Answer: D. Earth’s outer core is deeper within Earth than oceanic crust is
Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.
<h3>What is an amphipathic molecule?</h3>
An amphipathic molecule is a compound that has a hydrophilic region and a hydrophobic region.
Phospholipids are the main constituent of the cell membrane and this lipid matrix.
The number of double bonds in hydrocarbon tails affects membrane fluidity by generating a "kink" in the fatty acid chains.
Cholesterol content alters fluidity because this lipid has free movement in the membrane.
Phospholipids and steroids such as cholesterol are amphipathic molecules, whereas membrane fluidity refers to the movement of the constituents of the cell membrane.
In conclusion, Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.

Answer:
a. What is the manipulated variable? the angle of incidence of the radiant energy
b. What is the responding variable? the rate of temperature rise on the paper surface
c. Identify one controlled variable? the distance of the paper to the lamp
Explanation:
- Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the angle of incidence of the radiant energy to evaluate how it affects the rate of temperature rise of the surface.
- Responding variable: Refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the rate of temperature rise on the paper surface, and its value depends on the angle of the paper.
- Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the distance to the lamp is the controlled variable, as it was the same for each of his trials.

His decision to make these lifestyle changes is most likely based on his knowledge that <span>they have higher rates of hypertension and obesity.
High amounts of salt can lead to many problems in anyone's body, this doesn't only refer to African Americans. However, if John doesn't exercise, he might get fat because he may be prone to obesity.
