When blood supplies oxygen and food to a cell surface and these molecules diffuse across, we might expect some "resting time." H
owever, if we inspected most cell membranes in a living human body, we would find a nearly continuous flow of substances back-and-forth across the plasma membrane. Which of the following is not a reason why? a) Cell metabolism is constantly using up oxygen and raw materials; this lowers their concentration so more will diffuse into the cell. b) Cell metabolism is constantly producing waste molecules; this increases their concentration so more will diffuse out of the cell. c) Cells produce useful secretions; this increases their concentration and more will diffuse out of the cell. d) Cell metabolism constantly produces carbon dioxide in respiration; this increases its concentration so more will diffuse out of the cell. e) Cells are living entities and in order to live can never "rest".
Blood is the main connective tissue of the body. Blood helps in the transport of oxygen, nutrients and the excretory product of the body. Blood also provides immunity as it contains white blood cells.
The resting time is expected during the diffusion process. But the substance continuous back and forth in the body. This is because cells are the main living entity of the organism. The cells are never at rest in order to live and their resting time is not possible.
There are two ways to continuously keep providing energy to the muscles in the body. The body uses the aerobic pathway where the glucose is used to make the ATP to provide energy to the muscle cells. If the store of ATP gets reduced, the body triggers homoeostasis mechanism involving the anaerobic pathway. In this pathway, glucose is converted into lactate in the muscles tissues. This lactate is used to make ATP that is used by the muscle cells. This way the body ensures that the supply of energy is maintained throughout the run.
Bone marrow aspiration symptom alerts the health care provider that this child might have acute lymphoblastic leukemia (all)
Acute lymphocytic leukemia (ALL) is a kind of blood and bone marrow malignancy. Blood cells are generated in the spongy tissue inside the bones.
Acute lymphocytic leukemia gets its name from the fact that it advances quickly and produces immature blood cells rather than mature ones.
Acute lymphoblastic leukemia in children is more frequent than other cancers, however it is curable in a significant portion of cases. Adult survival rates are lower, although they are rising.
ALL has a 5-year relative survival rate of 68.8%. 90 percent of children and 30 to 40 percent of adults are included in the statistics, respectively.
if you are talking about both then the first when measures the meters in a high tide and a low tide and the bottom one shows how it has been increasingly rising and lowering
