A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.

Answer:

A mutation is a change in a DNA sequence introduced approximately either via a mistake made when the DNA is copied or through chemical damage. Regions of the genome (referred to as genes) provide commands for the introduction of protein molecules, which perform maximum of the important jobs in cells. Certain styles of mutations are silent and haven't any effect, but others affect protein production in a number of ways.

Which term best describes the difference in colors of the birds below?
NeX [460]

Answer:

<u><em>The correct option is C) genetic variation</em></u>

Explanation:

Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.

As the birds show different variations hence the term that best described them is genetic variation.

Impulses originating in the part of the brain called the medulla would most directly affect which body structure?
gtnhenbr [62]

The question is incomplete. The complete question is:

Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?

a. A leg muscle

b. A ligament

c. An arm bone

d. The heart

Answer:

d. The heart

Explanation:

The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.

For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.

One method for separating polypeptides makes use of their different solubilities. The solubility of large polypeptides in water
Naddika [18.5K]

Answer:

The solubility of any substance in water depends on its polarity. The polar molecule dissolves more easily in the water than the non polar molecule. Amino acids have different polarity at different pH.

(a) (Lys-Ala)3 : The (Lys-Ala)3 contain more positive charge and highly polar the at pH 7 as compared with the  (Gly)20 that remains uncharged and has less polarity.

(b) (Glu)20 :This amino acids negatively charged at pH 7 and highly polar than the (Phe-Met)3 which is non polar or less polar and hence least soluble  in water.

(c) (Asn-Ser-His)5 is highly polar at pH 3 as compared with the (Ala-Asp-Gly)5 that contains the carboxylate groups of Asp residues that are partially neutral. The  (Asn-Ser-His)5 contains = the imidazole groups of His residues are fully polar and soluble in water.

(d) (Asn-Ser-His)5 is polar at pH 6.0 because both have polar side chains Ser but (Asn-Ser-His)5 is only partially partially protonated due to the His side chains. Thus,  (Asn-Ser-His)5 is more soluble in water.
