Your lab manual says that the nutrient agar control plate in this experiment, is "a comparison for growth quality." Explain why the results on the nutrient agar plate are necessary to justify your conclusions about the mannitol salt agar plate\.\*
Answer:
Nutrient agar lets us know about the presence/absence of any kind of bacteria.
Mannitol salt agar let us know about the presence/absence of osmotolerant bacteria.
The difference between them lets us know which bacteria are osmotolerant and which ones are not.
Explanation:
The mannitol salt agar is useful to identify organisms with specific traits. It is a selective medium that only allows the growth of osmotolerant cells. It is used to identify bacteria such as Staphylococcus aureus.
The comparison between nutrient agar and mannitol salt agar is significant because it gives more information about the bacteria type. If no cell grows in these two mediums means that there are no bacteria at all. But if cells can grow in the nutrient agar and not in the mannitol salt agar, it means the growing bacteria are not tolerant to salty mediums. They are not osmotolerant.
A comparison between the presence/absence of bacteria growing in each medium lets us know which species are osmotolerant and which ones are not.

Compression of mortality is the extent to which an organ can preserve essentially normal function despite decreasing cell number or cell activity. Group of answer choices True False
Answer: False
Explanation:
Compression of mortality refers to the reduction over time with regards to the variance of the age of people at death.
The extent to which the organ can help in preserving normal function despite the fact that there's a reduction in the number or cell activity is referred to as compression of morbidity.
When morbidity is compressed, it should be noted that individuals can be expected to live healthier and longer as well.
Therefore, the statement is false

Answer:
B. decreasing the carbon dioxide level in the atmosphere
Explanation:
1. Metabolic pathways Metabolism of ketone bodies involves several different pathways, such as the production of glucose (gluconeogenesis), the oxidation of fatty acid, and the citric acid cycle. All of these pathways are part of energy metabolism, which is composed of reactions involved in generating or storing metabolic energy. There are two major divisions in metabolism:
1. processes in which complex substances are degraded to simpler molecules accompanied by the net release of chemical energy and
2. processes concerned primarily with the synthesis of complex organic molecules, which requires a net input of chemical energy.
Some pathways, such as the citric acid cycle, can serve in both functions. Oxaloacetate is an important intermediate in several of these pathways, especially the citric acid cycle. Depleted oxaloacetate, just like other citric acid cycle intermediates, has to be replenished to maintain flux through the cycle. Separate metabolic pathways serve this purpose by balancing the flow of carbon in and out of the cycle. Define the major metabolic pathways by completing the sentences. Match the words in the left column to the appropriate blanks in the sentences on the right.
a. catabolic
b. anabolic
c. anaplerotic
d. amphibolic
1. A(n)____process is the process in which complex biomolecules are built up from simpler.
2. The____pathway involves both catabolic and anabolic processes.
3. A(n)____process is the process that replenishes the stores of citric acid cycle intermediates.
4. A(n)____process is the process by which complex molecules are broken down to simpler ones.
2. Identify the reactants and products of the citrate synthase reaction in Step 1 of the citric acid cycle. Drag the appropriate participants to their respective bins.
a. acetyl-CoA
b. citrate
c. heat
d. CoA-SH
e. oxaloacetate
1. Reactants
2. Products
3. Neither
3. Mechanism for elevated ketone formation
After analyzing the role of oxaloacetate in the first step of the citric acid cycle and formation reactions of ketone bodies above, your research group proposed several possible mechanisms for increased ketone bodies levels when oxaloacetate is depleted. Based on the information about ketone body synthesis, predict which possibility is the most reasonable.
A. Another molecule (unknown at this point) reacts with available acetyl-CoA to form acetone, one of the ketone bodies.
B. Lack of oxaloacetate frees the enzyme, citrate synthase, to be diverted to catalyze the formation of the ketone bodies.
C. Oxaloacetate is unavailable to react with acetyl-CoA, resulting in acetyl-CoA being converted into acetoacetate, one of the ketone bodies.
D. Oxaloacetate is an inhibitor of the enzyme catalyzing ketone body formation, thiolase; a lack of oxaloacetate activates the enzyme and increases the production of the ketone bodies.
4. Replenish oxalate in animals
What enzyme catalyzes the reversible, biotin-dependent carboxylation of pyruvate to give oxaloacetate in animals?
a. pyruvate carboxylase.
b. phosphoenolpyruvate carboxylase.
c. malate dehydrogenase.
d. phosphoenolpyruvate carboxykinase.
Answer:
1. anabolic, amphibolic, anaplerotic and catabolic.
2. acetyl-CoA and oxaloacetate---- reactants
citrate, CoA-SH and heat -------products
4a. pyruvate carboxylase.
Explanation:
An anabolic process is a type of process in which complex biomolecules are formed from simpler molecules. The amphibolic pathway is a biochemical pathway that consists of both catabolic and anabolic processes. An anaplerotic process is a type of process that replenishes the stores of citric acid cycle intermediates. A catabolic process is the process by which complex molecules are broken down to simpler ones.
acetyl-CoA and oxaloacetate are the reactants whereas citrate, CoA-SH and heat are the products of citrate synthase reaction of the citric acid cycle.
Pyruvate carboxylase is an enzyme catalyzes and conversion of pyruvate to oxaloacetate.

Answer:
Helping others is the characteristics of human beings.
Explanation:
It is very important to stand up for others because helping others is the property of human beings. Those people who stand for other people and help them in their difficult situation, these people helped by the God and these people get happiness and prosperity in their life while on the other hand, those people who can't stand for other people will also can't receive help from others in difficult and needy situation. This stand also shows your courage and bravery to the opposite party.

Explanation:
describe how the force of gravity from Earth could affect nearby Apollo asteroids and explain how the effect of Earth’s gravity could change the orbital motion of an Apollo asteroid.
Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.
The force of gravity from the Earth could affect nearby the Apollo asteroids and this gravitational force is responsible for pulling the objects towards itself which could change the orbital motion of an Apollo asteroid.
What is the Apollo asteroid?Apollo asteroids are also called as the near-earth asteroids. These are a major source of the meteorites which occasionally fall to the earth. Asteroids with the orbits that approach the earth, are passing inside the perihelion of the Mars, and these are called as Amors. Those that cross the orbit of the earth are called as the Apollo asteroids.
Gravitational force is the force which pulls all the objects in the universe towards each other on the planet and in its orbit. On the Earth, gravity pulls all the objects downward towards the center of the planet.

Hydroelectric power is much cleaner and safer source of energy compared to coal, instead of digging out the Earth, we simply use its natural flowing water. Using hydroelectric power also ensures we do not suffer from the smog and harmful chemicals emitted by coal powered plants. A cleaner environment ensures happier people, a healthier ecosystem, and overall a better place to live. Not all areas can harness local water systems like our Town, we are lucky to even have the opportunity to live on hydroelectric power. Due to this, we can simply use the coal we mine and sell it to other less fortunate towns, while not needing to worry about our electricity or coal economy.

Answer:
A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa (singular, septum). Septa usually have little pores that are large enough to allow ribosomes, mitochondria and sometimes nuclei to flow among cells.
