Answer:

Potassium

Explanation:

Resting membrane potential may be defines as the voltage or charge difference between inside and outside of the cell when the cell is at rest. The resting membrane potential of the cell is -70mV.

Potassium ion channels are leaky channels that are always open and can move into and out of the cell. The potassium ions are responsible for setting of the resting membrane potential of the cell. Inward movement of sodium ions may disrupt the resting membrane potential of the cell.

Thus, the correct answer is option (B).

Answer:

The answer is B, How does gravitropism affect plant growth?

Explanation:

According to Google:

"Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it."

So, since the students put the pots on their sides, and they say that the bean plants bend upwards, then option B is the only logical explanation for the plants' behavior.

Aleks [24]
The correct answer is A.
The use of antibacterial drugs can cause modifications in the genetic material of the concerned bacteria. If the genetic material of the bacteria are modify, that means they have undergone mutation. Because the base sequence of the normal and that of the mutated gene is different, antibiotic will not be able to recognize the bacteria again and thus will not be able to attack it.
