which-method-can-be-used-to-find-out-the-strength-of-reducantoxidant-in-a-solution-explain-with-an-example-34158

question:
<div class="question">Which method can be used to find out the strength of reducant\oxidant in a solution? Explain with an example.</div>

answer:
<div class="solution">Strength of a reductant (reducing agent) or oxidant (oxidising agent) can be found out by measuring the relative electrode potential when it's connected in a solution using a cell.<br/>For example, $\mathrm{Fe}^{3+} / \mathrm{Fe}$ is the element we want to test with the Standard Hydrogen electrode (SHE). The half-cell reaction for $\mathrm{Fe}$ and $\mathrm{H}$ are given below:<br/>$\begin{array}{ll}\mathrm{H}^{+}+\mathrm{e}^{-} \rightarrow \mathrm{H}_2 ; &amp; \mathrm{E}^{\circ}=0.0 \mathrm{~V} \\ \mathrm{Fe}^{3+}+\mathrm{e}^{-} \rightarrow \mathrm{Fe}^{2+} ; &amp; \mathrm{E}^{\circ}=0.77 \mathrm{~V}\end{array}$<br/>When any element needs to be evaluated it is placed as an electrode with SHE. The amount of emf it generates in the cell can be considered as the potential of the element.<br/>$\mathrm{E}^{\circ}$ cell $=0-0.77$<br/>$\mathrm{E}^{\circ}$ cell $=0.77$<br/>The above assumed configuration of $\mathrm{Fe}$ being anode can be reversed and hence strength $\mathrm{Fe}$ as a reductant can be established. Hence the strength of an oxidant can be determined.</div>

answer:
<div class="solution"><p>The reagent used in Lucas test are conc. HCl+ZnCl<sub>2</sub>. It gives the white turbidity or cloudiness with alcohols. It is used to distinguish between primary, secondary and tertiary alcohol. Primary alcohol give the white turbidity in 30 min. Secondary alcohol give the white turbidity in 5 min. Tertiary alcohol give the white turbidity immediately. But phenol and enol can not give Lucas test.</p><p>n-butanol is a primary alcohol and tertiary alcohol, benzyl alcohol,allylic alcohol give the turbidity immediately.</p></div>

answer:
<div class="solution">Lymphoid organs are Primary and secondary. Primary lymphoid organs are those in which immature lymphocytes become antigen sensing cells. These organs are bone marrow and thymus. Secondary lymphoid organs are those that receive cells from bone marrow and thymus. These organs are lymph nodes, Spleen, peyer's patches etc.Spleen is known as the blood bank of the body. Histologically it shows two regions: the red pulp and the white pulp. The red pulp contains damaged erythrocytes as speen is the graveyard for these cells. White pulp contains lymphocytes and phagocytes and these cells trap the microorganisms.</div>

The correct answer is:
<span class="option-value">Shifting endangered species out of their natural habitat to special setting</span> </div>

answer:
<div class="solution">Evil Quartet is four major causes of biodiversity loss which include: Habitat loss and fragmentation, over-exploitation of natural resources by humans example: rainforests destroyed for cultivation. Alien species invasion-example: introduction of Nile perch led to the destruction of species of cichlid fish.

<div class="solution">Given eq $^{n}$ is $\left(x^{2}+2\right)^{2}+8 x^{2}=6 x\left(x^{2}+2\right)$<br/>$\Rightarrow x^{4}+4 x^{2}+4+8 x^{2}=6 x^{3}+12 x$<br/>$\Rightarrow x^{4}-6 x^{3}+12 x^{2}-12 x+4=0$<br/>$\left(x^{2}+2\right)^{2}+8 x^{2}=6 x\left(x^{2}+2\right)$<br/>$\Rightarrow x^{4}+4 x^{2}+4+8 x^{2}=6 x^{3}+12 x$<br/>$\Rightarrow x^{4}-6 x^{3}+12 x^{2}-12 x+4=0$<br/>This can be factorised into $\left(x^{2}-4 x+2\right)\left(x^{2}-2 x+2\right)=0$ Consider, $x^{2}-2 x+2=0$<br/>Roots are $\frac{-(-2) \pm \sqrt{(-2)^{2}-4(2)(1)}}{2(1)}=\frac{2 \pm \sqrt{4-8}}{2}$<br/>$=\frac{2 \pm \sqrt{-4}}{2}=\frac{2 \pm 2 i}{2}=1 \pm i$<br/>Also, this equation is satisfied by $1 \pm i$. Hence, required<br/>roots are $1 \pm i$.</div>

