The answer is a. evade predators.
Animals that live in taiga had to adapt to seasonal changes, by changing their fur or feather color. For example, snow-show hare and ermine live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way<span> it is more difficult for their predators to spot them.</span>
Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.
Explanation
The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).
Food storage and digestion take place inside a food vacuole in the cytoplasm of amoeba.<span> Once digested, it reaches each cell organelle.</span>
Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in the transfer of heat.
Answer:
intensity with which the rats pressed the lever
Explanation:
In research, there are two main variables which are <u>dependent</u> or <u>independent</u>.
Independent variables are controlled or manipulated by the experimenter and the independent variable in this experiment is the amount of light exposure.
The response or outcome, which is then measured is the dependent variable. In this experiment, the dependent variable is the intensity with which the rats pressed the lever with varying exposure to light.
In summary, the independent variable has a causal effect on the dependent variable so in this experiment the amount of light exposure has a casual effect on whether the rats would press a lever more.
