Question #1
The voice box or sound-producing organ in humans is the:
A. Trachea
B. Pharynx
C. Bronchi
D. Larynx

Correct Answer: Option D


Explanation:
The larynx, also called the voice box, contains vocal cords that vibrate as air passes, producing sound. It is located at the top of the trachea. The trachea (windpipe) conducts air; pharynx is the common passage for food and air; bronchi lead to lungs. The larynx is cartilaginous, and in males, the thyroid cartilage forms the Adam's apple.

Question #2
In a monohybrid cross between two heterozygous pea plants (Tt), the phenotypic ratio of tall to dwarf in the offspring is expected to be:
A. 1:1
B. 9:3:3:1
C. 1:2:1
D. 3:1

Correct Answer: Option D


Explanation:
When both parents are heterozygous (Tt × Tt), the offspring genotypes are TT (25%), Tt (50%), and tt (25%). Since tall (T) is dominant over dwarf (t), both TT and Tt are tall, resulting in 3 tall : 1 dwarf phenotypic ratio. The genotypic ratio is 1:2:1. 9:3:3:1 is the dihybrid phenotypic ratio. 1:1 ratio is seen in test cross (Tt × tt).
