In the earth’s layers, why is the outer core in the state of a liquid and the inner core in the state of a solid?

a. the temperature of the core will not allow either part to be solid.

b. the outer core is hotter that an inner core which makes the material liquid.

c. the composition of the outer layer is made up of material that has a lower melting point

d. the pressure applied to the inner core causes it to be solid even though it is hotter than the outer core.

(( this is science))

d

Explanation:

the high pressure causes the inner core to be solid  but the outer core doesn't have much pressure applied to it

The genotype of male rabbit is BbRr and female rabbit is bbrr.

Gametes produced by the male rabbit are BR, bR, Br, br. Gametes produced by the female rabbit is br.

The rabbits do have a variety of fur colour, while of them the black is the dominant one and the white is the recessive one. So denoting the gene of the fur colour of the rabbit by B,

The dominant colour black is B and the recessive colour white is b.

Rabbits do have a variety of eye colour as well. While the Black colour is dominant again, the red is the recessive.

So, denoting the gene for the eye colour by R,

The dominant eye colour black be R and the recessive eye colour red is r.

Thus, the genotype of male rabbit is BbRr and female rabbit is bbrr.

Therefore, gametes produced by the male rabbit are BR, bR, Br and br, whereas the gametes produced by the female rabbit is br only.
