How does water move from the biosphere to the atmosphere in the water cycle
Ludmilka [50]

Answer:

The water cycle depicts the ongoing circulation of water inside the Earth and atmosphere. It is a complicated structure with several functions. Water vapor evaporates from liquid water, compresses to create clouds, and falls back to earth as rain and snow.

Explanation:

<em>The water cycle is a cyclical process in which water circulates between the earth's atmosphere, seas, and surface via precipitation, drainage in lakes and rivers, and return to the earth's atmosphere by absorption and evaporation. Throughout respiration, organisms exhale carbon dioxide and water vapor, which evaporates back into the atmosphere.</em>

A breeder wants to set up a program to produce zebrafish with long fins. Having long fins is a dominant trait compared to the sh
lions [1.4K]

Answer:

Option C

Explanation:

Let the allele for long fin trait be "L" and the allele for short fin trait be "l"

Given L is dominant over l

If he crosses a long fish and short fin to produce three fourth long fins and one fourth short fins, it is not confirmed that the long fin species are homozygous as represented in the cross below

Ll * Ll

LL, Ll. Ll, ll

The two parent species are long (but not homozygous). Hence, option A is incorrect

However, if this test cross is carried out several times, the recessive trait may disappear thereby producing only homozygous long finned species.

Hence, option C is correct
