A silent mutation. This is when the new codon will work just as well as the old one without changing the amino acid shape.

The colon is divided into two sections called the ascending transverse and descending transverse. True False

inn [45]

According to the research, the correct option is false. The colon can be divided into four sections: ascending, transverse, descending and sigmoid.

<h3>What is the colon?</h3>

It refers to the portion of the large intestine, whose function is to convert digested food waste (chyme).

It can be divided into four sections:

Ascending, it begins at the junction with the tenuous intestine and extends down the right side of the abdomen.

Transverse, which crosses the abdomen from the right side to the left.

Descending

Sigmoid.

Therefore, we can conclude that according to the research, the correct option is false. The colon can be divided into four sections: ascending, transverse, descending and sigmoid.

Matings between individuals from the two populations of Rhagoletis produce hybrid flies that appear to be healthy and have norma

Mama L [17]

<h2>The correct answer is : C.</h2>

Explanation:

According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.
