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.
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
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.

There are several ways to produce the amino acids that build a protein. What does this mean?
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.

Which of the following statements is true?
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.
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.

please follow meDescribe the relationship between particle motion, temperature, and thermal energy.
Answer:
The average energy of motion of particles in a substance is its kinetic energy. Therefore, temperature is the measure of the average kinetic energy of the particles of a substance. The thermal energy of the substance is the total energy of the substance.
Explanation:
We want to explain the relationship between particle motion, temperature, and thermal energy.
First, let's explain the relationship between thermal energy and temperature.
When we have a given object, as we give it thermal energy (there are different ways, like radiation, conduction, etc) the temperature of the object increases.
So we can say that the temperature is a measure of the stored thermal energy.
Now, the relation between temperature and particle motion is more interesting.
As we increase the temperature of a given object, the increase in energy (again, the temperature is related to energy) comes from an increase in the kinetic energy of the particles that make the object.
Thus, when we increase the temperature of something, the particles that conform it move more (remember that the kinetic energy is related to the velocity of the particles). This is why we usually see an increase in the volume when we heat up something.
And also this is why most elements have more volume in the gas phase than in the liquid phase, for example.
These are the relations between thermal energy, temperature and particle motion.
