A catalyst accelerates a chemical reaction in a cell.
A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change itself.
Catalysts work by lowering the activation energy required for a reaction to occur. Activation energy is the energy barrier that must be overcome for a reaction to proceed.
By reducing the activation energy, a catalyst makes it easier for reactant molecules to come together and undergo chemical transformations, ultimately speeding up the reaction.
Catalysts are essential in biological systems as they enable various biochemical reactions to occur at the relatively mild conditions found inside cells, which would otherwise require higher temperatures or longer reaction times without catalysis.
In cells, enzymes are the most common type of catalysts. Enzymes are highly specific protein molecules that catalyze specific biochemical reactions, ensuring the efficient and precise functioning of cellular processes.

catalyst
Explanation:
Answer: True.
Explanation:
Organic fats are nonpolar molecules, while water is a polar molecule.
Since fats do not have any polar part in its structure, to be dissolved in water they would have to break some of water's hydrogen bonds. But this does not happen, so the fat is forced to stay separate from the water. This means nonpolar molecules are repelled by water and do not dissolve in it. They are hydrophobic compounds. So the lipids just float in the water without blending into it.
Answer:
waterway has its own particular characteristics related to water flow, velocity, and quantity.
Altered water ways or hydrology defines the variation in such characteristics including water flow. Water flow naturally depends on the climate and landscape ( valleys, mountains and flood plains).
There are several examples of people changing the way water flows such as construction of a dam or weir and the addition of a culvert or pipe. Dams are use to control the flow of water and through culvert or pipe, the flow or direction can be changed.
Changes in vegetation and landscape by people also affects the flow of water as well.
The three possible components of the DNA nucleotide is 2-deoxyribose, phosphate group, thymine. The correct option is C.
Deoxyribonucleic acid is a polymer made up of two polynucleotide chains which then tangle into one another to form a doublehelix.
It basically contains geneticinstructions for development, functioning, growth, and fertility of all lifeforms and viruses. Nucleic acids include DNA and ribonucleicacid.
The DNAnucleotide have following three components:
Thus, C is the correct option.

A. Use a microscope to observe cell division to determine the structure of operons.
B. Test the response of E. coli to a variety of chemicals to determine the number of operons that are present.
C. Insert the operons from one organism into another to determine the mechanism of operon expression.
D. Read the genome sequence to determine the quantity and organization of operons.
The experimental design that scientists use is to insert the operons from one organism into another to determine the mechanism of operon expression. Thus, the correct option is C.
E.Coli may be defined as a bacterial species that typically live in the intestines of both healthy people and animals. It is one of the organisms most frequently used in the technique of genetic modification.
Scientists used the experimental design which includes the role of E.Coli in inserting the operon from one organism to the other via the machinery of E.Coli and estimates the expression of the operon in that organism.
Therefore, it is well described above.
