Question #1
In a cross between a homozygous dominant plant (TT) and a heterozygous plant (Tt), what proportion of the offspring will show the recessive phenotype?
A. 50%
B. 25%
C. 0%
D. 100%

Correct Answer: Option C


Explanation:
Cross: TT × Tt. Gametes: T (from TT) and T or t (from Tt). Offspring genotypes: TT and Tt. Both express the dominant phenotype because the recessive allele t is masked by T. No tt offspring are produced, so 0% show the recessive trait.

Question #2
Which characteristic is exclusive to living organisms and not observed in non-living entities?
A. Magnetism
B. Consciousness
C. Increase in mass
D. Crystallization

Correct Answer: Option B


Explanation:
Consciousness is the defining property of living organisms, allowing them to sense and respond to stimuli. Non-living objects can increase in mass (e.g., crystal growth), crystallize, or exhibit magnetism, but they lack consciousness. Reproduction and metabolism are also key characteristics, but consciousness is the most fundamental feature. Thus, only living things possess this ability.
