Energy flow can be defined
as the amount of energy that moves through a food chain and it flows through
ecosystem in one direction. Thus, the largest source of energy for an ecosystem
is the sun and the energy that enters the ecosystem is usually measured in
calories or joules.
The correct answer is A !
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'
Chloroplasts because that is the substance that gives leaves its green colour and also helps in photosynthesis
