Asexual reproduction is important because it can produce many off springs without finding a mate it is independent. Forms of life can't survive without reproduction. <span>Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. They are clones. The main process of asexual reproduction is mitosis. </span>

<h2>Asexual reproduction </h2>

Is a kind of reproduction through which generation arise from a unique organism. The inherit of the genes of a specific mother and father only. It does not include the union of gametes that essentially never improve the number of chromosomes. Asexual reproduction is the main method of reproduction for single-celled bodies example archaea and bacteria.

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how

vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

x(t) is the value at time t.

x 0 is the initial value at time t = 0.

r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

Which of the following is a necessary reactant for cellular respiration to occur?

IrinaVladis [17]

I believe the correct answer from the choices listed above is the third option. It is oxygen that is a necessary reactant for cellular respiration to occur. Cellular respiration, in a sense, is breaking down sugar in the presence of oxygen. Hope this answers the question.

An individual with Huntington disease has two normal parents. What are plausible explanations for this pattern of inheritance? C

Vitek1552 [10]

Answer and Explanation:

The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.

The Huntington disease characterizes for being,

Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.

Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.

Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.

Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.

There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called <u>"de-novo" mutations.</u> A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This <u>usually occurs in the paternal germinal line</u>, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.
