Can enzymes be reused
Masja [62]

If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.

iris [78.8K]

The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.

<h3>What is Reaction time?</h3>

This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.

Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.

Andru [333]

Answer:

The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).

Explanation:

The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.

Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.

Which are typical pioneer species during primary succession?
JulijaS [17]

Answer & explanation:

Primary succession occurs in environments that did not have biological communities in place and present unfavorable conditions for the establishment of life. Examples of these sites are rocks, dunes and newly solidified lava pits.

The pioneer organisms in primary succession are mainly producers and some decomposers.

In <u>dune</u> <u>environments</u>, for example, there are grasses, whose seeds are wind-borne and able to withstand excessive heat, water scarcity and unstable soil, and their roots are firm, preventing these plants from being harmed by the wind.

Sites with <u>rocky</u> <u>surfaces</u> can be colonized by photosynthetic bacteria, fungi or some species of algae. These organisms release substances that alter the substrate, allowing the installation of new species over time.
