Floods affect the environment by destroying building, creating areas of more fertile soil and speeding up the weathering of rock.
Answer: Option A,B & C

Answer:
I.
4) The deoxygenated blood then travels through the veins and enters the right side of the heart.
1) The blood leaves the heart through the aorta.
2) The blood travels throughout the body via the arteries to the capillaries.
3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.
II.
2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.
1) The deoxygenated blood flows from the right side of the heart to go to the lungs.
3) The oxygenated blood then returns to the left side of the heart.
Explanation:
Both have phosphate-pentose back bone, as well as both have adenine, cytosine and guanine bases.
Answer:
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection
