The ___ receptor is upregulated when you chronically use, then withdraw, from alcohol.

Kipish [7]

This would be an example of negative feedback because the body isn’t trying to surpass a set point. It’s trying to maintain the amount of food in the stomach at that point.

Which of the following would NOT be a constituent of a plasma membrane? Select one: a. messenger RNA b. phospholipids c. glycopr

Katyanochek1 [597]

Answer:

The correct answer is a. messenger RNA

Explanation:

The plasma membrane mainly contains lipids, proteins, and carbohydrates. Phospholipids make the bilayer of the plasma membrane. Carbohydrates can be found attached to proteins and lipids.

The carbohydrates that are attached to lipids are called phospholipids and those with proteins are called glycoproteins. mRNA is the molecule which is not the part of the plasma membrane. mRNA is produced in the nucleus through the transcription process and is responsible for proteins formation.

So phospholipids, glycolipids, and glycoproteins are the part of the plasma membrane but not messenger RNA.

aBcd
abCD
abCd
abcD
abcd

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.

The number of gametes with different combinations is 2ⁿ, where

n = number of homologous pairs.

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.

A.......B.........C........D → ABCD
