Answer:
Homologous structures
Explanation:
Homologous structures are basic organ structures that are similar, which are shared among organisms that are of the same ancestral line or origin. These homologous structures may not be similar in function or in appearance in the different organisms of an ancestral origin that share such structures. An example of basic organ structures shared by mammals is the forelimbs, which is present in bats, humans, cats etc.

The process of heat acclimatization requires tolerance of gradually increased activity in the hot environment. A healthy individual that is well adapted to the body’s physiological changes is said to have an improved heat tolerance. Heat acclimatization is extremely useful for athletes.
Shrinking sea ice has forced the polar bears to seek new food source.
<span>This statement is an example of a negative feedback: <span>The first enzyme in a reaction sequence lowers the activation energy of the reaction.
</span>In Biology, negative feedback always results in a reaction that has a decreased function. This type of feedback occurs as a response to a particular kind of stimulus.
Negative feedback is necessary because it lessens the overall output of a particular system; as this continually happens, the system begins to stabilize. In Biology, this is what any organic material always seeks to achieve, a level of stabilization known as homeostasis or equilibrium.</span>
