Answer:
the atp molecule
Explanation:
lol i just copied the other person i need points to ask a math question
Hemoglobin is an important component of red blood cells that functions in transporting majority of oxygen in the body. One hemoglobin can bind to up to four oxygen molecules because of its four subunits. If the oxygen carrying ability of hemoglobin is decreased, carbon dioxide and temperature will increase and pH will decrease.
A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism. Plants also exhibit phototropism, or growing toward a light source. This response is controlled by a plant growth hormone called auxin.
Answer:
D. a solution containing a high concentration of solute
Explanation:
Water alongside solutes tends to naturally move in the environment i.e. to and fro a cell. This movement is achieved when an osmotic gradient is formed during OSMOSIS. Osmosis is the movement of water from a region of low concentration of solute (high concentration of water) to a region of high concentration of solute (low concentration of water) through a semi-permeable membrane (usually the plasma membrane).
The difference in solution concentration between a cell and its external environment creates the OSMOTIC gradient. Water moves until an equilibrium is achieved in both the cell and environment.
Red and White blood cells:
These are produced by the stem cells in the bone marrow. There are two types of stem cells for producing white blood cells - Myeloid stem cells (producing phagocytes such as neutrophils and monocytes - the undeveloped version of macrophages) and Lymphoid stem cells (responsible for production of lymphocytes such as B and T cells).
