Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources.

Answer: The correct answer is liquid.
Explanation:
Liquid, gas and solid are the states of the matter.
Solid: In the solid, the inter molecular force of attraction is strongest. The particles are more tightly packed in this in comparison to liquid and gas. It has definite shape and volume. For example, iron.
Gas: In the solid, the inter molecular force of attraction is very less. The particles are not tightly packed in this in comparison to solid and liquid. For example, hydrogen gas.
Liquid: In the liquid, the inter molecular force of attraction is not very strong. The particles are loosely packed. It has no definite shape but has definite volume. For example, water.
Therefore, water is an example of a liquid.
Answer:
True
Explanation:
Geneticists have discovered that all human embryos start life as females. In the early development in the embryonic stage, this is true both for humans and mammals. This changes only at the 2nd month (in the case of humans, since different mammals have different gestating periods) if the embryo can elaborate enough androgens (dominant male hormone) to offset the maternal estrogens (dominant female hormone) then, maleness develops.
Answer:
The most important abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.
