Answers

Answer 1
Answer: The answer is C). Lysosomes.

A lysosome is spherical membrane-bound organelle. In the lysosome, there are many hydrolytic enzymes which role is to break down different kind of molecules and components used by the cell. The pH inside of the lysosome is low (acidic: 4.5 - 5.0) which is optimal for enzymes. Also, there are substances involved in energy metabolism, cell signalling, etc.

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla? What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla? a.Shared DNA sequences b.Shared morphology c.Shared patterns of development

Answers

Answer:

The correct answer is option a. "Shared DNA sequences".

Explanation:

The most reliable evidence that suggest that vertebrates are more closely related to echinoderms than are any other invertebrate phyla is the fact that vertebrates share DNA sequences with echinoderms. Among the different genes that have been analyzed between vertebrates and echinoderms, the genes involved in immunology and biomineralization are the ones practically identical among these two categories of species.
