Answer:
the drive-reduction theory
Explanation:
The drive-reduction theory is one of the theories of motivation.
This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.
The theory targets homeostasis or biological balance.
When there is a need such as lack of water, the need would cause a drive to be developed (thirst).
The drive would activate a response (search for water to drink).
The response is then terminated when the need has been satisfied.

Hi,
A. Radioactive markers
Explanation

Best wishes!
Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️

Predator and prey populations affect each other because if a predator of one prey kills that one animal than that animal dies and the prey decrease by one and when one predator dies from being killed or just naturally dying, then the predators decrease by one.
