Question 1

Which of the following biological processes correctly distinguishes excretion from egestion in living organisms?

Excretion is the elimination of undigested dietary fiber through the anus, whereas egestion removes toxic cellular products. Excretion involves only the loss of water vapour through the skin, while egestion is the removal of mineral salts through the kidneys. Excretion is the removal of toxic metabolic waste products formed inside body cells, whereas egestion is the expulsion of undigested food materials from the alimentary canal. Excretion occurs exclusively in plants through stomata, whereas egestion occurs exclusively in animals through specialized excretory organs.

Correct Answer:

Excretion is the removal of toxic metabolic waste products formed inside body cells, whereas egestion is the expulsion of undigested food materials from the alimentary canal.

Question 2

According to the binomial system of nomenclature developed by Carl Linnaeus, which of the following is the correct scientific format for writing the name of the common housefly?

Musca domestica (with the genus capitalized and specific epithet in lowercase, italicized or underlined) musca Domestica (with the genus in lowercase and specific epithet capitalized) Musca Domestica (with both genus and specific epithet capitalized) musca domestica (with both genus and specific epithet in lowercase and unitalicized)

Correct Answer:

Musca domestica (with the genus capitalized and specific epithet in lowercase, italicized or underlined)

Question 3

A microscopic unicellular organism is isolated from stagnant water in Buea. Electron microscopy reveals that it contains circular DNA free in the cytoplasm, a peptidoglycan cell wall, and 70S ribosomes, but completely lacks a nuclear membrane and membrane-bound organelles.

Correct Answer:

Kingdom Monera (Prokaryotae)

Question 4

Which combination of characteristics distinguishes organisms in Kingdom Fungi from organisms in Kingdom Plantae?

Fungi possess chloroplasts and autotrophic nutrition, whereas plants have chitinous cell walls. Fungi possess cellulose cell walls and store starch, whereas plants store glycogen. Fungi are exclusively unicellular prokaryotes, whereas plants are multicellular eukaryotes. Fungi have cell walls made of chitin, lack chlorophyll, and exhibit heterotrophic saprophytic nutrition, whereas plants have cellulose walls and are autotrophic.

Correct Answer:

Fungi have cell walls made of chitin, lack chlorophyll, and exhibit heterotrophic saprophytic nutrition, whereas plants have cellulose walls and are autotrophic.

Question 5
