Aerobic respiration<span>, a process that uses oxygen, and </span>anaerobic respiration, a process thatdoesn't<span> use oxygen, are two forms of cellular respiration. Although some cells may engage in just one type of respiration, most cells use both types, depending on an organism's needs. Cellular respiration also occurs outside of macro-organisms, as chemical processes — for example, in fermentation. In general, respiration is used to eliminate waste products and generate energy.</span>
Answer: i don`t know that much but
Explanation: if the magnetic field of the earth is decreasing year by year at one point it would be so weak that everything on earth would float here and there. the ocean of the earth would also float and as the ocean is one third of the earth the most of the earth would be covered in just floating water.

It is increased in great number since the 1960s which helps elderly people of the US to cover all the expenses they spend on their health issues and diseases.
Cell division is the process essential for growth and repair in multi-cellular organisms.
Injury to the tissue can activate surrounding cells to undergo cell division with the help of mitogens. Mitogens are the chemical substances which help in escalating mitotic divisions in the cells.
They act by activating the signal-transduction pathway which involve mitogen-activated protein kinase (MAPK).
Other possible manner could be the loss of density which could lead to the inactivation of contact inhibition. As there is a loss of cells during the injury, it makes an empty space which could also trigger or activate surrounding cell to start cell division.
In addition, at injury site the flow of blood also increases to transport various nutrients, clotting factors, growth factors etc. These increased nutrition and growth factors also speed up the process of mitosis.
<span>The site active of the enzyme bins the substrate to form the complex enzyme-substrate to start a specific chemical reaction. The site active of the enzyme has to fit exactly the shape of the substrate to trigger the catalysis.</span>