<div class="correct-answer">
The correct answer is:
<span class="option-value">Blood is a specialised connective tissue</span> </div>

answer:
<div class="solution">Connective tissue is the most abundant tissue in animals. This tissue is further divided into three types: Loose connective tissue, dense connective tissue, and specialized connective tissue. Loose connective tissue shows a matrix with cells and fibers. These are areolar and adipose tissue. Dense connective tissues are tendons and ligaments. These are known as dense as fibers and cells are densely packed in the matrix. Specialized connective tissues are fluid connective tissues or supporting connective tissues. Fluid connective tissues are blood and lymph as these are fluid and thus fibres are absent. Supporting connective tissues include bone and cartilage as these have lacunae.</div>

<div class="correct-answer">
The correct answer is:
<span class="option-value">The cells are compactly packed with little or no intercellular matrix</span> </div>

answer:
<div class="solution">Epithelial tissues are the major tissue in glands and form the outer covering or layer of all body surfaces and organs. It consists of closely aggregated cells that adhere firmly to each other and forming either single or multiple layers. Due to the cells being tightly packed there is the very little intercellular matrix. The intercellular matrix consists of protein and is on the cell membrane of epithelial cells</div>

The correct answer is:
<span class="option-value">Genus Triticum, family Poaceae, order Poales, Class Moncotyledonae.</span> </div>

answer:
<div class="solution">The botanical name of wheat is <em>Triticum aestivum</em>. So the genus of wheat is Triticum. Wheat belongs to the Poaceae or Gramineae family. It is a big and nearly universal family of grasses. The stem of grass is called a culm. The flowers of Poaceae are characteristically arranged in spikelets and enclosed by bracts. Those species come in order Poales they show pollination by winds i.e.anemophily. Single cotyledon is present so they belong to Monocotyledonae class.</div>

answer:
<div class="solution">The mode of arrangement of sepals or petals in the 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.<br/><br/>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 (Figure A). When sepals or petals in a whorl just touch one another at the margin, without overlapping, as in <em>Calotropis</em>, it is said to be valvate (Figure B). If the margins of sepals or petals overlap one another but not in any particular direction as in <em>Cassia</em> and Gulmohar, the aestivation is called imbricate (Figure C). 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 (Figure D).</div>

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

answer:
<div class="solution">Menstrual cycle consists of changes in the ovary and the uterus simultaneously. It begins with the menstrual or bleeding phase. This represents the shedding of the endometrium of uterus and unfertilized secondary oocyte. This phase is followed by the follicular phase as follicles start developing in the ovary. At the same time the shedded endometrium starts its preparation and this is termed as proliferative phase. The mid of 28-day cycle shows the ovulatory phase that is Graffian follicle from ovary releases secondary oocyte in the oviduct. This is followed by the formation of a corpus luteum and is known as Luteal phase. The secondary oocyte in the oviduct can undergo fertilization hence the uterus prepares itself to receive the fertilized egg by forming secretory glands i.e. secretory phase is seen. As no fertilization takes place the secondary oocyte now starts travelling towards the uterus to shed along with the endometrium i.e. new menstrual cycle begins.</div>

answer:
<div class="solution"><strong>Ovulatory phase/Pre-luteal/Post-follicular: </strong>During this phase, ovulation takes place. It usually occurs on the 14<sup>th</sup> day of the cycle of 28 days menstrual cycle. The mature Graafian follicle ruptures due to LH secreted by the pituitary. Due to LH surge, the Graafian follicle ruptures and releases the secondary oocyte in the abdominal cavity.</div>

answer:
<div class="solution">The diagram represents the class Cyclostomata. The body is elongated, eel-like with median fins and cartilaginous fin ray. The paired appendages are absent, tail is diphycercal. Skin is soft, smooth and containing unicellular mucous glands, but no scales are present. Notochord persists throughout life. Imperfect neural arches over notochord represent rudimentary vertebrae. The mouth is ventral, suctorial and circular with denticles. In lateral sac-like pouches of the pharynx, 5-16 pairs of gills are present, while gill-slits are present in 1-16 pairs. Air bladder is absent, and they are mostly poikilotherms.</div>

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

answer:
<div class="solution">Primary treatment is a physical process which involves sequential filtration and sedimentation. Suspended solids are removed in stages; initially, floating debris is removed by sequential filtration. Then the grit (soil and small pebbles) are removed by sedimentation. All solids that settle form the primary sludge and the supernatant forms the effluent. The effluent from the primary settling tank is taken for secondary treatment.</div>

Symptoms of these disease include internal bleeding, muscular pain, fever, anemia and blockage of the intestinal passage. The eggs of the parasite are excreted along with the faeces of infected persons which contaminate soil, water, plants, etc. A healthy person acquires this infection through contaminated water, vegetables, fruits, etc.<br/><br/><em>Wuchereria (W. bancrofti</em> and <em>W. malayi),</em> the filarial<br/>worms and Malaria causing <em>Plasmodium</em> are digenetic as they require two hosts. The two hosts are primary or definitive and secondary or intermediate. Definitive hosts are responsible for maturity and sexual reproduction of the organism. intermediate hosts harbour the sexuall immature organisms.</div>

