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 E
Explanation
A. presence of enzymes: Enzymes are biological catalysts that speed up reactions by lowering activation energy.
B. decreased concentration of reactants: Lower concentration means fewer collisions between molecules, which slows reaction rate.
C. lower activation energy: Lowering the activation energy makes it easier for reactants to form products, increasing reaction rate.
D. A & B: While A is correct, B is not.
E. A & C: Both enzymes and reduced activation energy increase reaction speed.
Correct Answer is B
Explanation
A. exocytosis: This is the process of expelling material out of the cell, not taking it in.
B. pinocytosis: Pinocytosis is "cell drinking"-the process of engulfing dissolved particles in fluid by invagination of the plasma membrane.
C. cytolysis: Cytolysis refers to cell bursting, not intake of particles.
D. phagocytosis: Phagocytosis is "cell eating", where the cell engulfs large solid particles like bacteria, not liquids.
