Answer:
The fourth plant that receives pure water is the control group.
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>
mitosis , a part of asexual reproduction because it produces diploids is the correct answer
Answer:
My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.
Answer:
increases; protein denaturation occurs
Explanation:
One of the characteristic of enzymes is the sensitivity to temperature .
Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.
However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.
At temperature above the optimum,the high temperature breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be denatured
