Answer: the trichromatic theory of color vision
Explanation: The theory began when Thomas Young proposed that color vision results from the actions of three different receptors.
Answer: In direct effect, the person is directly affected by the source. For example, if a volcanic eruption occurs and lava flows outward, the area surrounding the volcano - including human establishments and organisms that reside there - would be affected (DIRECTLY); however, we observe that acid rain forms after this. This is because the sulfurous gases from the eruption mix with water vapor in the atmosphere. Another indirect effect of this is actually positive - radiation reflection. When a volcano eruptions, it releases gases like sulfur dioxide. Sulfur dioxide would react with other substances and produce aerosol particles. Aerosols can have huge impacts on our climate as they reflect light. This is evident when Mount Pinatubo erupted in 1991, and as a consequent, the aerosols that were produced from its gases cooled the area for 4 years.
Codominance is an inheritance pattern. Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.
<h3>What is codominance?</h3>
Codominance refers to the inheritance pattern in which a phenotype expresses two alternative variants coded by two alleles inherited from each homozygous parent.
When two individuals, that are homozygous and different for a trait, are crossed they produce heterozygous individuals.
These progenies express both parental phenotypes, as it is an additive expression of their parents' genes. Both alleles are equally expressed.
The is not complete dominance in these cases.
In the case of blood, the I gene determines the blood type of a person.
→ I is <u>completely dominant </u>over the i recessive allele.
→ Allele I can be either IA and IB, which are <u>codominant</u>.
- The person IAi expresses the A blood type ⇒ complete dominance
- The person IBi expresses the B blood type ⇒ complete dominance
- The person IAIB expresses the AB blood type ⇒ codominance ⇒ both alleles are simultaneously expressed
Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.

Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
