Answer: Correct options B, D and E.
Explanation:
In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)
Then the fish are the most primitive (being directly related to the first ancestor)., E is true.
We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.
So D is also true.
We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,
Answer: An abnormal increase/decrease in body temperature (no sweating/shivering)
Explanation: Homeostasis is the process by which the body regulates and equalizes functions within the body. An example of the human body maintaining homeostasis is body temperature. If the human body is too hot, then the body will activate the sweat glands to cool down. If the human body is too cold, the the body will shiver.
An imbalance in homeostasis however, would be the lack of the process that regulates body temperature. So an example of imbalance in the process of human homeostasis would be not shivering when cold and not sweating when hot.
<em>I know there are probably better examples of imbalances in the process of human homeostasis, but I hope that this explains it sufficiently enough and is a good-enough example. Have a nice day!</em>
-In Africa savanna more wildebeest are born than the environment can support. As a result over a period of years individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. This is referred to as natural selection.
