Pepsin becomes completely inactive at a pH of about 3.5 because the protein chain in the enzyme is denatured.
The correct answer is B) The protein chain in the enzyme is denatured, permanently inactivating it as the pH approaches 7.
Enzymes are specialized proteins that facilitate chemical reactions in the body. Pepsin, being an enzyme, has an optimal pH range for activity, which is between 0.5 and 2.5 in this case. Pepsin works by breaking down proteins into smaller peptides. However, when the pH increases and approaches 7, the protein chain in pepsin becomes denatured, resulting in a permanent loss of its catalytic function.

b. will be considered in the decision making process
c. will not be considered in the decision making process
d. None of the above
Answer: The correct answer for the blank is -
b. will be considered in the decision making process.
Explanation:
As per the given information in the question, satisfaction of customer is a criterion for decision making. This indicates that it will be considered in the process of decision making. However, there would be some other criteria that would also infleunce the process of decision making.
Thus, option b) is the right answer.
lighter and stronger than previous models that they can sell at a higher price.
Which statement describes how a risk would be factored into a cost-benefit
analysis?
A. The cost of the materials to make the frames would be added to
potential improvements in consumer safety.
B. A reduction in employee safety would be added to the increase in
sales of the bicycle frames.
C. The ecological damage of mining the materials would be
subtracted from the profits made by selling the bicycle frames.
D. The money spent manufacturing the frames would be subtracted
from the profits made by selling the bicycle frames.
Cost-benefit analysis has been defined as the approach used to evaluate the advantages and disadvantages of the choices. The ecological damages must be subtracted from selling profits. Thus, option C is correct.
Cost-benefit analysis has been defined as the estimation of the cost and the profits in economical terms. It allows the determination of the monetary benefit gained by the manufacturing, production, and selling of the products.
To manufacture the bicycle frame the monetary benefit can be estimated by subtracting ecological damages for material mining from the profits earned by selling the frame of the bicycle. It gives the idea of how much it cost and benefits the maker.
Therefore, option C. (profits - ecological damage) gives a cost-benefit analysis.

The statement that mitochondria and chloroplasts cannot survive outside of the cell is not a supporter of the endosymbiotic theory. So the correct option is A.
It's possible that eukaryotic cells originated when several cell types fused to form one. They started coexisting in what are known as symbioticpartnerships. The endosymbiotic theory describes how this may have occurred. One creature that resides inside of another is known as an endosymbiont. Your own cell and all other eukaryotic cells are animals formed of other species' components.
Both the chloroplast and the mitochondrion are organelles that were formerly free-living cells. They were prokaryotes that were ensconced within other cells (host cells). They may have become a part of the other cell by being eaten (a process known as phagocytosis), or they could have been parasites living inside the host cell.
The inner cell lived and flourished with the host cell rather than being ingested by or destroying it. It resembles a landlord and a renter in certain ways. The organelle pays rent by producing energy that the host cell may consume, and the host cell offers a cozy and secure home.
The organelle and the hostcell have developed together throughout time as a result of this long-ago event. The two are now inextricably linked. Even while they now work as a single organism, if we look closely, we can still see traces of the organelles' former lives as free-living entities.
Therefore the correct option is A.
