In translation, the dehydration synthesis reaction is catalyzed by DNA polymerase enzyme. Therefore, the correct option is B.

What is DNA polymerase?

DNA polymerases are a group of enzymes that are responsible for catalyzing the synthesis of DNA. Their main function is to replicate the DNA. These enzymes work in pairs and a responsible for replicating two strands of DNA  in a tandem. DNA polymerases α and δ are primarily responsible for nuclear DNA replication. There are at least 15 DNA polymerases known to exist in humans.

Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids that will form a protein. This process involves the ribosome, which is responsible for assembling the protein chain by joining amino acids in a specific order dictated by the mRNA sequence. Therefore, the correct option is B.

the countries with the highest fertility rates are also the ones with the highest infant mortality rates. which one causes which and how do we know?

Answers

Answer: Higher infant mortality rates cause higher fertility rates.

Explanation:

Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.

Answers

The scenario that is best described here is a change in the region's BIODIVERSITY. This measure (biodiversity) indicates the genetic/phenotypic variability found in a region.

Biodiversity refers to the genetic and phenotypic variability of the organisms found in a particular geographic region or the variety of life on the Earth's planet.

Biodiversity can be used to indicate the amount of variation at different levels (i.e., genetic, species, and ecosystem levels).

how might differences in enzyme concentrations affect rates of photosynthesis and respiration?

Answers

Answer:

enzymes are biological catalysts which speed up the rate of biochemical reactions

Increasing the concentration of enzymes would speed up the rate of photosynthesis and respiration due to the fact that the enzyme substrate complex can occur on a much larger scale i.e. more enzymes would be able to bind with more substrates producing more Oxygen in the case of photosynthesis and more ATP in respiration

Decreasing the concentration of enzymes would have the opposite effects

The differences in enzyme concentrations affect rates of photosynthesis and respiration are process accelerators.

What enzymes are involved in photosynthesis?

Enzymes such as Rubisco, sedoheptulose-1,7-bisphosphatase, aldolase and transketolase dominate the control of photosynthesis. Reductive fixation of CO2 requires ATP and NADPH and their concentrations in the stroma increase when chloroplasts are illuminated.

The chemical reactions involved in photosynthesis are controlled by enzymes . The temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.

gene regulation can occur only during transcription and translation.

Answers

The statement described is false, gene regulation is a process that can occur at any time during the expression of a gene.

Gene regulation includes all those processes that affect the action of the final products of genes, that is, the regulation of the synthesis of macromolecules is called gene regulation or expression.

This regulation can be carried out at any stage of the synthesis or maturation of the macromolecules, and taking into account many variables it will be developed at the most appropriate point.

One of the most important regulation points is carried out at the level of transcription, since this is the initial stage of transfer of genetic information, control is achieved at the beginning.

Therefore, we can conclude that the pathway that leads from DNA to proteins is made up of multiple stages, and gene regulation can occur at any time during them.

There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.What is the main idea of this text?
