An osteocyte, a star-shaped type of bone cell, is the most commonly found cell in mature bone tissue, and can live as long as the organism itself.[1] The adult human body has about 42 billion osteocytes.[2] Osteocytes have an average half life of 25 years, they do not divide, and they are derived from osteoprogenitors, some of which differentiate ...
A: According to the Infoplease website from Pearson Education, the biological importance of osmosis is that it facilitates the distribution of essential nutrients in the body and the excretion of metabolic waste products. Cells have semipermeable membranes, and osmosis makes it possible for liquid solvents to pass through these cell membranes.
The movement of water by osmosis is the main reason why it is so important to control the water balance of the body. Active transport uses energy to move substances against (up) a concentration gradient or across a partially permeable membrane.ubstances are moving in and out of the cells of your body all the time. To understand why the water balance is so important in homeostasis, and to make sense of how your kidneys work, you need to know about diffusion, osmosis and active transport.
