Answer: True

Explanation: Ion channels are very specific and are voltage gated channels. They are highly specific and selective for particular ions only.

Example: Some of the channels allow the flow of potassium ions but do not allow sodium ions to cross the membrane to maintain the concentration.

Some of the positive ion channels allow only the movement of positive ions and no negative ions. These channels are not always open and opens only when there is a concentration gradient.

Technology can have good and bad effects. What is a bad effect of spraying pesticides on crops with the use of airplanes?

Anastaziya [24]

The correct answer is option a, that is, It is sometimes sprayed too far from the crops.

The use of pesticides on crops may exhibit a significant threat to the environment, mainly in and nearby to water sources with sensitive ecosystems, sources area, public drinking water, residential areas, and recreational waters.

Aircraft spray of pesticides takes place from a greater altitude than the ground-based equipment and on a major scale, both of these elements may enhance the threat of spray drift.
