Class, Order, and Family are standard taxonomic ranks used in biological classification. Group is a general term, not a specific rank.
Question 2
Which of these organelles is typically found in plant cells but not animal cells?
Mitochondrion
Ribosome
Nucleus
Cell Wall
✓
Correct Answer
Cell Wall
Mitochondrion, Ribosome, and Nucleus are found in both plant and animal cells. A Cell Wall is characteristic of plant cells but is absent in animal cells.
Question 3
Which of these is not a type of lipid?
Steroid
Phospholipid
Starch
✓
Triglyceride
Correct Answer
Starch
Triglyceride, Steroid, and Phospholipid are all types of lipids. Starch is a polysaccharide, which is a type of carbohydrate.
Question 4
Which of these organisms is not a primary consumer?
Cow
Rabbit
Wolf
✓
Grasshopper
Correct Answer
Wolf
Cows, Rabbits, and Grasshoppers are primary consumers (herbivores) because they feed directly on producers. A Wolf is a secondary or tertiary consumer (carnivore).
Question 5
Which of these organelles is not surrounded by a membrane?
Ribosome
✓
Nucleus
Endoplasmic Reticulum
Mitochondrion
Correct Answer
Ribosome
The Nucleus, Endoplasmic Reticulum, and Mitochondrion are all membrane-bound organelles. Ribosomes are not surrounded by a membrane.
Question 6
Which of these is not a monomer for a larger biomolecule?
Fatty Acid
Protein
✓
Amino Acid
Glucose
Correct Answer
Protein
Glucose, Amino Acid, and Fatty Acid are monomers that can be linked to form larger biomolecules (polysaccharides, proteins, and lipids, respectively). Protein is a polymer, not a monomer.
Question 7
Which of these is not a kingdom of life?
Chordata
✓
Fungi
Plantae
Animalia
Correct Answer
Chordata
Animalia, Plantae, and Fungi are three of the established biological kingdoms. Chordata is a phylum within the Kingdom Animalia.
Question 8
Three of these are abiotic components of an ecosystem. Which one is not?
Bacteria
✓
Water
Soil pH
Temperature
Correct Answer
Bacteria
Water, Temperature, and Soil pH are abiotic (non-living) components of an ecosystem. Bacteria are biotic (living) components.
Question 9
Which of these organelles does not contain its own DNA?
Golgi Apparatus
✓
Chloroplast
Nucleus
Mitochondrion
Correct Answer
Golgi Apparatus
Mitochondria, Chloroplasts, and the Nucleus all contain their own genetic material (DNA). The Golgi Apparatus does not contain DNA.
Question 10
Which of these biomolecules does not typically contain nitrogen?
Protein
ATP
Nucleic Acid
Carbohydrate
✓
Correct Answer
Carbohydrate
Proteins (amino acids), Nucleic Acids (nitrogenous bases), and ATP (adenine) all contain nitrogen. Carbohydrates are primarily composed of carbon, hydrogen, and oxygen.
Question 11
Three of these scientific names are incorrectly formatted under binomial nomenclature. Which one is not?
Homo Sapiens
Canis familiaris
✓
Escherichia Coli
felis Catus
Correct Answer
Canis familiaris
'felis Catus', 'Homo Sapiens', and 'Escherichia Coli' are incorrectly formatted. The genus name should be capitalized, the species name should be lowercase, and both should be italicized. 'Canis familiaris' follows these rules.
Question 12
Three of these organisms are consumers or decomposers. Which one is not?
Hawk
Deer
Algae
✓
Mushroom
Correct Answer
Algae
Mushrooms (decomposers), Deer (primary consumers), and Hawks (secondary/tertiary consumers) are not producers. Algae are producers, capable of photosynthesis.
Question 13
Which of these organelles is not directly involved in protein synthesis or modification?
Golgi Apparatus
Ribosome
Lysosome
✓
Endoplasmic Reticulum
Correct Answer
Lysosome
Ribosomes synthesize proteins, the Endoplasmic Reticulum modifies and transports them, and the Golgi Apparatus further modifies, sorts, and packages them. Lysosomes are primarily involved in waste breakdown and recycling.
Question 14
Which of these biomolecules is not primarily known for storing or transmitting genetic information?
mRNA
Protein
✓
DNA
RNA
Correct Answer
Protein
DNA, RNA, and mRNA are all primarily involved in storing or transmitting genetic information. Proteins have diverse functions, including structural, enzymatic, and transport roles, but are not primarily known for genetic information storage or transmission.
Question 15
Which of these is not a kingdom within the Domain Eukarya?
Plantae
Animalia
Protista
Bacteria
✓
Correct Answer
Bacteria
Plantae, Animalia, and Protista are kingdoms within the Domain Eukarya. Bacteria is a separate domain of life, distinct from Eukarya.
