Test on Evolution, Classification, and Genetic Principles

Question 1: Mitochondrial inheritance is best described as heritable changes in gene expression that do not involve alterations to the DNA sequence of mitochondria, similar to the process of epigenetics.

A. Ano

B. Ne

Explanation: Mitochondrial inheritance specifically refers to traits passed through maternal DNA. Epigenetics, on the other hand, describes heritable changes in gene expression without altering the DNA sequence. While both involve heredity, mitochondrial inheritance is about the direct transmission of mitochondrial DNA itself, not just changes in its expression without altering the sequence.

Question 2: According to the study materials, which of the following statements about Archaea and Bacteria classification is accurate?

A. Archaea are extremophiles characterized by unique cell walls.

B. Both Archaea and Bacteria are classified as prokaryotic kingdoms.

C. The Domain is a lower taxonomic rank than the Kingdom for these organisms.

D. They were part of the older five-kingdom model known as Protista.

Explanation: The study materials state that Archaea are extremophiles with unique cell walls. It also specifies that Archaea and Bacteria are prokaryotic kingdoms. Domains are described as the highest rank, not a lower one. The older five-kingdom model included Monera, Protista, Fungi, Plantae, and Animalia, but did not classify Archaea and Bacteria separately under Protista within that model.

Question 3: Plantae are photosynthetic multicellular organisms.

A. Ano

B. Ne

Explanation: Plantae are defined as photosynthetic multicellular organisms.

Question 4: Animalia are multicellular heterotrophs that are incapable of movement.

A. Ano

B. Ne

Explanation: Animalia are described as multicellular heterotrophs capable of movement in the provided materials.

Question 5: According to the study materials, what does 'Genotype' refer to?

A. Genetic composition

B. Organisms with nucleated cells

C. Multicellular heterotrophs capable of movement

D. The science of classification

Explanation: The study materials explicitly define 'Genotype' as 'Genetic composition'.
