Calculate the percentage of viable cells
102/112x100
Answer:
91.07%
Explanation:
Given the expression
102/112 x 100
This can also be expressed as;
= (2*51)/(2*56) * 100
= 51/56 * 100
= 5100/56
= 91.07%
Hence the percentage of viable cells is 91.07%

B. Lysosomes are needed to store energy
C. Lysosomes are needed to package proteins
D. Lysosomes are needed to synthesize proteins
Answer:
A
Explanation:
Lysosomes break down cell parts when needed, and can self-destruct the cell. Organelles are made of biomolecules, the building blocks of life. Therefore, A is the answer. Hope it helps :)
When an inducer is added to a medium containing an organism with a metabolic pathway controlled by a repressor, the inducer then Group of answer choices combines with the substrate and blocks induction. does not combine with, but rather functions as a chaperone molecule for, the enzyme-substrate complex. combines with the repressor and activates the repressor. combines with the substrate and activates induction. combines with the repressor and inactivates the repressor.
Answer:
The correct answer is - combines with the repressor and inactivates the repressor.
Explanation:
The role of inducers is to bind with a repressor in a metabolic pathway and cause them to change their shape. This modification of the shape in the repressor structure prevents them to bind with the DNA and the metabolic pathway continues.
So, inducers inactivate the repressors by binding them. For example in Lac operon lactose, an inducer bindswith the repressor and dissociates it from DNA and inactivates the repressor.

Makali and his parents recently emigrated from the highlands of Papua New Guinea. His family is part of the famous Fore tribe; after living in the tribe for most of their lives, they decided to give Makali a different life in the United States. His mother starts to cry as she recalls that both her parents died in the kuru epidemic that made the tribe famous, and she is terrified that Makali might be coming down with kuru. His father interjects to say that it is not possible and that he is far more concerned that Makali has some other infectious disease to which he had never previously been exposed.
His father says that Makali had a severe allergic reaction to the tetanus/pertussis booster shot as a child and has been unable to be re-vaccinated due to the risk of anaphylactic shock. Therefore, Makali may be susceptible to whooping cough (pertussis). This would not have been a concern 10 years ago, but vaccination rates for whooping cough have plummeted in the United States, eliminating herd immunity and sparking a return of the disease in some regions. Ironically, vaccination rates in the Fore tribe are much higher than in the United States, so Makali's parents had concerns about coming to the United States, which is falling behind other countries in this area of basic medical care!
One of the doctors you are working with says that checking immunoglobulin (Ig) levels should reveal if there is a serious infection. He also points out that kuru does not cause immunoglobin levels to rise. If Makali does have kuru, a brain biopsy may be required to make a definitive diagnosis.
1. Select the next step or steps that would be appropriate to diagnose Makali?
a. Test immunoglobulin (IgG, IgA, and IgM) levels in the blood for signs of infection.
b. Perform a brain biopsy.
c. Interview one of Makali's friends to ask about the day he first became sick.
2. Which statement most accurately describes the citric acid cycle?
a. It is an unregulated process, like an intersection without signal lights.
b. It is the main center of ATP production during anaerobic metabolism.
c. It plays a central role in key metabolic processes in the cell, with many metabolic intermediates leaving and entering.
d. It serves a catabolic role only, which is to generate ATP and reducing equivalents for cellular energy needs.
Answer:
Explanation:
It is important we understand what is immunoglobulin test.
Immunoglobulins, also known as antibodies, are measured by the test carried out in the blood. Antibodies are proteins produced by the immune system to combat pathogens such as viruses and bacteria that cause disease. Immunoglobulins are proteins produced by the body to combat various substances.
The immunoglobulin assay tests three forms of immunoglobulins in total. IgG, IgM, and IgA are the three types of antibodies. IgG, IgM, and IgA levels that are too low or too high may indicate a severe health condition.
Thus, from the above question; the next step that would be appropriate is:
Assuming the test uncovers an increase in immunoglobulin, it demonstrates contamination or infection. Thus, a fitting treatment ought to be begun against the infection.
However, suppose the text doesn't uncover an increase in immunoglobulin and assuming he shows manifestations of symptoms, then the brain biopsy ought to be performed to affirm the diagnosis of kuru.
(2)
The citric acid cycle is the metabolic center of the cell. It is the doorway to the aerobic metabolism of any molecule that can be changed into an acetyl group or a part of the citric acid cycle. The cycle is additionally a significant wellspring of prototype for building blocks of numerous different molecules like amino acid and nucleotide base.
Thus, the best accurate statement is: Option C

Describe DNA synthesis in detail
Answer:
DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.
Answer:
The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.
Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.
(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.
(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.
(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

What similarities are there in growth of the human population compared to animal/plant populations?
The similarities between the growth of the human population and that of plants and animals can be seen in the fact that in all three instances.
Briefing:With respect to the original number of specimens, the increase happens exponentially.
If there are 100 humans and 50 of each gender, then it is possible for 50 additional people to appear;
Animals and plants both reproduce exponentially compared to the procreative couples that were previously there.
Why is plant population important?Due to the encouragement of apical dominance and the subsequent induction of barrenness, a high plant population ultimately results in a reduction in the number of ears produced per plant of maize. Plant populations should constantly remain at their ideal levels.

10. At 100x, you will see a cell that is larger and has a dark shape in it. This cell doesn't look like the others because it is a
white blood cell and it functions to protect your body against microbes. Red blood cells do not have a nucleus. White blood cell
count is used as a diagnostic tool to determine if someone is sick. If you were fighting an infection, would you expect to have
more or less WBC's? Why?
Answer:
More
Explanation:
When your body needs more of a cell, it produces more of that cell. Since WBC’s (white blood cells) are used to fight infections, if you are sick you need more of them. Hope it helps :)
