When blood supplies oxygen and food to a cell surface and these molecules diffuse across, we might expect some "resting time." However, if we inspected most cell membranes in a living human body, we would find a nearly continuous flow of substances back-and-forth across the plasma membrane. Which of the following is not a reason why? a) Cell metabolism is constantly using up oxygen and raw materials; this lowers their concentration so more will diffuse into the cell. b) Cell metabolism is constantly producing waste molecules; this increases their concentration so more will diffuse out of the cell. c) Cells produce useful secretions; this increases their concentration and more will diffuse out of the cell. d) Cell metabolism constantly produces carbon dioxide in respiration; this increases its concentration so more will diffuse out of the cell. e) Cells are living entities and in order to live can never "rest".

The answer is part A

Explanation:

why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?

Answers

Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

What is likely to happen to a healthy population that is experiencing exponential growth?

Answers

What is likely to happen to a healthy population that is experiencing exponential growth is as a result of competition for limited resources, the population would quickly reach its carrying capacity and collapse. This is further explained below.

What is the population?

Generally, population is simply defined as the people who live anywhere.

In conclusion, a healthy population undergoing exponential expansion is likely to exhaust its carrying capacity and collapse as a consequence of competition for scarce resources.
