The correct answer is "receptors".
Explanation:
Virus infect and reproduce by recognizing specific receptors in their host cells. Virus-receptor binding is highly specific, this is the reason why some virus can infect only certain animals or plants at specific tissues. If the virus that causes avian flu attaches only to the cells of the lower part of the respiratory system, it is very likely that these cells have specific receptors that are not present in the upper part of the respiratory system, receptors that the viruses recognize.
Answer:
a trait that gives an organism a reproductive advantage in the current environment
Explanation:
An adaptation is a trait that provides an advantage to the individual in which it is present by making the individual more adaptable to its environment and as the result, the individual survive to reproductive age and able to produce more offspring than less adapted individual of its population.
So the trait gives an individual or organism a reproductive advantage in the current environmental situation. The trait or allele that helps in adaptation comes due to mutation or variation from meiosis or gamete fusion.
