Which biological scenario(s) best describes phenotypic plasticity for a trait?
DIA [1.3K]

Answer:

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.

Explain how the structure of your fingers is related to their grasping function.
Karolina [17]

<u>ANSWER:</u>

The muscles and joints allow the hands to perform their function of holding and grasping a wide variety of things.

<u>EXPLANATION:</u>

  • The bones of the hand including the 4 carpal bones, 5 metacarpal and 14 finger bones are all connected by joints and ligaments and these allow the hand to grasp things.
  • The wrist is made of "two parts of a joint" that allow the extension and stretching of hands.
