Your airways are coated with a thin layer of liquid called ASL and a mucus gel layer, both which neutralize foreign particles to prevent infection. In people with
Cystic Fibrosis, a gene has an error, which causes the cells of the airways (lungs, etc) to have defective plasma membranes The ASL and mucus are much
thicker than usual near the defective cells, causing a lot of lung congestion because the defective cells allow too much salt into the cells Why would allowing too much salt into the cells create thicker ASL and mucus?
À. The increased salt in the cells makes the person thirsty, leading to thickened ASL and mucus in the lungs
B. The increased salt in the cells causes water from the airways to move into the cells by osmosis, thickening the ASL and mucus in the lungs.
C. The increased salt in the cells causes water from the cells to move into the airways, thickening the ASL and mucus in the lungs

Which part of an atom is responsible for absorbing energy and releasing it as colored light?
Answers
Answer:
The electron
Explanation:
The electron is responsible because it absorbs incoming energy by switching it's orbiting level one step higher and when releasing the given energy it jumps back to it's original orbiting level and emits visible light!
Answer: photons
Explanation: When an electron jumps from the second energy level to the first, it gives off energy by releasing light. The atom aborbes or emits the light in photons. Each photon has definite energy.

There are several ways to produce the amino acids that build a protein. What does this mean?
Answers
Answer: Some MRNA codons code for multiple amino acids. So they can produce amino acids many ways, that build a protein.
There are several ways to produce the amino acids that build a protein because the genetic code is DEGENERATE or REDUNDANT.
In a given messenger RNA (mRNA) sequence, the triplets of nucleotides or 'codons' indicate specific amino acids to be added during protein synthesis.
The genetic code is said to be 'degenerate' or 'redundant' because different codons may encode the same amino acid.
For example, both the AUC codon and AUA codon in mRNA specify isoleucine, so alterations (i.e., mutations) in the nucleotide sequence do not always alter the protein sequence.
In conclusion, there are several ways to produce the amino acids that build a protein because the genetic code is DEGENERATE or REDUNDANT.

How is cell differentiation different than mitosis?
Cell differentiation does not cause proliferation.
Cell differentiation produces cells with different gene expressions.
Cell differentiation only occurs after a wound.
Cell differentiation produces cells with different DNA.
Answers
Answer:
it should be produces cells with different gene expressions
The process of cell differentiation is different than mitosis by the mechanism that cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.
What is Mitosis?Mitosis may be defined as a type of cell division that produces two genetically identical daughter cells from a parental cell. It generally synthesizes diploid daughter cells. This process of mitosis occurs in the eukaryotic cells.
The generation of specialized cell types is called cell differentiation. It is the process during which a cell ceases to divide and develops specialized structural elements and distinct functional properties due to different gene expressions.
After the termination of cell differentiation, cells are structurally and functionally specialized with respect to their functions.
Therefore, the process of cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.

what is the relationship between kinetic energy and speed
Answers
Answer:
The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
The kinetic energy of an object is a function of its speed.
More specifically, the kinetic energy of an object is directly proportional to the square of the speed of the object.
Mathematically, the relationship between the 2 quantities can be represented such that:
Kinetic Energy = 1/2 x mass x velocity^2
Velocity refers to the speed in a particular direction.
Thus, for a 2 fold increase in speed, the kinetic energy of an object increases in 4 folds.

Capillaries pass oxygen and waste between blood and cells.
Red blood cells fight disease.
People with type O blood can receive AB blood donations.
The left ventricle controls the heartbeat.
Answers
Answer: Capillaries pass oxygen and waste between blood and cells.
Explanation: Capillaries are very thin-walled tubes that connect the arteries to the veins. The walls of these tubes are only one cell thick. Capillaries are found everywhere in the body. These thin tubes allow the food, oxygen, and waste to move between the bloodstream and cells. Waste products pass into capillaries and are carried by the veins to be disposed of in other parts of the body. Capillaries are the only blood vessels thin enough for materials to pass back and forth between cells and blood.
Blood Capillaries pass oxygen and waste between blood and cells. Thus option A is correct.
What are the function of blood capillaries?Capillaries are small type of blood vessels where a single red blood cell can barely fit in them.
They involve in the connection of arteries and veins, facilitate the exchange of certain elements between blood and tissues.
They involve in exchange of oxygen, nutrients, and waste between blood and tissues by two major process called passive diffusion and pinocytosis.
In passive diffusion the movement of a substance from the region of higher concentration to the region of lower concentration occur.
In Pinocytosis, intake of small molecules by the cell of the body like fats and proteins.
The capillaries wall are composed up of endothelium which is a thin cell layer called and surrounded by another thin layer called a basement membrane.
Thus option A is correct.
