8. People use NADH supplements as medicine. NADH is used for improving mental clarity, alertness, concentration, and memory; as well as for treating Alzheimer's disease and dementia. Because of its role in energy production, NADH is also used for improving athletic performance and treating chronic fatigue syndrome
9. Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.
10. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen.
11. fermentation, carbon dioxide, is used in bread making and the production of carbonated beverages.
12. i dont know
13. The CO2 produced by the Krebs cycle is the same CO2 that you exhale. The electron carriers NADH and FADH are sent to the final step of cell respiration, which is respiratory electron transport. The Krebs cycle does not use oxygen, though it does stop in the absence of oxygen because it runs out of NAD and FAD.
14. Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
15. The Krebs cycle occurs in the mitochondrial matrix and generates a pool of chemical energy from the oxidation of pyruvate, the end product of glycolysis.
16. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria.
17. In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

How do oceans contribute to creating winds?
A.Ocean currents create momentum that pull air with them.
B.Ocean water vapor pushes air causing it to flow in different directions.
C.Ocean energy is transferred to or from the air creating density differences.
D.Ocean water vapor eventually condenses into clouds and wind.
Answer:
Explanation:
Ocean energy is transferred to or from the air creating density differences.
Oceans contribute to creating winds as ocean energy is transferred to or from the air, creating density differences. The correct option is c.
What is ocean energy?The ocean waters are continually changing. Wind, water salinity, temperature, ocean floor topography, and the earth's rotation all influence ocean current flow patterns.
The majority of ocean currents are caused by wind and solar heating of surface waters near the equator, while some are caused by density and salinity fluctuations in the water column. In contrast to tidal currents along the shore, ocean currents are typically consistent and travel in one direction.
The transfer of energy from the ocean to the atmosphere causes the atmosphere to cool. The energy travels in a disturbance, which in an ocean is a wave, therefore the wave generates energy and transports it through the water.
Therefore, the correct option is C. Ocean energy is transferred to or from the air, creating density differences.

Answer:
Schistosomiasis is a disease caused by infection with blood flukes of the geneticist Schistosomiasis. Transmission of, and exposure to, the parasite result from fecal or urinary contamination of freshwater containing intermediate host, snails, and dermal contact with the same water.
Explanation:
Snails can carry diseases such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis, and schistosomiasis. Be cautious when stepping into freshwater, because there may be snails in it. I recommend not picking up or touching snails.

Both starch and cellulose are polysaccharides made of individual glucose molecules. Why then can humans digest starch but not cellulose
Answer:
Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. ... Your body contains enzymes that break starch down into glucose to fuel your body. But we humans don't have enzymes that can break down cellulose

As thermal energy is added to a substance, which of the following changes can be predicted?
O
Spacing between particles will decrease
Vibration of individual particles will increase
Temperature of the substance will decrease
The pressure of the air around the substance will increase
Answer:
Vibration of individual particle will increase
Explanation:
This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.
the number of two digit is equal to four times the sum of digits. if the product of digits is 8 .find the number.
Answer:
I think you are only intended to find
24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24
That works as well

This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Which of the following statements BEST describes ASEXUAL reproduction?
Question 8 options:
A single-celled organism uses meiosis to create two identical copies of itself.
Two multi-celled organisms uses meiosis and fertilization to create a unique offspring.
Two multi-celled organisms use mitosis and fertilization to create a unique offspring.
A single-celled organism uses mitosis to create two identical copies of itself.
The statement “ A single-celled organism uses mitosis to create two identical copies of itself” best describes asexual reproduction
The statement which best describes the mode of asexual reproduction is that a single-celled organism uses mitosis to create two identical copies of itself. Thus, the correct option for this question is D.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction in which a new offspring is produced by a single parent. This type of reproduction does not involve the fusion of gametes or a change in the number of chromosomes.
Asexual reproduction is homologous to the process of mitosis. This is because both of them involve the production of two identical daughter cells from a parental cell.
While meiosis produces four daughter cells which are genetically unique to the parent cells. It is the characteristic feature of sexual reproduction that is opposite to an asexual one.
Therefore, the correct option for this question is D.
