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.
An alternation of generations for plants include a haploid gametophyte and a diploid sporophyte.
Answer: There are two kinds of communication in the world of living cells. Communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling. An easy way to remember the distinction is by understanding the Latin origin of the prefixes: inter– means “between” (for example, intersecting lines are those that cross each other) and intra– means “inside” (like intravenous). Chemical sign
Explanation:
The body constantly makes new cells for the purposes of growth or the replacement of old, damaged, or recently dead cells.
