Explanation:

Animals takes oxygen inside their body from the environment and exchange of gases occurs in the organ such lungs where the cells loaded itself with oxygen and removed the carbondioxide from the cell. When the organism exhaled carbondioxide gas is released in the environment. Food is broken down in the digestive tract and nutrients is absorbed from small intestine which adds these nutrients into blood that is used by the cells. Kidney filters the blood and removes the nitrogenous waste and excess amount of water from the blood. This urine is removed with the excretory system of the body.

If you cross two organisms that are heterozygous for a trait, what percent of
brilliants [131]

Answer:

25%

Explanation:

Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
