Which of the following terms is mismatched?
phenotype -- how you express your genes
allele -- alternative forms of a gene
homozygous -- having two different alleles for a trait
genotype -- the two distinct genes you have for a trait
Incomplete Dominance - two alleles blend together in expression
The Correct Answer is C
A. phenotype – how you express your genes: Match. Phenotype is the physical or observable expression of your genes.
B. allele – alternative forms of a gene: Match. Alleles are different versions of the same gene (e.g., dominant vs. recessive).
C. homozygous – having two different alleles for a trait: Match. Homozygous means two same alleles (e.g., AA or aa). This definition describes heterozygous.
D. genotype – the two distinct genes you have for a trait: Match. Genotype is the combination of alleles (e.g., Aa or AA) you inherit.
E. Incomplete Dominance – two alleles blend together in expression: Match. In incomplete dominance, neither allele is fully dominant, resulting in a blended phenotype.

Correct Answer is B
Explanation
A. it requires heat to evaporate: Water has a high heat of vaporization, meaning it requires a lot of energy to evaporate.
B. it undergoes rapid temperature changes: Water has a high specific heat, meaning it resists rapid temperature changes, which helps maintain homeostasis.
C. it is an excellent solvent: Water is called the "universal solvent" due to its polarity, which dissolves many substances.
D. it is a great mixing medium, forming solutions, suspensions and colloids: Water forms various types of mixtures, including solutions, suspensions, and colloids.
Correct Answer is C
Explanation
A. a colloid: A colloid has larger particles than a solution, but they do not settle out (e.g., milk).
B. a solution: In a solution, particles are completely dissolved and remain evenly distributed (e.g., salt water).
C. a suspension: In a suspension, particles are large, do not dissolve, and will settle out over time (e.g., muddy water).
D. a solute: A solute is a substance dissolved in a solvent-not a type of mixture.
