Answer:
Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.
Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.
Explanation:
1. Reduces the chromosome number from diploid to haploid
2. Ensures that each of the 4 gametes has a complete set of chromosomes
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
Combustion of fossil fuels release massive amounts of carbon dioxide
I am sure 100%
Good luck
