Answer:
I'm pretty sure the answer is A. Once non-renewable resources are used, they are gone and can't be replaced
I would say water, animals and plant

To balance out negative charges on the interior of the membrane, voltage-gated sodium channels open, allowing sodium ions to enter the cell.
There are two factors that draw sodium ions (Na+) to the inside of neurons while they are at rest. The (Na+) ion is pushed into the cell down the concentration gradient by the high concentration of (Na+) outside the cell. Similar to how the positively charged (Na+) inside the neuron is drawn in by the electrostatic pressure caused by the negative charge inside.
Which of the four ion channel types are they? Ion channels that are voltage-gated, Linguistic-gated ion channels (also known as ionotropic receptors), ion channels with light-gated, Ion channels with mechanosensitivity, Nucleotide-gated ion channels that cycle, and Ion channels that are calcium-gated.

Answer:
this process creates mutation in a cell"s DNA sequence that leads to an increased variation in the gene pool.
Answer:
Ethylene gas
Explanation:
The gas is produced in trace amount by plants (virtually every part of the plant is capable of producing ethylene because it is a gas and it diffuses) and has an effect on plants. Ethylene gas is responsible for ripening of fruits, opening up of flowers and senescence and abscission of leaves. Also, when one puts a ripening fruit among unripe fruits, the unripe ones will ripen in a matter of days – because the ripe one produces ethylene gas which has en effect on the others. Commercially, farmers harvest fully developed bu unripe fruits and then expose them to ethylene gas to ripen when they reach the market. This alleviates food spoilage in transit.
