Answer:
d
Explanation:
assuming you mean moves not movies, the rainforest has the most moisture so itll have the most precipitation
The energy required to drive nutrient cycling is obtained by processes occurring in the biosphere. The primary source of energy for ecosystem processes is photosynthesis. Directly or indirectly, photosynthesis provides the energy for all forms of life in the biosphere. Photosynthesis utilizes energy from the sun to reduce CO2<span> into high energy organic compounds. Subsequently, the energy contained in these organic compounds is released by the process of respiration. The respiration process releases energy by oxidizing the high energy bonds of the organic compounds, the energy released being used to perform all the metabolic processes of biota.

Answer:
The genes are linked, and the arrangement is coupled (one homolog has both dominant alleles; the other homolog has both recessive alleles).
RY
/
ry
Explanation:
R_= colored aleurone
rr= colorless aeurone
Y_= green plant
yy= yellow plant
They do a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits (yr/yr) the following F1 is obtained:
- 88 Colored, green (RY/ry)
- 92 colorless, yellow (ry/ry)
- 8 colorless, green (rY/ry)
- 12 colored, yellow (Ry/ry)
If the genes assorted independently, all of the possible offspring phenotypes would appear in the same frequency. However, they obtained 2 phenotypes much more abundant that the other two. Since recombination is a rare event during crossing over, when two genes are linked the recombinant gametes are produced less frequently than the parentals.
We can propose that the phenotypes Colored, green (RY) and colorless yellow (ry) are the parental gametes, and the unknown plant has the arrangement RY/ry, with both genes linked.
