Answer:
Trees remove carbon dioxide from the atmosphere. Carbon dioxide is a greenhouse gas that causes global warming.
Explanation:
Trees take in carbon dioxide and release oxygen. Deforestation gets rid of trees, so carbon dioxide is no longer being absorbed. Since carbon dioxide is a greenhouse gas, meaning that it traps heat in the Earth's atmosphere, too much of it causes global temperatures to rise.

1:4 children will be albino.
If you make a Punnett square with Aa and Aa, you'll see that the ratios are:
AA:Aa:aa=1:2:1
so the ratio of aa out of the total is 1/(1+2+1)=1/4
The answers are:
- They are formed above Earth's surface - sedimentary rock.
- They form in Earth's crust or mantle - intrusive igneous rock.
- They are solid at room temperature - both.
- They are made of molten rocks called magma - intrusive igneous rock.
- They are made of weathered pieces of rock - sedimentary rock.
- They have a diverse composition. They may contain many types of minerals - both.
The fact that monotremes, such as the platypus, lay eggs "indicates that they are more closely related to reptiles than to other mammals".
<u>Option: D</u>
<u>Explanation:</u>
The explanation that unusual, egg-laying mammals still exist today might be because of their descendants have taken to the water. The oviparous mammals, the word itself suggest something unique — the monotremes, such as the platypus, understood as eccentric relatives of the majority of the mammals that carry young living.
Other traits, apart from laying eggs, make them look more like reptiles than our family. They have a reptilian gait with legs on the sides instead of under the body, and a single opening for urine, feces and sex instead of multiple outlets.
