2. consider an organism that has two pairs of homologous chromosomes in each of its diploid (2n) somatic cells. how many chromosomes would the organism’s cell have during each of the following stages?

what is the aerea shown

explanation:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
