Answer:
to understand the human and animal behaviour
Explanation:
By looking at the biological bases of human behavior, psychologists are better able to understand how the brain and physiological processes might influence the way people think, act, and feel.
Cell wall, cell membrane, nuclear membrane.
Answer:
Angle of light source
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response, which is the dependent variable.
In this question, a student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third. This shows that the variable being manipulated (independent variable) is the ANGLE OF THE LIGHT SOURCE.
the answer is a <u><em>phospholipid bilayer</em></u>
it's called phospholipid because it's made of a group of lipids that has a phosphate group and bilayer because it's made of hydrophilic heads that are exposed to the solution and hydrophobic tails that are directed inwards
Answer:
11B (reproduce). 12C (be eaten). 13A (variation). 14C (better adapted). 15C (Darwin). 16A (evolved). 17C (competition).
Explanation:
11 - The key principle underlying evolution by natural selection is that traits are only passed on if the organism survives long enough to reporduce. An adaptation that increases its likelihood of survival will therefore increase the chance it will reproduce.
12 - Deer rely on their brown fur to remain camouflaged in the forest so that predators can't see them. A white deer will stand out and will be seen by predators and eaten.
13 - This is the definition of variation. The variation becomes an adaptation if it actually benefits the organism in some way in its environment. A variation could also be neutral (doesn't affect the organism) or deleterious (bad).
14 - See previous question.
15 - Darwin developed the theory.
16 - This is describing the process of evolution.
17 - This is an example of competition.
