It is expected someone with emphysema has a lesser vital capacity than someone without the disease simply because it decreases the ability to recover air during the process of breathing.

An emphysema medical condition may be considered as a health problem that decreased the ability of the lungs to take air due to impairment in the process of exhalation, which causes shortness of breathing responses in the individual affected by this problem. Emphysema is caused by injuries that are able to affect the air sacs present in the lung tissues, which decrease the ability to interchange gases (oxygen and carbon dioxide) during respiration.

Therefore, with this data, we can see that emphysema is a medical condition that decreases the ability to breathe and thus also it is detrimental to the vital capacity of the lungs.

Elastance is the capacity of a lung to recoil or rebound after strain.

Respiration, a mechanism of gas exchange, is the major purpose of the lungs (or breathing). During breathing, Co₂, a metabolic waste product, exits the bloodstream while oxygen from air flowing enters. Reduced lung effect can be attributed to the lungs' diminished capacity to exchange gases.

Typically, you need one lung or more to survive. In one instance, a patient had to have both lungs extracted and it was maintained alive for six days on life support before receiving a lung transplant. Since one needs both lungs to survive, this is not a routine treatment.

It lends credibility to the theory that all species descended from a common ancestor. The term "homology" refers to the belief that all living things have a common ancestry.

This is because homology asserts that many individuals have the same embryological origin as specific organ structures. This structure is functional in some, but not in others, indicating that it was handed down from a common ancestor to subsequent generations.

Natural selection, as we know, is an evolutionary process in which certain members of a species had characteristics in their bodies that were advantageous to the environment in which they lived.

These organisms survived and passed these structures on to their descendants. For this reason, we can say that the presence of homology supports the standard component of the theory of evolution by natural selection because it supports the hypothesis that species descend from a common ancestor.

These creatures survived and passed on these structures to their offspring. As a result, the presence of homology supports the standard component of natural selection theory since it supports the premise that species descend from a common ancestor.

Explanation:

Double-stranded viral DNA is incorporated into a host cell as a form of genetic material.

The viral DNA is packaged within the viral capsid and is released into the cells of the host organism when the virus enters the cell. Once inside the cell, the viral DNA is uncoated and then incorporated into the host cell's own genetic material. This process, known as “genetic transformation”, is how the virus replicates its genetic material and spreads to other cells.

The incorporation of viral DNA into a host cell is an essential part of how viruses spread and cause disease. The viral DNA is able to take control of the host cell's normal cellular functions and cause it to produce more viral particles.

This process, termed “lytic cycle”, is necessary for the virus to spread and cause infection. In some cases, the viral DNA also integrates into the host cell's genome, allowing the viral genetic material to be passed down through generations of cells. This process, referred to as “lysogenic cycle”, can lead to persistent infections and chronic diseases.

In order to successfully incorporate its DNA into the host cell, the virus must first attach to the host cell's membrane. This is done by the virus making use of specific proteins known as “receptors” that are found on the cell's surface. When the virus attaches to the receptor, it is allowed to enter the cell. Once inside the cell, the viral DNA is then uncoated and incorporated into the host cell's own genetic material.

British land snails primarily occur in two extreme phenotypes. This is an example of disruptive selection, which means option C is the right answer.

British land snails are the native organisms of north west Europe. They are found in two extreme forms only because disruptive selection favors only extreme phenotypes to sustain in the changing environment, while the intermediate phenotypes are either rejected naturally by the nature or they fall prey to other large animals and so their population is very less in nature particularly their native habitat.

Disruptive selection causes extreme phenotypic population to get more easily adaptive in nature and helps them increase their population through reproduction. Thus extreme population has higher frequency than other variations present.

The best example of a Mendelian trait in humans is phenylketonuria. This illness is an illustration of a Mendelian trait since it is passed down from parents to children when both parents have heterozygous (Aa) and homozygous (Aa) circumstances.

Mendelian qualities are determined by all of Mendel's postulated Laws of Inheritance and are traits that are transferred from parents to children through dominant and recessive alleles of a gene. The lack of an enzyme that turns the amino acid phenylalanine into tyrosine is the root cause of the autosomal recessive inherited disorder. As a result, the amino acid builds up and is converted into the toxic form of phenyl pyruvic acid, which builds up in the brain of the person and causes r-e-t-a-r-d-a-t-i-o-n.

The two species must have shared a common ancestor 320 million years ago, since the neutral mutation rate of the molecular clock is one mutation per 40 million years and the two species differ by a total of eight mutations.

A molecular clock is a tool used by scientists to estimate the time since two species have shared a common ancestor. This is done by measuring the number of genetic differences, or mutations, between the two species. The molecular clock is based on the assumption that the mutation rate is constant.

In this case, we know that the neutral mutation rate of the molecule being used as a molecular clock is one mutation per 40 million years. This means that for two species to have a difference of eight mutations, it must have been at least 320 million years ago that they shared a common ancestor.

To arrive at this conclusion, we can use the following formula:

Number of mutations × Neutral mutation rate = Time since common ancestor

In this case, 8 mutations × 40 million years = 320 million years. This means that two species must have shared a common ancestor at least 320 million years ago for them to have a difference of eight mutations.

The molecular clock can be a powerful tool for scientists to estimate the time since two species have shared a common ancestor.
