What's average temperature for a city fir a year
victus00 [196]

Answer:  

Average annual temperature in US cities would range between 50-70 degrees Fahrenheit  

Explanation:  

There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.

Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:

Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

b) Replacement of a polar amino acid with another polar amino acid at the protein's surface

c) Replacement of a polar amino acid with another polar amino acid in the protein's interior

d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
