The life that exists on Earth today likely arose from a single common ancestor. Judge each statement below and select the ones that explain how natural selection has played a role in the diversity of life on Earth from that single ancestor. Select all that may apply.

the answer would be b

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

b. climate change will cause an increase in biodiversity of all ecosystems.

hope this
