Shorts Answer Question​

Answer 1

Answer:

1:When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air.

2:Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle

3:The male frog grabs the female's back and fertilizes the eggs as the female frog releases them

4:The main difference between oviparous and viviparous animals is that oviparous animals do no undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother

5: don't know

Answer 2

Explanation:

1)When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

2)Carbon dioxide gas does not support combustion. It displaces oxygen so that oxygen cannot come in contact with fire. Thus, carbon dioxide gas stops the supply of oxygen thereby removing oxygen from the fire triangle. In fire extinguishers, carbon dioxide gas is stored under very high pressure.

3)In most species of frogs, fertilization is external. The male frog grabs the female's back and fertilizes the eggs as the female frog releases them (Figure 2.2B). ... The egg pronucleus and the sperm pronucleus will meet in the egg cytoplasm to form the diploid zygotic nucleus.

4) The main difference between oviparous and viviparous animals is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother. ... In contrast, viviparous animals are born as live young individuals. Therefore, they do not lay eggs.

5)If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation. The average menstrual cycle lasts 28 days. The cycle starts with the first day of one period and ends with the first day of the next period.
