While race is more associated with biological traits, like your skin color, facial features, hair, etc., ethnicity is more about cultural identities and background. For example, you can be of Hispanic ethnicity and be of Caucasian race.
This is an example of Positive reinforcement.
Positive reinforcement is the addition of a reinforcing stimulus (giving the dog a treat) following a behavior (rolling over), that makes it more likely that the behavior occurs again.

This can also entail movement of individuals who carry an idea with them from one area to another area.
Answer:
Below
Explanation:
Cold environments (both polar and tundra) are found in high latitude areas and mountainous regions of the world. They have an extreme climate and unique characteristics such as the soil type and the plants and animals found there. The biodiversity in cold environments is relatively low because very few species survive there.
A limiting factor is something in a ecosystem that limits the growth of a species. In this case, cowbirds are limiting factors to wood thrushes because they lay eggs in the nests of wood thrushes, which is called "nest parasitism." A decrease in the carrying capacity—the number of living organisms that a region can support (without environmental degradation)—of wood thrushes could be caused by a decrease in the insect population size. The less insects, the less food. With less resources, the carrying capacity will decrease for wood thrushes. If the cowbird population were decreased, or the space or number of nesting sites were increased, the carrying capacity would increase, instead.
