Answer:
Mainly, the number of genes that control traits.
Explanation:
Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.
Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.
Mendelian inheritance would assume that the offspring would either be fair or dark only.
Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.
Hope you understood it.
Endoplasmic Reticulum (ER). This folded membrane forms sacs to store proteins or other substances. It creates a vast surface area where the manufacture of proteins and new membranes can take place. <span>Endoplasmic reticulum is a folded mass of membranes made of the same phospholipids found in the plasma membrane. There are two types of ER smooth (without ribosomes) and rough (with ribosomes)<span>

Active transport requires energy because unlike osmosis and diffusion which are passive transport methods which sees where the particles are moving along the concentration gradient, in active transport, the particles are moving against the concentration gradient and as such energy through ATP is needed for the particles to be transported.
Answer:
The correct answer is c. That is 9 protein to form each facet
Explanation:
Given that the capsids is 25-30nm in diameter and it contains 180 identical capsomeres, if the virus capsid has 20 facets in 180 capsomeres, then for each protein facet, it will contain 9 protein facets.
Thai is 180 capsomeres divided by total number of facets (20).
