4. The main action of EDCs is to block the synthesis of all natural hormones.

What defines an Endocrine Disrupting Chemical (EDC)?

1. An EDC is an exogenous agent that interferes with natural hormones responsible for homeostasis and development.
2. EDCs primarily disrupt endocrine glands by blocking the action of natural hormones.
3. EDCs only affect the production and release of natural hormones.
4. The primary mechanism of EDCs is to mimic the action of natural hormones.

1. Crop removal refers to the transfer of pesticides and their breakdown products away from the treatment site with harvested crops.
2. Crop removal describes the degradation of pesticides within the plant.
3. Crop removal is the process of pesticides leaching into the soil.
4. Crop removal involves the volatilization of pesticides from the plant surface.

Which term refers to the uptake of pesticides into a plant?

1. Absorption is the process by which pesticides are taken up into the plant.
2. Volatilization refers to pesticides entering a plant.
3. Degradation is the term for pesticides being taken up by plants.
4. Bioaccumulation describes the initial uptake of pesticides into a plant.

What process involves the downward movement of pesticides through the soil, facilitated by rainwater or irrigation water?

1. Leaching describes the downward movement of pesticides through the soil profile.
2. Absorption is the process of downward soil movement of pesticides.
3. Volatilization is the downward movement of pesticides in soil.
4. Runoff is the process of downward pesticide movement in soil.

Identify the process described by the physical transport of pesticides over the ground surface by rainwater.

1. Runoff is the term for the physical movement of pesticides across the ground surface due to rainwater.
2. Leaching is the process of pesticides moving over the ground surface with rainwater.
3. Volatilization describes the surface movement of pesticides by rainwater.
4. Absorption is the physical transport of pesticides over the ground by rainwater.

How can pesticides be transported over long distances as particles?

1. Pesticides can be carried long distances by adsorbing onto dust particles in the air.
2. Pesticides primarily travel long distances by dissolving in rainwater.
3. Long-distance transport occurs mainly through absorption into plant tissues.
4. Pesticides are transported long distances through microbial degradation.

What factor significantly influences the volatilization of pesticides?

1. The vapor pressure of the pesticide compounds is a key determinant of volatilization.
2. The color of the pesticide does not affect its volatilization rate.
3. The solubility of the pesticide in water is the primary factor influencing volatilization.
4. The density of the pesticide is the main driver of volatilization.

Which of the following processes describes the movement of pesticides from the plant surface, water, or soil into the air?
