Biology
1 answer:
sashaice [31]3 years ago
4 0

Answer:

B. Enzymes decrease the activation energy of the reaction :)

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Which of the following descriptions about RNA is not correct?
gayaneshka [121]

Answer:

The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".

Explanation:

Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.

What are particulates? Why are they important?<br>​
Valentin [98]

Answer:

Particulates are small particles, roughly one to a few tens of micrometers in size, suspended in the air. They are individually invisible but in large concentrations, they may give a "color" to the atmosphere. The extent to which particulates are present in the atmosphere are an important indicator of air quality.

Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction.
baherus [9]

Answer:

Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>

Explanation:

Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
