The brain's suprachiasmatic nucleus regulates the body's circadian rhythms. The suprachiasmatic nucleus is a minute region of the brain located in the hypothalamus above the optic chiasm, the circadian rhythm is the 24-hour cycle of organisms, related to sunlight and temperature.
Biotic Factors are any living components that affect other organisms, and since soil is not alive (soil is an abiotic factor) then you can eliminate A., B., and C. D is the answer choice that has only biotic examples.
1. Ask a question: He thought how traits passed from one generation to another.
2. Form a hypothesis: His hypothesis was "Each plat has two factors for a trait, one from each parent.
3. Test hypothesis: He grew pea plants to see what will happen.
4. Make and record observations: He discovered that one factor alone doesn't determine the expression of the trait in the pea plant.
<span>5. Conclusion: Traits in pea plants are inherited from the parent pea plants.</span>
A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a <u>dimeric</u> protein.
- Isozyme is a multimeric forms of enzyme having similar specificity of the substrate but differences in kinetics and molecular weights of the enzymes.
- The banding patterns of isozyme observed from electrophoresis is related to the genetic conditions in which different combination of polypeptide chains exhibited under the mendelian principles.
- Hence with the intensity of 1:2:1 ratio, three banded phenotypes are formed having two homomeric and one heteromeric form from the dimeric protein in both multiple alleles at single loci and multiple /single allele at multiple loci.

You may be referring to the nucleus. The nucleus controls the cell, and it contains chromosomes (DNA) genetic makeup. Hope I could help|!
