The graph above displays the heights of an average population of humans. Use C.E.R. (Claim, Evidence, Reasoning) to answer the f

sladkih [1.3K]

Answer:

The graph shows the height in inches of determined human population and the pattern it shows is due to the height variations that exist between individuals, due to different factors, where the average height in the population is close to 69 inches, and most of the population has heights between 67 and 72 inches.

Explanation:

The height of individuals is the measurement, from head to toe, which is made standing up and barefoot.

The graph shows the frequency of people who have a specific height, where:

Claim: According to the graph, most people are between 67 and 72 inches tall. Heights below 63 and above 72 inches are less frequent and the average person is about 69 inches tall.

Evidence: The data provided by the graph support the claim that there is variation in height in the human population. When data on anthropometric parameters are to be obtained, a sample is chosen, measured under the same conditions and then taken to a graph showing the results.

Reasoning: variations in human height respond to several factors, mainly genetic and environmental factors.

Inheritance plays an important role in determining an individual's height, although it is a polygenic pattern of inheritance, where multiple genes determine the height an individual will have.

In general, the height between men and women differs but, in addition, the inheritance of this parameter is linked to race. There is no single gene that determines whether a person will be tall or short, nor are there dominant or recessive alleles.

The combination of information from several genes will result in the phenotypic expression of height in an individual and can increases the genetic variability for this trait. It should also be taken into account that genetic disorders can affect the development of normal height.

Environmental factors and habits, especially food and family environment, are determinants of the height a particular individual will have.

A person had an infection of his Peyer's patches and developed intestinal cancer. How could these two events be related?

LekaFEV [45]

This is because of the location at which the Peyer's patches develop or are formed. These patches are excessive multiplication of lymphoid nodules within the lower portions of the small intestines.The occurrence of this abnormal cell division may prevent the linings of the intestines to perform its normal functions.

In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) w

aivan3 [116]

Answer:

The correct answers are:

The protein core is hydrophobic in nature.
Mutation disrupts the hydrophobic interactions between the non-polar amino acids in the core of the protein thereby destabilising its structure.
Filling the blanks: non-polar, hydrophobic, large, Van der Waals contacts, Van der Waals contacts.

Explanation:

The core of a protein is rich in non-polar amino acids like alanine, valine, leucine, etc.
These amino acids are capable of interacting with each other by the formation of weak Van der Waals contacts with each other.
Van der Waals forces can be defined as the force of attraction between atoms or molecules when they are in close vicinity with respect to each other.
The proper folding of a protein requires the proper positioning of each of the side chains of the amino acids in both the interior as well as the exterior of the protein.
Mutation causing the replacement of a short chain non-polar amino acid with a long-chain non polar amino acid in the protein core requires more space for the long chain non-polar amino acid. This disrupts many Van der Waal forces of interaction among other non-polar amino acid side chains in the interior of the protein.
This ultimately distorts the entire folding pattern of the protein causing its destabilisation and mis-folding.
