trophic level.</div>

The correct answer is:

answer:
<div class="solution">Cell wall is the outermost layer in the eukaryotic cells (absent in animals). It is a non -living and rigid layer. The main function is to protect the cells and also to give shape to the cells. It also prevents entry of unimportant substances. Young cells contain three layers: Primary wall, middle lamella and Secondary wall. Primary wall is responsible for growth and hence it is not seen in adult cells. Middle lamella is seen in all types of cells. This contains calcium pectate which helps to stick to the neighbouring cells. Plasmodesmata connects the middle lamella and cytoplasm of neighbouring cells.</div>

The correct answer is:
<span class="option-value">Detritivores</span> </div>

answer:
<div class="solution"><p>Detritivores are heterotrophic organisms that obtain nutrients by consuming detritus that is the decomposing plant and animal remains.</p><p>Benthos is the community of organisms that live on, in, or near the sea bed, also known as the benthic zone. As no light is available at this zone of sea, the energy source for deep benthic ecosystems is often organic matter from higher up in the water column which drifts down to the depths. This dead and decaying matter sustains the benthic organisms, and therefore, most organisms in benthic zone i.e., in deep oceanic waters, are scavengers or detritivores.</p></div>
