A population of ground mice consist of 500 individuals. You are interested in the gene that codes for for a color and find out t
Lelechka [254]

Answer:

0,58

Explanation:

Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).

Which statement best explains how the rock shown in this photo was deformed​
meriva

Answer:

B. Stress caused by forces that stretch an area of the crust made the rock to break

Explanation:

From the picture inserted to this problem, we see a unit that has been severely fractured.

Fracturing results from the brittle deformation of a rock under applied stress.

  • Rock fracturing results in the formation of joints and faults.
  • We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
  • Also, a prominent fault which resembles an extensional fault can also be seen.
  • Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
