Answer:
The atmosphere will contain more oxygen, resulting in warmer global temperatures.
Explanation:
I did this on my test
Answer:
C. ATP is required to move substance A into the cell.
Explanation:
As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".
This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.
<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>
Hence, the correct answer is "C. ATP is required to move substance A into the cell."
Explanation:
Temprature:the body must maintain a relatively constant temperature if it gets to hot the body employees vasodilation to cool down this delites the blood vessels allowing more heat to escape from them through the skin
Glucose: the body must regulate glucose levels to stay healthy. When glucose levels become to high the body realeases a hormone called an insulinwhen they become to low the body converts the glocogenin the blood to glucose
Toxins :in the blood can distrupt the body's homeostasis thus it signals the urinary system to ensure that the toxins are excreated
