Answer:
Alleles
Explanation:
In diploid organism, genes occur in pairs on chromosomes and such pairs are referred to as allelic pairs. An allele is an alternative form of the same gene that controls the development of a pair of contrasting genes. The genetic constitution of an organism is known as genotype while its phenotype refers to a set of observable characteristics of an organism which are an expression of an individual genotype.
Primary, so the first option, or option A
Answer:
GENES
"genes contain the information needed to make functional molecules called proteins"
the manual is a gene
the bricks are amino acids
and the structures are proteins
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
