Water is used in many reactions in the body, both enzymatic and chemical. Water within blood and lymphatic system is responsible for the transport of hormones, antidotes oxygen and nutrients.
Metabolism can be described as entirety of chemical reactions which take place within a cell, the result of which is energy for processes which take place in the body.

Answer:
Change occur in the genetic makeup.
Explanation:
Brian means that the change occur in the genetic makeup of the mitochondrial DNA that change the structure as well as the function ability of mitochondria which is responsible for the generation of energy for the cell. The mitochondrial DNA are passed from mother to offspring through the egg cell. He signify mitochondrial DNA because the change occur only in the mitochondrial DNA not in the whole organism's DNA.
Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
The question is incomplete as it does not have the options which are:
A. Gram-negative bacilli cannot cause harm to the cell; only Gram-positive bacilli can harm the cell.
B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.
C. Gram-negative bacilli excrete elaborate exotoxins that interfere with cellular production of ATP.
D. Gram-negative bacilli enter the cell and disrupt its ability to replicate.
Answer:
B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.
Explanation:
Gram-negative bacteria are pathogenic in nature due to the composition of their cell wall. Their cell wall contains an additional layer of a molecule called lipopolysaccharides or LPS.
The LPS layer is toxic in nature and is known as endotoxin and is involved in the pathogenicity of the bacteria as the toxin causes the injury to the Endothelial cell membrane of the host cell.
When the bacteria cell is lysed and the LPS circulates in the blood, then LPS binds the receptors and acts on CD14. This attracts the neutrophils at the site and can cause vascular injury due to increased capillary permeability.
Thus, Option-B is the correct answer.
