mezya [45]

Options for the question are not given. They are as follows :

A. Mate them and see what color the offspring are—that will be the dominant color

B. Mate them and see what color the offspring are—the other will be the dominant color

C. Mate them, and then mate their offspring to see what color the next generation is

D. Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color

Answer:

A. Mate them and see what color the offspring are—that will be the dominant color

Explanation:

Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.

When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.

Licemer1 [7]

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y
