Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Explanation:Plants will not just have to rely on one animal to help reproduce. Plants can mimic things such as scents or looks to be an incentive for other animals. Wind and water can also help transport pollen. Plants always have pollinators such as wind, water, insects, and animals. Plants use mimicry in order to attract the biotic pollinators. Plants will never have trouble reproducing because they have so many different pollinators.

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.
