Answer:

Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Scientists group materials together ____________ it is easier to compare and study them that way.

A however

B but

C although

D because

Answer:

The correct answer is - option D because.

Explanation:

Researcher and scientists tries to group material together on their similarities and difference to one another which makes it easier to study and compare various type of materials.

It is the one of major reasons to differentiate materials between groups like liquids state, gases state,  plasma state and solid state materials. One can easily see the difference and comparison is very clear on this type of grouping of materials.

Thus, the correct answer is - option D.

Explain why it is impossible for a man to be a carrier of a sex-linked trait.
hoa [83]

Answer:

Because it contains two different sex chromosomes

Explanation:

Man in its genome contains two sex chromosomes, X and Y, while woman contains two X chromosomes.

In order to be a carrier of a sex-linked trait, a person should have one copy (one allele) of a certain trait. For example, if a female has one X chromosome with mutation (e.g. disease carrying) and one normal X chromosome, she is carrier for the disease. But, on the other hand if a male has one X chromosome with mutation he will develop that disease.