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

answer:
<div class="solution">Primary consumers are herbivorous organism, that feed on producers. In a food chain, grasshoppers are primary consumers, phytoplankton are producers, and wolf and lions are secondary and tertiary consumers respectively.<br/>Related Theory<br/>The amount of energy flow decrease with successive trophic levels as only $10 \%$ of energy is transferred from one trophic level to the next successive level. The energy is lost in the form of respiration and other vital activities to maintain life. If more trophic levels are present, the residual energy will be limited and decreased to such an extent that it cannot further support any trophic level by the flow of energy. So the food chain is generally limited to 3-4 trophic levels only.</div>

It is found upon articular surfaces at joints of long bones from articular cartilage, coastal cartilages at the ventral ends of the ribs. It helps to from the nose, larynx, trachea, bronchi and bronchial tubes leading to the lungs.<strong>Fibrocartilage</strong>  (fibrous cartilage) carries thick dense bundles of white collagen fibres in matrix. They are the strongest cartilage. They occur in joints between vertebrae and also pubic symphysis.<strong>Tendon</strong>  is a very dense, strong fibrous connective tissue made of collagen fibres. Tendon connects a skeletal muscle to a bone.</div>

<span class="option-value">The main antibody formed during the secondary response against a previously encountered antigen is <math xmlns="http://www.w3.org/1998/Math/MathML"><mi>IgM.</mi></math></span> </div>

answer:
<div class="solution"><p>Acquired immunity is pathogen-specific. It is characterised by memory. This means when our body encounters a pathogen for the first time it produces a response called primary response which is of low intensity<strong>. Subsequent encounter with the same pathogen elicits a highly intensified secondary or anamnestic response</strong>. This is ascribed to the fact that our body appears to have memory of the first encounter. The  primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes.</p><p>The B-lymphocytes produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies. The T-cells themselves do not secrete antibodies but help B-cells to produce them. Different types of antibodies are produced in our body. IgA, IgM, IgE and IgG are some of them. Though IgG is the most common antibody formed by the memory cells, IgA- and IgE-expressing B-cells play an important role in the secondary immune response.</p></div>

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

answer:
<div class="solution">Endangered plants may be preserved in part through seed bank or germplasm bank. The term seed bank sometimes refers to a cryogenic laboratory facility in which the seeds of certain species can be preserved for up to a century or more without losing their fertility. It can also be used to refer to a special type of arboretum where seeds are harvested and the crop is rotated. For plants that cannot be preserved in seed banks, the only other option for preserving germplasm is in vitro storage, where cuttings of plants are kept under strict conditions in glass tubes and vessels.</div>

correct_option:
<div class="correct-answer">
The correct answer is:
<span class="option-value">Secondary cell wall</span> </div>

answer:
<div class="solution">Vacuoles are membrane bound storage organelles found in plant cells and animal cells. They are in larger size in plants compared to animal cells. The membrane of vacuole is called as tonoplast. <br/><br/>The cell wall found around the cells of plants contain multiple layers. The outermost thin, flexible and extensible layer is the primary cell wall layer of the plant. The thick layer sandwiched between the plasmalemma and primary cell wall is the secondary cell wall. The middle lamella connects the adjacent cell walls of the cells and is rich in pectin. It also forms the plasmodesmata.</div>

The correct answer is:
<span class="option-value">Growth is regarded as one of most fundamental and conspicuous characteristics of living being.</span> </div>

answer:
<div class="solution">All living organisms grow. Growth is permanent and irreversible change in size, shape, volume and dry weight. Growth can be intrinsic and extrinsic. Non-living also grow but their growth is extrinsic (surface growth due to deposition of substances) whereas living organisms exhibit intrinsic growth (internal growth), intrinsic growth results due to metabolic activity. Plants show Indeterminate growth i.e. grow throughout the life while animals grow only up to certain age. Chapter: Plant growth and Development</div>

answer:
<div class="solution">India has also a history of religious and cultural traditions that emphasised protection of nature. In many cultures, tracts of forest were set aside, and all the trees and wildlife within were venerated and given total protection. Such sacred groves are found in Khasi and Jaintia Hills in Meghalaya, Aravalli Hills of Rajasthan, Western Ghat regions of Karnataka and Maharashtra and the Sarguja, Chanda and Bastar areas of Madhya Pradesh. In Meghalaya, the sacred groves are the last refuges for a large number of rare and threatened plants.</div>

answer:
<div class="solution">Stratification in the field of ecology refers to the vertical layering of a habitat, the arrangement of vegetation in layers. It classifies the layers (singular: stratum, plural: strata) of vegetation largely according to the different heights to which their plants grow. Species diversity is defined as the number of different species present in an ecosystem and relative abundance of each of those species. Diversity is the greatest when all the species present are equally abundant in the area. Thus, both are the structural aspects of the ecosystem.</div>
