KIM [24]

As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those Located near the heart, because they are absorbing the most shock.

Explanation:

When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

uysha [10]

Answer:

C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Explanation:

Assuming the black genotype is BB and the brown genotype is bb.

At F1:

BB x bb = All Bb (black)

At F2:

Bb x Bb = BB (black), 2Bb (Black), bb (brown)

Th ratio of black to brown is 3:1

961 black : 317 brown is approximately 3:1.

Hence, the correct option is C.

An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele
