The genetic code is redundant. The meaning of this statement is that (D) More than one codon can specify the addition of the same amino acid.
Genetic code is a set of three nucleotides (mRNAs) that code for an amino acid together. The concept of given by Francis Crick. These codes are standard in majority of the organisms on Earth, hence the code is universal. For example, UGG codes for tryptophan.
Amino acids are the molecules that are involved in the formation of proteins. They have an amino group as well as a carboxylic group attached to the same alpha-carbon. There are 22 amino acids in the body that are involved in protein synthesis.

Constants are factors that are not changed in the experiment. Since the experiment is testing different colors of light on plant growth, light color is being changed, and is therefore not a constant. Hope this helps! :)
They are among the only types of organisms that get their energy from a non-living thing, and they give energy to Primary consumers, which give energy to secondary consumers, which give energy to tertiary consumers, which can give energy to decomposers, etc.
Abscission layer is the layer of cutinized parenchyma cells that develops in the abscission zone. The abscission zone form across the base of the plant part, where the break eventually occurs. During the photosyntesis chlorophyll using sunlight produces sugar and storches which are used as food by plant. And sugar accumulate in leaves.
