Vacuoles <span>can be used by cells to store energy, form biological membranes, and serve as chemical messengers</span>
Answer:
A,C, D
Explanation:
Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
Between time points C and D, drug-resistant bacteria were reproducing faster than non-drug resistant bacteria were dying.
The few drug-resistant bacteria in the population reproduced, quickly leading to a large drug- resistant population.
There is no indication that a second antibiotic was used, so it is not possible to assume a second drug-resistance mutation occurred. There is also no indication that antibiotics were discontinued.
Rudolf Virchow was the scientist whose revolutionary theory, contending that cells only arise from other cells, challenged the theory of spontaneous generation. It is a site of steroid synthesis, drug detoxification, and lipid metabolism.
What is metabolism?
- Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body's cells that change food into energy.
- Our bodies need this energy to do everything from moving to thinking to growing.
- Specific proteins in the body control the chemical reactions of metabolism.
- The chemical processes that let you stay alive are an example of metabolism.
- The rate at which you burn fat and calories you consume is an example of metabolism. The processing of a specific substance within a living cell or organism.

The temperature of the food be checked as soon as they are received from
the delivery person. This should be done with the aid of a thermometer.
<h3>Food Storage conditions.</h3>
Food is a very important part of our daily life and special care must be taken
to ensure that they are properly stored under the right conditions to inhibit
the growth of microorganisms.
Food not properly stored under the right temperature favors growth of
microbes. This thereby causes food poisoning and other serious conditions
when eaten.

Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.
