Answer:
Crossing over is somewhat randomly distributed over the length of the chromosome.
Two loci that are far apart are more likely to have a crossover between them than two loci that are close together.
Explanation:
Crossing over is the process of exchange of genetic material between two non-sister chromatids of homologous chromosomes. It occurs during pachytene of prophase I of meiosis I. The frequency of crossing over depends on distance between two genes present on same chromosomes. On the same chromosome, the distantly located genes are more likely to exhibit crossing over than the closely located genes.
To make amino acids, proteins, and DNA. When organisms die, their bodies decompose bringing nitrogen into the soil on land or into ocean water.
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
so therefore the answer is a,b,and c
I think it's C but i may be wrong
