Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
After 12 hours without eating, Seth is very hungry. It is likely that Seth's blood glucose level is LOW and his blood insulin level is HIGH.
A situation in which the blood glucose level is low is called hypoglycemia. In this situation, the level of glucose in the blood is much more lower than the normal level. This may be caused by a lot of factors. When the blood glucose level is low, the glucagon hormone mobilize the liver to release glycogen which is converted to glucose. The presence of glucose in the blood increase the level of insulin secretion which in turn increased the feeling of hunger in the individual.
Evolution over millions of years, This could happen due to selection pressures like predators, change in environments for example the industrial revolution and how black moths were more in favor than white moths because the could blend in with the soot, natural selection also can cause this as well as bottleneck effect and genetic drift.
There were new crops; tools and farming methods, which helped, increase food production. These changes meant less death to smaller colonies, and overall improve the state of living. They now could live longer and have better sanitation compared to the earlier imperialism.
Hi! Can you please make your question clearer ?
