They are used to directly amplify segments of dna
C clouds
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.
Answer:A
Explanation:
A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar, and a phosphate group. The nitrogenous base is either a purine or a pyrimidine. The five-carbon sugar is either a ribose (in RNA) or a deoxyribose (in DNA) molecule.
Answer:

Explanation:
A limiting factor is anything that constrains a population size and slows or stops it from growing,so when predators move into the ecosystem they compete with other organisms for resources
