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.

How are chemosynthetic bacteria different from photosynthetic bacteria?
A Chemosynthetic bacteria do not require water B Chemosynthetic bacteria eat tube wormS. C. Chemosynthetic bacteria require intense sunlight
D. Chemosynthetic bacteria do not need light.
Answer:
D
Explanation:
Chemosynthetic bacteria different from photosynthetic bacteria in that Chemosynthetic bacteria do not need light and the correct option is option D.
Chemosynthetic bacteria are a type of bacteria that can produce their own energy and organic compounds without the use of sunlight. They obtain their energy by oxidizing inorganic substances, such as hydrogen sulfide or methane, and using the energy released from these chemical reactions to synthesize organic molecules.
In contrast, photosynthetic bacteria, including cyanobacteria, use sunlight as a source of energy for photosynthesis. They have pigments, such as chlorophyll, that capture light energy and convert it into chemical energy through a series of biochemical reactions.
Chemosynthetic bacteria can thrive in environments with little or no light, such as deep-sea hydrothermal vents or certain underground ecosystems. They are able to utilize chemical energy sources to sustain their metabolic processes and support their growth and reproduction.
Thus, the ideal selection is option D.

Which part of an atom is responsible for absorbing energy and releasing it as colored light?
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.

4. How are atoms related to molecules?
Answer:
Every combination of atoms are molecules. A compound is a molecule made of atoms from different elements.
Explanation:
Atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.
What is the significance of the atoms and molecules?They are both significant because they are both the basic building blocks of matter, and atoms in a molecule are held together by various types of bonds, such as ionic bonds and covalent bonds, etc. Water molecules, for example, are made up of oxygen and hydrogen, which are the atoms that combine to form the molecule.
Hence, atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.

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.

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.

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.
