Answer:
The PH at which an enzyme will function best is;
In the optimal range
Explanation:
Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the enzyme is observed, which is known as its optimal pH
When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops
This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate
The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5
Answer:
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism.
Explanation:
Answer: D. Guns happened to be in the room.
Explanation: In studying different concepts of aggression, Berkowitz and Lapage(1967) found out that in their experiment, frustrated men delivered more shocks to their partners when guns rather than badminton racquets happened to be in the room.
I have my notes here about cell division which could hep you solve the problem on your own.
The first period of the first phase (interphase) of the cell cycle is G1, followed by S and G2, and finally by the mitotic phase.
During G1, the ploidy (the quantity of DNA molecules in the cell) can be represented by the formula 2n (n is the number of DNA molecules in a gamete cell of a given species). During S, DNA duplicates and the quantity of genetic material increases from 2n to 4n. During G2, the quantity remains the same: 4n. After the mitotic phase, the quantity of genetic material decreases to 2n in each daughter cell.
