Answer:

In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.

Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

svlad2 [7]

Answer:

No

Explanation:

Both A alleles and B alleles are dominant over the O alleles. This means that both parents must have an O allele present to even have a chance of having a child with type O blood. Lets say the mother has type O blood with the father having type AB blood. The possible combination would be: AO, BO, AO, BO. The punnett square should look like this:

        A          B

O     AO        BO

O     AO        BO

Mutation is a random and non-adaptive process. This was first proven by:
s2008m [1.1K]

Answer:

Option (d).

Explanation:

Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.

Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.

Thus, the correct answer is option (d).

Muscles that move the eyeball have ________ fibers.
ozzi

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.

<h3>What are fast muscle fibers?</h3>

Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.

Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.

Therefore, the correct option is A.
