Light alerts the biological clock to slow down the secretion of melatonin hormone that promotes sleep. Melatonin hormone is a hormone that is produced by the pineal gland in animals and regulates sleep and wakefulness. . The hormone is used to regulate night and day cycles or sleep-wake cycles, darkness causes the body to produce more melatonin, which signals the body to prepare for sleep. Light decreases melatonin production and signals the body to prepare being awake.

Brilliant_brown [7]

Answer:

0 = -2, hence no solution.

Explanation:

4x + 2(x-5) = 3(2x-4)

4x + 2x - 10 = 6x - 12

6x - 6x = -12 + 10

0 = -2

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'
