2. In polar regions, phytoplankton.
natka813 [3]

Answer:

b. thrive during the summer, when sunlight increases

Explanation:

Phytoplankton production is highly associated with latitude and season. In polar regions, phytoplankton production is reduced to the summer (and eventually spring) season. In consequence, the zooplankton that eats phytoplankton only can survive during the spring and summer seasons. On the other hand, in tropical areas, there exists a nearly constant phytoplankton production all year round.

Water, H2O, and methane, CH4, are both covalent substances. Why is water a liquid at room temperature while methane is a gas? A
tino4ka555 [31]

The right answer is D.

Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.

The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).

Lera25 [3.4K]

Answer:

a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.

Explanation:

Pesticides are chemical substances used to get rid of or kill pests that attack crops on farmlands. These pesticides, although help the farmer to get rid of his pest problem and likely have an increase in yield, are dangerous to human and animal health if consumed.

As set up by the Environmental Protection Agency (EPA), pesticide tolerance is the amount or quantity of pesticide chemical that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
