5. you have found the fossil of an ancient, extinct species. you compare it to a modern day living species that is closely related. which of the following could you reasonably expect to observe?
a) the fossil and the living species will have identical features
b) the fossil and the living species will have some similarities and some differences
c) the fossil and the living species will differ only in size
d) comparison of the fossil and the living species will reveal their common ancestor

Answer: B) The fossil and the living species will have some similarities and some differences.

Explanation:

When we compare a fossil and a modern day living species that are closely related, their close relation is determined because of the presence of some similarities. However, with the course of time the modern day  species acquire several new characteristics to adapt to their environment and thus, this results in differences between the two.

So, the fossil and the modern day living species that are closely related will have some similarities and some differences.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
