Answer:

A. 1' ... 5'

Explanation:

The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.

Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.

Why is the model used to describe the plasma membrane called the fluid mosaic model?
mezya [45]

Answer:

Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.

Explanation:

The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.

What do the variables in the Hardy-Weinberg equation represent?
Yuki888 [10]

Answer:

p represents the frequency of the dominant allele (in decimal form) of a gene

q represents the frequency of the recessive allele (in decimal form) of a gene

These 2 alleles are different; one is dominant, one is recessive.

p^2 = the frequency of homozygous dominant individuals in the population (decimal form)

2pq = the frequency of heterozygous individuals in the population (decimal form)

q^2 = the frequency of homozygous recessive in the population (decimal form)
