Cell differentiation is mostly directly regulated by THE DNA.
The DNA is a component of a living cell and is the one that is majorly responsible for directing cell differentiation. DNA molecules carries the genetic information and this information are incorporated into new cells during the process of cell differentiation. Cell differentiation process produced specialized cells.
The answer is membrane proteins.
Answer: The drive theory of motivation.
Explanation:
The drive threory of motivation is based on the principle that organisms have certain psycological or physiological needs (in this case, hunger). When those needs are not satisfied, a tension in the organism is produced, and with it a drive to seek the satisfaction of that need.
Because the substance the rat recieves is nonnutritive (it doesn't reduce the rat's hunger), we can clearly see that the rat isn't performing the response because of this drive, seeking for the satisfaction of its hunger, but is motivated by another feeling. Therefore, this observation is problematic for the drive theory of motivation.
Answer:
Seven other species are extinct, prehistoric species known from fossils.

It is classified under the family Giraffidae, along with its closest extant relative, the okapi.
