It should be B because when people breath in it is oxygen and when we breath out it is carbon dioxide
Answer:
The answer is higher.
Explanation:
ADH which stands for Antidiruetic Hormone is a hormone procuded by the hypothalamus in our brains and helps our kidneys save the water in the body in certain situations.
The example given in the question states that the person has not been drinking water during the three mile run, which indicates a lack of water and also the loss of water by means of sweating during the running process. These would result in a much higher level of ADH in the bloodstream due to the body trying to hold onto the liquid that remains in the body to cover for the loss and lack of water.
I hope this answer helps.
Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
