The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.
Answer:
The difference between weather and climate is that weather consists of the short-term (minutes to months) changes in the atmosphere. Most people think of weather in terms of temperature, humidity, precipitation, cloudiness, brightness, visibility, wind, and atmospheric pressure, as in high and low pressure

Answer:
Osteoporosis
Explanation:
Osteoporosis occurs when the bones become porous i.e less dense and weak. This can led to fracture of the bones because of the brittle nature of the bones. Deficiency in vitamin D as well as deficiency in calcium can result to osteoporosis in the elderly.
In the case of Marie, she is lactose intolerance, meaning she is most likely not to be consuming milk which contains a high quantity of calcium needed for bone development. So also, it was said she prefers staying indoors than going outside, meaning she has no access to sunlight which contains vitamin D. These factors could jointly influence the appearance of osteoporosis.
