Answer:

C. the effects of an earthquake on blood pressure

Explanation:

Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.

Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.

Nikolay [14]

Explanation:

The cells store glycogen and neutralize toxins and are present in coelomic fluid of some annelids. They are yellowish in colour due to the presence of yellow granules called chloragosomes.

These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.

Howard is explaining the process by which DNA determines the structure of proteins. His explanation includes this statement. "Th
andrew-mc [135]

Answer:

Transcription and RNA processing (splicing)

Explanation:

Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.

This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.

Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.
