Hypercholesterolemia is a genetic disorder that causes blood cholesterol levels to be elevated. The H allele is incompletely dom

inant to the h allele, with hh homozygotes having extremely high levels of blood cholesterol. A husband and wife are both heterozygous for hypercholesterolemia. What is the probability that their first child will have normal levels of blood cholesterol?

Answer:

1 (100%)

Explanation:

H allele is incompletely dominant to the h allele =Hh ( normal levels of blood cholesterol)

hh homozygotes having extremely high levels of blood cholesterol =hh

If Hh × hh

The F1 generation = Hh, Hh, hh, hh

The probability that their first child will have normal levels of blood cholesterol;

= 1/1

= 1 (100%)

Your friend brings you rocks with a thick layer of oxidation weathering, and no other visible signs of weathering. this is a clu
Vsevolod [243]
<span>A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. There are three types of weathering, physical, chemical, and biological. For the physical weathering, there are two main types. Freeze-thaw cycles and exfoliation. Obviously the freeze-thaw cycles require water and the exfoliation generally happens through thermal expansion and contraction which doesn't require water. But since neither of these mechanisms were observed, that doesn't indicate if the area was wet or dry. Biological weathering is caused by plants or animals breaking down rocks via chemical (acid) or mechanical (root growth) means. Life generally indicates the presence of water, but since this form of weathering wasn't observed, we still don't have enough data. Chemical weathering is caused by rain water reacting with the rocks to form new minerals and salts. There are several types such as acidic rainwater dissolving part of the rock, and oxidation. With this in mind, let's take a look at the available options. A moist environment because there is a greater density of oxygen in the atmosphere in the presence of water. * Yes, we need a moist environment, but the density of oxygen is fairly constant world wide regardless of how moist or dry the environment is. So this is a bad choice. A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. * Water speeds up chemical weathering of all types. So this is the correct choice. A dry environment because the increased albedo of deserts encourages physical weathering processes such as oxidation. * Yes, the increased albedo of deserts does speed up spalling, but oxidation is a CHEMICAL weathering process, not a PHYSICAL one. So this is a bad choice. A dry environment because in the absence of water oxidation is the dominant weathering process. * Water speeds up oxidation quite a bit. And since the observed oxidation is thick, there's been quite a bit of weathering. So this is a bad choice.</span>

3. Were there any stages of the cell cycle that you did not observe? How can you explain this using evidence from the cell cycle
mario62 [17]

Answer:

The surface area of the cell increases to volume ratio

Explanation:

As a cell grows, the surface area of the cell increases to volume ratio. When cell division occurs, the surface area is distributed and each daughter cell have less surface area but with the passage of time, the surface area increases. The main function of mitosis is to increase the population of the cell, the cell must be divided into two daughter cells in the process of mitosis. Tumors occurs when the process of mitosis is uncontrollable. One observation that is found interesting while looking at the onion root tip cells is the multiplication of the cells by the process of mitosis.
