which of the following structures allow materials to be exchanged easily with cells? arteries atria veins capillaries

abruzzese [7]

Atria is a large part of the heart so too big for cells; arteries & veins lead away or to the heart.
Capillaries are the smallest vascular structures that allow materials to be exchanged easily between cells.

A template strand of DNA contains nucleotides in the following proportions: 14% adenine

MAXImum [283]

Answer:

The proportions of nucleotides in the newly formed complimentary strand will be:

14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).

Explanation:

In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.

Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).

So, the complimentary strand must have

thymine equal to the amount of adenine in template strand.
adenine equal to the amount of thymine in template strand.
guanine equal to the amount of cytosine in template strand.
cytosine equal to the amount of guanine in template strand.

2. Most mutations are "silent." What does this mean?

Zielflug [23.3K]

Explanation:

Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM
