Answer from: Savagepanda911

This exchange is crucial on order to attain homeostasis

Explanation:

Substances may be transported down or against an electrochemical gradient.

Downhill transport occurs by diffusion, (simple or facilitated), and requires no input of metabolic energy.

Uphill transport occurs by active transport, (primary or secondary).

Primary active transport requires a direct input of metabolic energy while Secondary active transport utilizes an indirect input of metabolic energy.

The differences in solute concentration across cell membranes are created and maintained by energy-consuming transport mechanisms in the cell membranes.

The endocrine system pairs with the nervous system to achieve homeostasis within the body. Hormones are secreted to effect their actions on target tissues.

Cells continually exchange materials and information with their environment. This exchange is crucial for maintaining a balance of materials across the cell body and making it sure that the level of homeostasis is remained unchallenged due to any reason of factor.

Explanation:

Homeostasis is the process of balancing all the required solutes and solvents along with the materials that are the requirement for the cells and the organisms as well that it can survive inside the environment.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

Which is used to copy dna for dna fingerprinting?
