The right answer is A) lower the activation energy of chemical reactions.
The enzyme accelerates the reaction without changing the steady state.
Enzymes lower the activation energy of the substrate.
Activation energy or free activation energy is the energy that must be absorbed by the reagents to break their bonds.
The reagents must reach an unstable transition state in which the bonds are more fragile and easier to break.
Even an exergonic reaction requires the absorption of energy to reach the transition state.
Answer:
None of these.
Explanation:
(I) It is incorrect because mitosis is responsible for maintaining genetic integrity, and cell culture growth between daughter, and parent cell in a cell culture.
(II) It is incorrect because creation of gametes from the meiosis is a non-cyclical process, it happens one time, and ends in gametes creation such as ova, and sperm cell. On the other hand mitosis is a cyclic process.
(III) It is also incorrect because mitosis is a process which obtains cells with diploid no. of chromosomes, and in meiosis genetic transmission of DNA to offspring, the no. of chromosomes is reduced (diploid to haploid, not increasing).
Prokaryotes differ from eukaryotes in terms of cell complexity.
<h3>Differences between prokaryotes and eukaryotes</h3>
Prokaryotes refer to living organisms whose bodies are made from prokaryotic cells. Eukaryotes, on the other hand, are organisms made from eukaryotic cells.
Prokaryotes differ from eukaryotes in the following ways:
- Prokaryotes lack a nucleus while eukaryote organisms have one or more nuclei. The genetic materials of prokaryotes are arranged as nucleoids and lie freely within the cytoplasm.
- In terms of size, prokaryotic cells range from 0.1 to 5 micrometers. Eukaryotic cells range from 10 to 100 micrometers.
- Prokaryotic cells usually have cell walls. Some eukaryotic cells have cell walls, while some do not.
- The ribosome size of prokaryotes is around 20 nm while that of eukaryotes varies from 25 nm to 30 nm.
- In terms of evolutionary advancement, eukaryotes are more advanced than prokaryotes.

Swimming works the heart and lungs. This trains the body to use oxygen more efficiently, which is generally reflected in declines in the resting heart rate and breathing rate.
