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 A
Explanation
A. from Side A to Side B: Osmosis is the movement of water from a region of lower solute concentration (10%) to one of higher solute concentration (20%) to equalize the concentration.
B. from Side B to Side A: This would occur only if Side A had a higher solute concentration, which it doesn't.
C. there will be no movement of water: There’s a concentration gradient, so water will move.
D. water will move from B to A and A to B at equilibrium: Equilibrium implies equal concentrations, which is not the case initially.
Correct Answer is C
Explanation
A. isotope; 27: The atomic number (27) refers to the number of protons, not neutrons. Isotopes have the same protons, different neutrons.
B. isomer; 33: An isomer is a different structural arrangement of the same molecules-not applicable here.
C. isotope; 33: Cobalt 60 is an isotope of Cobalt 59 (same protons, different neutrons).
Neutrons = mass number – atomic number = 60 – 27 = 33
D. isotope; 32: 60 – 27 = 33, not 32 neutrons.
