Answer:
What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.
Explanation:
A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.
The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.
The mass of the star actually determines the stage of the
star after supernova. If the mass of the star is small, then it would become a
very small and dwarf, cold and dead body in space. The mass of the star has to
be less than that of the sun. If the mass of the star is greater than sun, then
it would become a black hole. The mass of the star has to be more than 1.4
times the mass of the sun to become a black hole.
Cell division and differentiation first begins during the germinal stage of prenatal development.
<u>Explanation:</u>
The development of the zygote into a full developed fetus occurs in three most prominent stages they are the germinal stage that occurs from the conception to the second week.
The embryonic stage that is from second week to the eighth week and the fetal stage that is from the eighth week till the birth of the baby. Each stage has its characteristic development that has to be completed.
Answer:
The longer the day, the longer the sun is exposure which can lead to increases in atmospheric temperature.
