Answer:
Stabilize the DNA
Explanation:
DNA is defined as deoxyribonucleic acid comprises of phosphates group, deoxyribose sugar , amino acids base pairs namely adenine, cytosine , ,guanine and thymine.
Increase in temperature denatures the amino acids and proteins which means losing the basic structural unique properties .When it is denatured there is going to be a big difficulty in the use .
The results gotten from the DNA isolation if it isn't kept in an ice bath will be very inaccurate which is one of the main reasons why the DNA has to be put in it for the best result.
Answer:
A. Thermal Oxidizer.
Explanation:
It helps to destroy hazardous air pollutants and volatile organic compounds at a high temperature and releases them into the atmosphere.
If a biologist is measuring diversity by calculating the proportion of individuals of each species, he or she is actually calculating the species evenness of species in the community.
<h3>What is species evenness?</h3>
- When there is an environmental gradient in the study region, systematic sampling is performed.
- To take systematic samples along the environmental gradient, a transect is utilized.
- A population is a collection of creatures belonging to the same species that coexist in a certain location.
- Within a given area, more than one population may exist.
- It's possible for populations of Saguaro cacti, Cactus Wrens, and Bark Scorpions to coexist in the same places.
- A population is a collection of people belonging to the same species who are present in the same location at the same time.
- All of the people in all of the interacting populations in a given area make up a community.

Answer:
The correct answer will be option-B
Explanation:
Stromatolites are the sedimentary deposited mounds made of layers of phototrophic microbes which were usually present in the primordial times. The stromatolites are one of the oldest fossils is known today which were formed in the shallow water.
They are composed of the phototrophic bacteria or cyanobacteria which survived and still survive by using the carbon dioxide and sunlight to make food material.
Since the bacteria are the prokaryotic organism therefore, the Option-B is the correct answer.
