Which variable is likely to undergo the largest change in value resulting from a mutation that introduces a new allele into a po
dsp73

Answer:

b. average heterozygosity

Explanation:

From the available options:

a. nucleotide variability

b. average heterozygosity

c. average number of loci

d. geographic variability

Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.

The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.

Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.

Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.

When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.

<em>The correct option is b.</em>

tructures used in recombinant DNA technology to carry the DNA from the cells of one species to the cells of another species are
Kobotan [32]

The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.

When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.

Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).

The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.

Mole ends=2x(moles DNA)x number of restriction sites.

The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.

Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].

The bolus is liquefied in the ________ and it is now called chyme.
Strike441 [17]

Answer:

The options:

A) esophagus

B) stomach

C) small intestine

D) mouth

The CORRECT ANSWER IS B)

B) stomach

Explanation:

The digestive tract — often termed the gastrointestinal tract or alimentary canal — supplies the route via which foods passes through the body. In the course of this pathway, foods are digested into its constituents nutrients necessarily for absorption.

Digestion initially starts in the mouth, with enzymes in saliva dissolving carbohydrate (starch). In the course of chewing, the food is lubricated, a little bit of hear is used up, and less difficult to swallow and digest. The teeth and mouth aid conversion of each morsel of food to a bolus which flows right into the esophagus (“gullet”). In the course of chewing, taste buds stationed in the mouth gives pleasure to every mouthful — or to taste if not okay. Once the bolus is swallowed, it flows through the esophagus, it is kind of warmed and lubricated as it flows into the stomach.

Note:

The acidic condition of the STOMACH and the effect of gastric enzymes turns the bolus to CHYME, A LIQUEFIED MASS that is moved from the stomach to the small intestine.

What are your thoughts about how the universe formed?
V125BC [204]

 For centuries scientists thought the Universe always existed in a largely unchanged form, run like clockwork thanks to the laws of physics. But a Belgian priest and scientist called George Lemaitre put forward another idea. In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today.

His idea went largely unnoticed. But in 1929 astronomer Edwin Hubble discovered that the Universe isn’t static but is in fact expanding. If so, some scientists reasoned that if you rewound the Universe's life then at some point it should have existed as a tiny, dense point. Critics dismissed this: the celebrated astronomer Fred Hoyle sarcastically called this concept the “Big Bang Theory"
