stealth61 [152]3 years ago
3 0

Helicase molecules is active first in DNA replication.  DNA helicase are enzymes capable of unwinding duplex DNA to provide the single- stranded DNA templates that are required in processes such as replication and recombination.all helicase separates the strands  double mix helix using energy derived from hydrolysis nucleotide.

Answer and Explanation:

Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.

The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.

In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).

The force required to prevent the movement of water across a selectively permeable membrane is __________ pressure
SOVA2 [1]

The force required to prevent the movement of water across a selectively permeable membrane is osmotic pressure. The plasma membrane forms a vesicle around the substances to be transported, and the vesicle around the vesicle is taken into cells.

Osmotic pressure depends on both the pressure gradient and concentration gradient.  This is only affected by the temperature and concentration of solute, each affect the movement of water across a membrane.

Higher the concentration is higher temperature increases osmotic pressure, which produced or associate with osmosis and dependent on molar concentration and absolute temperature. Hydro-static pressure forces fluid out of the capillary , osmotic pressure draws fluid back in.

It is called ecological succession, which can take up to a decade. It is a process of change in the species structure that occurs after a vast loss or extinction. Ecologists study how complexity is evident when a community is formed or occurrence takes place from an empty land or bare soil.

A psychology instructor is lecturing on the processes and mechanisms of messages in the nervous system. She has come to the part
trapecia [35]

Answer:

She should use the example of "the wave" in stadiums to illustrate the idea of a nerve impulse.

Explanation:

"The wave" in a sport stadium is a good example to explain how a nerve impulse works because it shows how an action potential travels from one point to its destination making changes in the membrane potential that would be the equivalent of people standing up and sitting down to allow the next row to do the same to reach its final destination.
