Which biological scenario(s) best describes phenotypic plasticity for a trait? I. Each person has a specific blood type.
II. Red blood cell counts differ in higher altitudes.
III. One identical twin is taller than the other.
A)I only
B)II only
C)II and III only
D)I, II, and III

C) II and III only

Explanation:

Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.

Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.

Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.

answer: oof wait

explanation:

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
