Answer: afforestation
Explanation:by planting trees they would be able to "inhale "the carbon iv oxide and in exchange exhale Oxygen
Answer:
Primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
Explanation:
DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.
Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.
Regarding the question above, the primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
Answer:
Cellular Respiration: a process able to extract a large amount of energy from food molecules. In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.
