What is the function of cholesterol in the cell membrane?
A. To allow substances too pass through
B. To prevent the hydrophobic tails from sticking together
C. To make more room inside the cell membrane
D. To help the cell recognize self and non self
Answers
The function of cholesterol in the cell membrane is C. To make more room inside the cell membrane.
What is the importance of the cholesterol?Cholesterol affects the bilayer structure of biological membranes in a variety of ways. It alters lipid bilayer fluidity, thickness, compressibility, water penetration, and intrinsic curvature.
Cholesterol molecules control the fluidity of the cell membrane, which allows the cell to maintain its shape. If cholesterol is missing from the cell membrane, excess fluidity may lead to cell lysis, or the breakdown of the cell.
As a result, cholesterol is required for cell membrane stability.
In conclusion, the correct option is C.

What kind of cell has one copy of each chromosome
Answers
Answer:
Germline cells
Explanation:
Germline cells, also known as se.x cells or zygotes, are the cells that are responsible for passing along the genetics of an individual to the offspring.
There is only one copy of each chromosome in these cells because they fertilize (combine) with another individual's germline cell to create the offspring. If there were more than one copy, the resulting offspring would not have diploid chromosomes.

Answers
Answer:
a. DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original
c. Each new DNA molecule contains an original strand and a newly synthesized strand.
Explanation:
DNA replication is an important process every cell must undergo prior to division. DNA replication is the process whereby DNA content is doubled. It occurs as a result of an enzyme called DNA polymerase, which synthesizes nucleotides.
DNA replication follows the semi-conservative model which uses one original DNA strand to synthesize a new DNA strand. The double-stranded DNA is separated into two single strands which serve as template for new strands. Due to the action of DNA polymerase, DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original.
Also, each newly synthesized DNA molecule which is similar to one another contains an original strand (template) and a newly synthesized strand.

Ketogenesis occurs primarily in the mitochondria of liver cells. Fatty acids are brought into the mitochondria via carnitine palmitoyltransferase (CPT-1) and then broken down into acetyl CoA via beta-oxidation.
skeletal muscle fibers can be classified into three major types based on two characteristics: the atpase activity of the protein , and the metabolic pathways used for the synthesis of
Answers
Skeletal muscle fibers are specialized cells that allow for locomotion and movement of the body and its parts. These cells are composed of proteins and are classified into three major types based on two characteristics – the ATPase activity of the protein, and the metabolic pathways used for the synthesis of ATP.
The first type of skeletal muscle fibers is the slow-twitch fibers, referred to as type I fibers. These fibers have low ATPase activity and rely on aerobic metabolism for ATP production. This makes them slow to contract, but they are able to generate sustained force over long periods of time. These fibers are found in muscles used for posture and balance.
The second type of skeletal muscle fibers is the fast-twitch fibers, referred to as type II fibers. These fibers have high ATPase activity and rely on anaerobic metabolism for ATP production. This makes them fast to contract, but they are only able to generate short bursts of power. These fibers are found in muscles used for quick bursts of strength, such as those used for sprinting and jumping.
The third type of skeletal muscle fibers is the intermediate-twitch fibers, referred to as type IIA fibers. These fibers have moderate ATPase activity and rely on a combination of aerobic and anaerobic metabolism for ATP production. This makes them a hybrid of the two extreme types, and they are able to generate both sustained force and short bursts of power. These fibers are found in muscles used for endurance activities, such as those used for running and cycling.

Describes three types of stimuli that cause plants to exhibit tropism.
Answers
Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.
The three stimuli that cause the plants to exhibit tropism are: Touch, light and gravity.
What is Tropism?
Tropisms are biological occurrences that signify the expansion or rotation of a living thing, typically a plant, in response to environmental stimuli. Tropisms are frequently connected to plants (although not necessarily restricted to them).
Movement or activity in response to a particular stimulus is more likely to be viewed by an organism where it is capable of purposeful physical movement (motility).
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light. 3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

the burning of coal to generate has been good in some ways and bad in others the electricity has allowed for an improvement in many areas of life but the burning of coal is also responsible for a great deal of pollution which activity helps solve the pollution problem through the use of new technology
Answers
The burning of coal to generate has been good in some ways and bad in others. The electricity has allowed for an improvement in many areas of life but the burning of coal is also responsible for a great deal of pollution.
Pollution problem is solved through the use of new technology such as carbon capture and storage, high-efficiency, low-emissions coal-fired power plants, and renewable energy sources such as solar, wind, and hydroelectric power.Carbon capture and storage is a process that captures carbon dioxide emissions from sources such as coal-fired power plants, transports them to a storage site, and stores them permanently underground.
Carbon capture and storage technology is an important tool in reducing greenhouse gas emissions and mitigating climate change.High-efficiency, low-emissions coal-fired power plants are designed to produce electricity with less coal and fewer emissions than traditional coal-fired power plants. These power plants use advanced technologies to improve the efficiency of the combustion process and reduce the amount of greenhouse gas emissions produced.
Renewable energy sources such as solar, wind, and hydroelectric power produce electricity without burning fossil fuels, so they do not produce greenhouse gas emissions or contribute to climate change. These sources of energy are becoming increasingly popular as the technology advances and the cost of producing electricity from renewable sources continues to decrease.

Answers
Answer:
A. They can aid in the transportation of molecules across membranes. TRUE
B. They are used in DNA replication. FALSE
C. They can act as cell surface receptors. TRUE
D. They are totally water soluble. FALSE
E. They can be enzymes. TRUE
Explanation:
A. They can aid in the transportation of molecules across membranes: This is the case, for example, of carrier proteins incrusted in membranes and in charge of transport. Active transport proteins are responsible for active transport. These transporters easily recognize a molecule and drive it into or out of the cell, an action that requires energy to occur. Also, channel protein and many carrier proteins are in charge of passive transport, which does not require energy.
C. They can act as cell surface receptors. Many proteins incrusted in cellular membranes act as receptors. A certain molecule binds to its receptor which is a protein structure that triggers an answer in the cell. As an example, we might mention neuronal communication through neurotransmitter (acetylcholine) that binds to its receptor in the postsynaptic membrane.
E. They can be enzymes. Enzymes are proteins, but not all proteins are enzymes. Some of the membrane proteins might be peripheral or integral enzymes, and their function is to catalyze reactions that must occur on the cell membrane.
