What has the study of fossils allowed scientists to do? A. Describe past environments and the history of life.
B. Study present ocean temperatures at different depths.
C. Analyze the chemical compositions of sedimentary rocks and minerals.
D. Predict which organisms will become extinct in the future

A.

Explanation:

I THINK it is A, because fossils are decomposed animal remains, right? So what I'm saying is that the answer is A, because the structure of the fossil could help tell how the creature (or plant) adapted in order to survive in its surroundings.

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

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.
