Answer:
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Explanation:
Answer:
1/8
Explanation:
An individual must have all three dominant alleles to be red, in homozygosis or heterozygosis (R_E_D_).
<u>The parental cross was:</u>
RREEDD x rreedd
F1: RrEeDd
<u>The test cross</u> is between the RrEeDd indiviudals and homozygous recessive rreedd.
The genes assort independently, so we can use Mendel's law of segregation to predict separately for each gene the proportion of the offspring that will have the dominant alleles.
<h3><u>Rr x rr</u></h3>
1/2 Rr
1/2 rr
<h3><u>Ee x ee</u></h3>
1/2 Ee
1/2 ee
<h3><u>Dd x dd</u></h3>
1/2 Dd
1/2 dd
Genes are independent, so the probability of having a R_E_D_ offpsring is calculated by multiplying the individual probabilities of having a dominant allele for each gene:
1/2 (Rr) × 1/2 (Ee) × 1/2 (Dd)= 1/8
Klay does not have to worry about anything blowing up or inhailing harmful gases.

Increased levels of CO2 make the ocean more acidic and put sea organisms in danger. ... This could mean slower growth in the world's corals reefs, which are already stressed and dying from the warmer ocean temperatures associated with increased greenhouse gases in the atmosphere.
