B)Bacteria
Cause viruses are not prokaryotes
<u>Given:</u>
No. of protons = 8
No. of Neutrons = 9
No. of electrons = 8
<u>To find:</u>
Atomic mass =?
<u>Formula to be used:</u>
Atomic mass = No. of protons + No. of Neutrons
<u>Answer:</u>
Atomic mass = No. of protons + No. of Neutrons
Atomic mass = 8 + 9
Atomic mass = 11
<u>Explanation:</u>
Atom is composed of three subatomic particles namely proton, electron, and neutron. The composition of these sub atomic particles is used to calculate the atomic mass.
The atomic mass of the element is nothing but the sum up value of the total <em>number of protons and neutrons</em> present in the nucleus of the atom of the element.
According to the given data, the atomic mass of the element with 8 protons and 9 neutrons is found as <em>11</em>.
The statement that is true regarding criteria and constraints is that criteria are more important than constraints (option A).
<h3>What are criteria and constraints in engineering?</h3>
Criteria in engineering are things a design needs to do in order to be successful, like its requirements.
On the other hand, constraints are limitations on the design e.g. materials available, the cost of the materials, the amount of time they have to develop the solution, etc.
Since the design criteria are the explicit goals that a project must achieve in order to be successful, they are far more important than the constraints.
Therefore, the statement that is true regarding criteria and constraints is that criteria are more important than constraints.

Answer & explanation:
Amylase is part of enzymes, a group of large peptide molecules (formed by amino acids) whose role is to catalyze reactions in order to facilitate the synthesis of other biological molecules.
Amylase is found mainly in saliva (in the form of salivary amylase, or ptialin), acting in the breakdown of starch and glycogen in foods, reducing them to smaller particles, facilitating their digestion and absorption.
The action of enzymes depends on certain specific conditions, called optimal conditions. In the case of <u>amylase</u>, it depends on an optimum pH of 7 (neutral) and an optimum temperature of approximately 37 ° C.
This enzyme can still act between 35 ° C and 40 ° C, but below 35 ° C it is inactivated, preventing its functions from being performed, and above 40 ° C it suffers denaturation, causing changes in its structures.
Thus, it is concluded that the <u>temperature</u> (under optimal conditions) is important for enzymes because it keeps their actions and structures in proper operation.
