C. Positive Feedback
This is because a response to a stimulus( low blood pressure) acts in the same direction as the stimulus ( even lower blood pressure).
This is opposed to negative feedback where the response would go in the operate direction of the stimulus ( I.e. blood pressure increasing in response to low blood pressure)
Answer:
c. Scoliosis
Explanation:
Scoliosis is a defect which is as a result of the spine being imbalanced and developing into an S- or C-shaped curve.
The spine is usually curved in an uncharacteristic manner and is commonly found in people with cerebral palsy.
Treatment involves surgical operations or the use of braces to fix the spines back to their original positions.
Answer:
The stretch of DNA transcribedinto an RNA molecule is called atranscription unit and encodes at least one gene. If the gene encodes a protein, thetranscription producesmessenger RNA (mRNA); the mRNA, in turn, serves as a template for the protein's synthesis through translation.

A new nucleotide can only be added to the 3' end of a growing dna strand. dna therefore always grows in the 5' to 3' direction.
Define nucleotide.
Nucleotides are organic molecules made up of a phosphate and a nucleoside. They serve as monomeric units of the essential biomolecules found in all life forms on Earth, deoxyribonucleic acid(DNA) and ribonucleic acid polymers.
Define DNA.
Deoxyribonucleic acid(DNA) is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce. Nucleic acids include DNA and ribonucleic acid.
