The basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
Price of photosynthesis will increase as the quantity of collisions between enzymes and substrate will increase. this is the top-quality temperature. The enzymes begin to denature, so the fee of photosynthesis decreases.
Increase in enzyme attention will growth the charge of photosynthetic and respiratory reactions, furnished that there are substrates available to bind to. once all substrate is bound by enzymes, the reactions, the response will no longer increase, since there may be not anything for extra enzymes to bind to.
Enzymes are proteins that catalyze, or affect the fee, of chemical reactions without themselves being altered inside the process. precise enzymes catalyze every mobile reaction. the main position of enzymes at some point of the respiratory reaction is to help in transferring electrons from one molecule to some other.

Stem cell therapies are not new. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued.
The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. Political leaders began to debate over how to regulate and fund research involving human embryonic stem (hES) cells.
Newer breakthroughs may bring this debate to an end. In 2006 scientists learned how to stimulate a patient's own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.
Answer:
Iron deficiency anemia.
Explanation:
The presence of blood in her stool does not affect blood volume, but leads to iron deficiency anemia when iron stores are depleted.
Iron deficiency anemia is a common type of anemia, a condition in which the blood does not have enough healthy red blood cells. It is due to a lack of iron, so the body cannot produce a sufficient amount of hemoglobin, a substance present in red blood cells that allows them to transport oxygen. As a consequence, iron deficiency anemia can make you feel tired and short of breath.
