In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of --
Answer:The option are not given, here are the options gotten from another website.
A. Aerobic respiration
B. Electron Transport Chain
C. Anaerobic respiration
D. Krebs cycle
The correct option is C.
Explanation:
This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.
In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.
In biology, an incomplete oxidation process is called fermentation, which does not require oxygen to take place, and which produces an organic substance as a result.
Fermentation consists of a process of glycolysis (breakdown of the glucose molecule) that produces pyruvate (pyruvic acid).
As it lacks oxygen as a receptor for the excess electrons of the NADH produced (nicotin adenine dinucleotide), it uses an organic substance that must be reduced to reoxidize the NADH to NAD +, finally obtaining a derivative of the initial substrate that is oxidized.
In this process, then, neither the mitochondria nor the structures linked to the cellular respiration process are involved.Only 2 molecules of ATP are produced per molecule of glucose consumed.It is carried out by the muscle cells that ferment glucose when the oxygen input is not enough to continue breathing.Therefore, we can conclude that many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.

6. Potential energy converts to Kinetic energy and Kinetic energy will convert to
Potential energy. Why does the total energy stay the same? *
The energy is not being created or destroyed: only transformed.
Total energy does not stay the same as some is always lost as heat.
Ο Ο
Energy stays the same because the energy has no where to go but in a system.
Answer:
The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. ... Once the potential energy locked in carbohydrates is converted into kinetic energy (energy in use or motion), the organism will get no more until energy is input again.

Answer:
Condensation is a process in which water vapors changed into liquid state.
Explanation:
Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.
A sudden, violent expansion of ________ would be considered an explosion.

describe how the skin works when the place is very hot
Answer:
when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.
Explanation:
Hope this helped Mark BRAINLEST!!!
Answer:
When it is hot, we normally sweat. Sweating removes the heat energy from our skin. Our blood vessels open up which lets more blood flow. This allows a way for the heat to be lost. It lets your body cool down or try and cool down.
Scientific knowledge is always changing. At one time, the kingdom was the
highest level of
classification. Today, the highest level of classification is the domain. Two of
the domains, Bacteria and Archaea both contain microscopic prokaryotic
organisms. What would be the best reason for scientists to separate the
prokaryotes?
A)There were too many species of prokaryotes to only have 1 domain for them.
B)It was determined that neither have chloroplasts.
C)Both organisms do not contain organelles.
D)Research showed differences in living environments.
Answer:
d
Explanation:whater
Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.
What are prokaryotes?The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.
Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.
A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

Answer:
A. high tide (A, C)
Explanation:
High tides on points A & C occur when the moon, the Earth, and the Sun are all lined up.
SUN -----<<< EARTH >>> ---
----MOON
( as accurate as it can be in 2D)
As you can see, they are all in a straight line. The gravity of both the moon and the Sun are combined to output the greatest amount of gravitational force as possible; creating high tides on the 2 sides of the Earth. Points A & C represent these two sides and are therefore the answer.
The white blood cells in the lungs release protease. Suggest the function of this enzyme in the white blood cells in the lungs.
( Pls don't answer for points. Serious answers only )
Answer: Protease is an enzyme which causes break down of proteins by converting them into smaller polypeptides or amino acids.
Explanation:
Proteases are the enzymes that are necessary for the functioning of the lungs. They cause the regeneration and repair of white blood cells as protease can digest connective tissue elements. They are responsible for generating an inflammation response during infection caused by a pathogen. Thus prevents lung infection. Inhibition of the anti-proteolytic mechanism is essential for the controlling microbial infection and lung inflammation.
d) Based on your above answers, do all substitutions cause a change in the amino acid sequence of a
protein? Explain
Answer:
No, they do not all cause a change in amino acid sequence of a protein.
Explanation:
Substitution mutation is the type of mutation that results when the nucleotide base of a gene is replaced by another base in the sequence. A substitution mutation can result into three different types of mutation namely; silent mutation, missense mutation, and nonsense mutation.
- In silent mutation, the nucleotide base that gets replaced by another still forms a codon that encodes the same amino acid as in the original sequence. e.g if guanine replaces adenine in the sequence, TTA to form a mutated sequence, TTG. This mutated codon (TTG) still encodes LEUCINE amino acid just as TTA does. Hence, there is no effect on the resulting amino acid sequence. This portrays that NOT ALL SUBSTITUTIONS cause a change in amino acid sequence of a protein.
