Answer:
C.Cells develop in particular areas of the body, which gives them the same functions
Explanation:
Cell differentiation is the process of cells becoming specialized as their body develops. ... Through the action of these transcription factors, cells specialize into one of hundreds of different cell types in the human body.Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions
I believe is osmosis, diffusion, and cell transport. Not sure let somebody else answer that to see if I'm correct
William Harvey was the first to describe systemic circulation
Answer:
a. add more of the enzyme.
Explanation:
Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.
Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.
