Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
Gatrectomy is a procedure that involves removal of a part of the stomach (partial gastrectomy) or the whole stomach (total gastrectomy). It is carried out to removal stomach cancer or stomach perforations. In this case, the nurses initial action will be first not to tamper with fresh surgery tubes and then call the primary health care provider for blood draining from the NG tube after the procedure (gastrectomy)
Cilia helps in movement of the organism, it can pass the content (gases like CO2, O2) so they can transport. It can migrate an organism to more sustainable environment
Hope this helps!
