Answer:

It is unchanged and can be used again for the same chemical reaction.

Explanation:

Enzymes are bio-catalysts which speed up the rate of chemical reactions by <u>lowering the activation energy</u> for the reaction and <u>producing binding energy</u>. But during chemical reaction the enzymes are unchanged and can be reused for the same chemical reaction. Most of the enzymes are proteins and without enzymes a biochemical reaction cannot take place.

For example: Amylase catalyzes the conversion of starch into sugar.

A scientist constructs a graph to show the age structure that f the human population of county
DedPeter [7]

Based on the graph, it can be concluded that the population is increasing rapidly because of the youth of the population.

<h3>What is population?</h3>

The population of a species is the number of organisms of the same species found within a given habitat.

Population graphs are used to describe the trend in the population of a given species of organisms.

The factors that affects population growth of a country include:

  • fertility rates,
  • mortality rates or life expectancy,
  • the initial age profile of the population, and
  • migration

Given the population graph of the country, the conclusion can be drawn is that the population is increasing rapidly because of the youth of the population.

In conclusion, the higher the fertility rate the faster the population growth.

How is gene regulation in prokaryotes and eukaryotes similar how is it different?
Triss [41]
Prokaryotes are unicellular (single-celled) organisms and on the other hand Eukaryotes are multicellular organisms and more developed in organ and structure compared to prokaryotes. Gene regulation is key to both organisms as it determines growth and development and other process and activities performed by the organism. However, the two organisms differ in the way they regulate their genes. Prokaryotes cells lack nucleus while the eukaryotic cells have a well defined nucleus. In Prokaryotes RNA transcription and protein formation occur almost simultaneously while in the Eukaryotes RNA transcription occur before the protein formation in the nucleus and then protein formation occurs in the cytoplasm. In addition both organisms uses the same processes in gene regulation  and only differ in the manner the processes are undertaken. Lastly, gene expression in prokaryotes is regulated at transcriptional level whereas in eukaryotes regulation is at many levels.
