In a population that is in Hardy-Weinberg equilibrium, 64% of the individuals express the recessive phenotype for a particular g
Degger [83]

Answer:

Expected frequency of the recessive allele in this population = 80%

Explanation:

Given -

Recessive phenotype expressed by an individuals for a particular gene locus is 64%

Now as per Hardy-Weinberg equilibrium equation, the frequency of individual with recessive phenotype is represented by "q^{2}"

where "q" is the frequency for recessive allele.

Thus,

q = \sqrt{q^2} \\= \sqrt{0.64} \\= 0.8\\

Expected frequency of the recessive allele in this population = 80%

How is hydro electricity produced step by step explanation ​
timama [110]

Answer:

ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy

Explanation:

In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.

The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the na
erma4kov [3.2K]

Answer:

C. Nucleotide

Explanation:

There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.

A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;

A represents ADENINE

S represents SUGAR

P represents PHOSPHATE GROUP

Hence, the monomer is a NUCLEOTIDE.
