The answer is; endoskeleton
An endoskeleton allows for smooth and steady growth unlike in an invertebrate with an exoskeleton that needs to shed their skeleton during irregular growth spurts. An endoskeleton is significant for leveraging (like an anchor) skeletal muscles hence enabling the animals to grow big and is able to support their own weight.
Is necessary for the absorption of vitamin B12 in the small intestine. Chief cells, Located primarily in the basal areas of gastric glands are chief cells, which secrete pepsinogen, the inactive proenzyme form of pepsin.
<h3>Which vitamin requires intrinsic factor which is secreted by the stomach in order to be absorbed?</h3>
Intrinsic factor is a protein that aids intestines absorb vitamin B12. It is created by cells in the stomach lining.
Thus, Chief cells,Located primarily in the basal areas of gastric glands are chief cells, which perspire pepsinogen, the inactive proenzyme form of pepsin.

Answer:
C. <em>Clostridium</em> and <em>Bacillus</em>.
Explanation:
<em>Bacillus </em>and <em>Clostridium</em> are the gram-positive bacteria and form endospores. Endospores are the resistant dormant structures formed by some gram-positive bacteria.
These bacteria form the endospores within their vegetative cells. The endospores are highly resistant to environmental stress conditions and make these bacterial genera the dangerous pathogens.
Answer:
<em>Yes, the statement is accurate.</em>
Explanation:
A hypothesis can be supported through experiments but we cannot say that the hypothesis is exactly correct because there might be other unknown factors which are unmeasured or unobserved which might be influencing our hypothesis. There are many studies in which a proven hypothesis was proven wrong due to many other factors or influences. Hence, a hypothesis can be supported but there are always chances that other factors might be being ignored which might influence the hypothesis.
Water is critical in all life. This is because it is important in the biochemical process of the cell. Take an example; water is consumed in most hydrolysis reaction in the body and is also significant in the regulation of blood pressure. Therefore even microbial activity will be reduced during water scarcity. Subsequently, nitrification process by nitrifying bacteria will definitely reduce in dry summers.
