Art [367]3 years ago

Answer:

Protein is the important biomolecule that acts as building block of the protein. Proteins are inserted into the biological membrane and consists of transmembrane and integral membrane proteins.

The alpha helices and beta sheets are present in the bio membrane. The organism living at low temperature has high alpha helices and low beta sheets because alpha helices has high mobility, less rigidity and makes enzyme active at low temperature.

Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the
erastova [34]

Complete question:

Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.

A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).

Answer:

The probability that the second child will also have the disease is 1/16.

Explanation:

<u>Available data:</u>

  • Two genes independently inherited: one for blood type, the other for disease
  • Man with type A blood  x  Woman with type B blood
  • Both parents are heterozygous for the gene that causes the disease; Dd

If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.

sasho [114]

Answer:

Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function.

Explanation:

Hypertrophy is the term used to describe an increase in cell size. If the enough number of cells in some organ hypertrophy, the whole organ will also  hypertrophy.

Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function. It can take place in a number of human organs and tissues such as the liver, the kidneys, the heart, the spleen, the lungs, the pancreas etc.

Which correctly lists the three gases that are part of Earth’s cycles in both the atmosphere and biosphere? radon, carbon monoxi
serg [7]

The three gases that are part of Earth’s cycles in both the atmosphere and biosphere are:

  • oxygen
  • - nitrogen
  • - carbon dioxide

<h3>Explain your answer?</h3>

The oxygen,  nitrogen, and carbon dioxide are the three gasses that are constantly moving through the atmosphere and biosphere in their own respective cycles.

The oxygen is used by the animals for breathing, but it is also released as a byproduct by the producers. The nitrogen is used as a food source for the producers, as well as the carbon dioxide which is crucial for the process of photosynthesis.

Thus, Part of them is released through decomposition, part by releasing them in the atmosphere or in the soil.
