The sodium-potassium pump <span>is one major cause for the resting potential of a neuron's membrane.
Hence,

A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women. In children, the threshold for high red blood cell count varies with age and sex.
Answer:
a. do not immediately increase in number when placed in a culture
Explanation:
When bacteria placed in a new culture it shows a pattern of growth which is known as sigmoid growth. It has four phases lag, log, stationary, and death.
The lag phase occurs because bacteria do not start dividing immediately just after the placed in the new culture media because bacteria first adapt to the new environment and prepare enzymes needed for metabolizing the new substrate.
As the bacteria pass this lag phase it starts to divide at an exponential rate. Therefore it is true that most bacteria do not increase in number immediately after placed in a new culture.
Active transport requires energy, whereas passive doesn't.
Both Endocytosis and Exocytosis are transports that require energy from the cell in order to transport particles. Therefore, they're forms of active transport.
