Answer:

Some of the hydrogen bonds with other elements, but most of it remains free hydrogen. Both hydrogen and helium are light elements, so they will tend to evaporate into space over time. ... But the gravity of Earth isn't strong enough, so Earth's early atmosphere of helium and free hydrogen evaporated into space.

Climate change
Greenhouse effect

Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.

These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.

Increasing carbon dioxide levels

Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.

Global warming

The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.

Novosadov [1.4K]

Answer:

Parents: Yellow (Aarr) and Grey (AaRr)

Explanation:

Given:

allele A = yellow

allele R = black,

Heteroozygous = gray

Genotypes of the parents:

yellow (Aarr) - female

gray (AaRr) - gray

cross between these

Parents: Yellow (Aarr)  and Grey (AaRr)

Gametes: (Ar, ar) and (AR, Ar, aR, ar)

F1 (Punnet square)

----|----- AR ------|------- Ar ------|------ aR -----|----- ar

Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)

ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)

Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
