and the second?
It has a robust, streamlined body with a long, pointed snout and relatively small eyes and has five pairs of gill slits.
Blacktip shark
The blacktip shark has a robust, streamlined body with a long, pointed snout and relatively small eyes. The five pairs of gill slits are longer than those of similar requiem shark species.
what bacterial parts are vital to a bacterium Prokaryotic microorganisms what do you mean by bacteria? They are a type of biological cell. describe their intracellular structures? It is surrounded by a cell membrane which encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of the cytoplasm. and extracellular? Around the outside of the cell membrane is the cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by peptides containing D-amino acids. what are their origins? The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. how about their metabolism? It exhibit an extremely wide variety of metabolic types which is classified into nutritional groups on the basis of three major criteria. how do they reproduce? It reproduces through binary fission, a form of asexual reproduction. are they able to communicate? This bioluminescence often occurs in bacteria that live in association with fish, and the light probably serves to attract fish or other large animals. the form of reproduction that you just mentioned, what exactly is it? A type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. who else reproduces this way? It is und in nearly half of the animal phyla, for example, Parthenogenesis occurs in the hammerhead shark and the blacktip shark. who are their predators? Organisms such as "Myxococcus xanthus" what is their relation to pathogens? If it form a parasitic association with other organisms, they are classed as pathogens. can you please describe the first type of shark that you had mentioned previously? They are a group of sharks that form the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a cephalofoil.

Blacktip shark [SEP] Description
The blacktip shark has a robust, streamlined body with a long, pointed snout and relatively small eyes. The five pairs of gill slits are longer than those of similar requiem shark species. The jaws contain 15 tooth rows on either side, with two symphysial teeth (at the jaw midline) in the upper jaw and one symphysial tooth in the lower jaw. The teeth are broad-based with a high, narrow cusp and serrated edges. The first dorsal fin is tall and falcate (sickle-shaped) with a short free rear tip; no ridge runs between the first and second dorsal fins. The large pectoral fins are falcate and pointed.
