Answer: The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. Changes in Earth's system affects the growth of life on Earth. ...

Answer:
Homologous characters indicate descent through modification from a common ancestor.
Explanation:
Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.
These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.
These homologous characters are common in organisms related and that share a <u>common ancestor</u>.
For example, whales, humans, and horses all have the same bones in the same order, but they matured differently in later embryological development. This is an example of homologous characters.
B. Populations are a group of the same species in a place at the same time.
