Two main factors that must be taken in consideration are temperature and the pH level.
The temperature shouldn’t be too low as it slows down the rate of reaction, meaning that the enzyme will work slower, but also not too high as it will cause the enzyme to denature (stops working as it should).
The pH level is pretty much the same, shouldn’t be not too low nor too high.
Most appropriate answer is D !As vessels dialates the velocity of the blood flow decreases !
So both C and D is appropriate! But I will suggest D !

Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question can be seen in the document attached.
There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).
A. Found in all matter
Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).
B. Negative charge
Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>
C. Exists in the nucleus
The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.
D. Attract opposite charges
They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.
E. Moves at extreme speed
Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.
F. Bound by strong force
The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.
