Enzyme activity will be highest at its optimum temperature.
At temperatures far below the optimum, the enzyme does not possess enough energy to work (i.e. the molecules aren't moving fast enough because of the higher temperature to increase collisions). This is called the activation energy.
At high temperatures, the enzyme can become denatured, warping its shape and catalytic activity. This means its activity will drop quite quickly until it can no longer function.
The answer is C. This was
achieved through
gene regulatory networks. The ability of the cells
to segment and differentiate gave the
metazoans a great advantage. This is thought
to have begun in the Cambrian period with complete
bodies existing by the Paleozoic era.
Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
The answer have to be ( B )
Because in his book , " Origin of species " he doesn't mentioned anything about the origin of man kind. But only implied certain points , most likely about the evolutionary process :)
