Answer:
C. homoplasies
Explanation:
Homoplasy refers to the presence of similar characters in different species. These similar features are not shared with their common ancestor and therefore, are not the result of convergent evolution. Mammals and birds have four-chambered hearts which was not present in their common ancestors (reptiles).
Therefore, the four-chambered heart is a homoplastic feature that developed independently in mammals and birds to meet their higher demand for oxygen to maintain the constant body temperature. The four-chambered heart keeps the deoxygenated and oxygenated blood separate to efficiently supply the oxygen-rich blood to cells.

Explanation:
Here is the correct sequence:
<span>B) The scientist puts the bacteria in three different environments:
high salt, medium salt, and low salt
</span>
<span>A) The scientist asks the question, Does salt help the growth of these bacteria?
</span>D) The scientist forms a hypothesis that higher concentration of salt may increase the growth of these types of bacteria.
<span>C) A microbiologist notices that some bacterial species thrive in salt water environments.
</span><span>F) The scientist finds that the high-salt environment has the most bacteria.
</span>
<span>E) The scientist publishes his report in a scientific journal.</span>
1) melts polar ice caps thus causing the sea levels to rise
2) warms the oceans above average, causing sea life to either to migrate to places where they were never found before or die
3)causes algae blooms/ red tides which harms wild life and humans
Plants and animal cells share a lot of similarities since they both belong to a same group of cells which is the eukaryotic cells. One similarity they share is the cell membrane. This is the part of the cell which surrounds the cytoplasm of a cell.
