A mutation that changes a codon from one amino acid to a different amino acid is called a:
Answer: Missense mutation
A missense mutation results in a codon that codes for a different amino acid, potentially altering protein function.
Which of the following is a characteristic unique to Kingdom Fungi compared to Kingdom Plantae?
Answer: Cell walls made of chitin
Fungi have cell walls composed of chitin, whereas plant cell walls are made of cellulose.
In the Hardy-Weinberg equation p² + 2pq + q² = 1, what does '2pq' represent?
Answer: Frequency of the heterozygous genotype
The term 2pq represents the frequency of heterozygous individuals in a population at Hardy-Weinberg equilibrium.
Which of the following would NOT disrupt Hardy-Weinberg equilibrium?
Answer: Random mating in a large population
Hardy-Weinberg equilibrium requires random mating; it is a condition that maintains equilibrium, not one that disrupts it.
An organism that obtains energy by oxidizing inorganic compounds such as ammonia or hydrogen sulfide is called a:
Answer: Chemoautotroph
Chemoautotrophs use energy from oxidizing inorganic compounds and fix carbon dioxide as their carbon source.
What type of inheritance pattern is shown when the expression of one gene depends on the presence of a specific allele at a different gene locus?
Answer: Epistasis
Epistasis occurs when the expression of one gene is masked or modified by an allele at a different locus.
Which phylum contains animals with a true coelom, segmented body, and a closed circulatory system?
Answer: Annelida
Annelids (segmented worms such as earthworms) have a true coelom, segmented bodies, and a closed circulatory system.
