A heterozygous tall pea plant is allowed to self-fertilize. The resulting F1 progeny are 25% homozygous tall, 50% heterozygous t
maks197457 [2]

Answer:

25% heterozygous tall

Explanation:

If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.

The first one for homozygous tall, then we have 100% AA.

The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.

The last one would be for dwarf, and we'll have 100%aa.

Adding all of them, we'll have

AA = 100 + 25 + 25 = 150%

Aa =  50+50 = 100%

aa = 100 + 25 + 25 = 150%

as we had 4 crosses, so dividing the total percentages by 4, we'll have,

AA = 37.5%

Aa = 25%

aa = 37.5%

:. The percentage of heterozygous tall would be 25%.

Hope it helps:)

The levels of carbon are expected to____ of our oceans
andreev551 [17]

Answer:

The levels of carbon are expected to_increase___ of our oceans

Explanation:

As humans activities increase the levels of carbon dioxide in the atmosphere so do the ocean levels of carbon increase. This is because of the fact that gases from the atmosphere dissolve in and out of the oceans at the interphase between the atmosphere and hydrosphere.

The more carbon dioxide in the atmosphere, the more the gas dissolves in the oceans. This is why more corals are bleaching around the world. The dissolved carbon dioxide is lowering the pH of the ocean waters because of the formation of more carbonic acid.
