The diagram below shows three fossils in layers of rocks.

Which of these conclusions is most likely correct about the organisms whose fossils are shown in the diagram?

A. Organism A evolved from organism B

B. Organism A evolved from organisms C

C. Organism B evolved from organisms C

D. Organism B evolved from organism A

C.

Explanation:

Organism B and C look quite similar to each other and so it makes sense that organism B evolved from organism C

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
