Explanation:
A cell's lipid bilayer allows to small uncharged substances such as: ions, hydrophobic molecules, oxygen and carbone dioxide to travel through the membrane by simple diffusion
Answer: because there is no sunlight
Explanation: Solar cells are also called as photovoltaic cells. They convert light energy to electricity

Explanation:
<h2>
Zone of physiological stress</h2>
Explanation:
For this particular species I would label 90°F to 94°F as the temperature zone of physiological stress.
We find that within this temperature range the number of individual in the population lessens. This means they are under certain physiological stress which limit there growth.
Again within 95°F–96°F we find that the number of individual is maximum. This means that the population can utilize the available resources to their maximum efficiency at this range. So, it is the optimum range.
Answer: An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.
Explanation: Example: What is a good outcome variable for deciding whether cancer treatment in a country has been improving?
A first thought might be "number of deaths in the country from cancer in one year." But number of deaths might increase simply because the population is increasing. Or it might go down if cancer incidence is decreasing. "Percent of the population that dies of cancer in one year" would take care of the first problem, but not the second.
This example makes the point that a rate is often a better measure than a count.
