The answer is D. Bacteria are used to make virus vaccines
Answer:
appearance, development, and behavior
Explanation:
The phenotype, similar to the genotype, can be observed in two senses: wider and narrower. In a broader sense, a phenotype is a set of all morphological and physiological properties by which an organism is recognized and by which it differs from other organisms.
When we look at only one trait, then it is the narrower meaning of the phenotype. What will be the influence of genotype on phenotype depends not only on the genetic basis but also on the action of environmental factors in which the organism develops.
The answer is that they treat bacterial infections.
The unusually high frequency of "blue skin" in the area is an example of <u>genetic drift</u>.
<u>Explanation:</u>
It is a shift in the occurrence of an established gene variant within a population due to spontaneous organism screening. The offspring alleles are a composite of those in the parents and opportunity has a role to play in deciding whether or not a given person persists and reproduces.
The bottleneck impact is an interesting instance of genetic drift which take place when the population size is drastically reduced. Occurrences like natural disasters such as earthquakes, floods, fires can destroy a city, eliminate most people and leave a tiny, random assortment of survivors remaining.
Option A,
both limit movement of substances through the system
The sphincter muscle usually surrounds the openings in the body such as urethra, anus and performs the function of tightly closing the openings.
