Answer:

B. CO2 out

Explanation:

The excretion is the process of removal of the waste product from the body. The carbon dioxide is the byproduct of the aerobic respiration, which is carries from the tissues and the lungs by blood. In the lungs at alveoli, the carbon dioxide is transferred from the blood to the lungs and released out through the nostrils. Hence, the out of the carbon dioxide represent excretion through lungs.

Explain how the population of rock pocket mice changed fur color over time.
Lorico [155]

Answer:

Most genes are identical, but dark and light rock pocket mice differ in one gene (Mc1r; 4:55). Data from Data Set 2 show that a mouse's genotype for the MC1R gene affects their fur color. Mice with two copies of allele 2 have the darkest fur.

The variation of kernel color in corn plants is an inherited trait. R is the dominant allele for red kernels in a corn plant and
Hoochie [10]
The answer is 1/2.

If:
R - t<span>he dominant allele for red kernels
r - t</span><span>he recessive allele for yellow kernels

Then:
RR - dominant homozygote
Rr - heterozygote
rr - recessive homozygote

The cross Rr x rr will result in 1/2 of offspring with red kernels (Rr) and 1/2 of offspring with yellow kernels (rr):
Parental generation:      Rr      x      rr
Offspring generation:  Rr    Rr     rr      rr
So, there are 2 out of 4 Rr offspring (2/4 = 1/2) and 2 out of 4 rr offspring (2/4 = 1/2).</span>

Yakvenalex [24]

Answer:

Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects.
