Options:
- (A) heat produced
- (B) Eating a lot
- (C) Reproducing quickly
- (D) biological diversity
- (E) vegetation
- (F) Being in a cluster
- (G) Staying far apart
- (H) hydrate their cells
--
Let's think first: Organisms cluster around hydrothermal vents in the ocean floor. To survive, some organisms living near hydrothermal vents have formed close associations. Clusters form around hydrothermal vents to ensure survival.... So the answer is [(F)]

- (A) bacteria
- (B) archaea
- (C) animals
- (D) SO2
- (E) fungi
- (F) plants
- (G) complex
- (H) E. coli
--
Let's think first: Cell division is more complex in eukaryotes than prokaryotes. All plants are eukaryotes. Cell division is more complex in plants than prokaryotes.... So the answer is [(F)]


Where can cells bound by antibodies more likely be found?
Options:
- (A) critical organs
- (B) colder and wetter
- (C) the environment
- (D) Earth orbiting the Sun
- (E) Veins and arteries.
- (F) epidermis and dermis
- (G) on cancer cells
- (H) the skin
--
Let's think first: Antigens are found on cancer cells and the cells of transplanted organs. Antibodies bound to antigen are then measured by RCAT-based amplification of the associated DNA tag. Cells bound by antibodies can be found on cancer cells and the cells of transplanted organs.... So the answer is [(G)]


What is it called when one solvent combines with another, what forms?
Options:
- (A) chemical pair
- (B) permineralization
- (C) chemical bonds
- (D) a solute
- (E) chemical duo
- (F) substance bonds
- (G) Condensation
- (H) kinetic energy
--
Let's think first: Chemical bonds form when substances react with one another. Solvents are substances, usually liquid, that dissolve other substances. When one solvent reacts with another, chemical bonds form.... So the answer is [(C)]

Options:
- (A) matter
- (B) vital
- (C) omniscient
- (D) external
- (E) toads
- (F) food
- (G) always angry
- (H) animals
--
Let's think first: Organs of excretion make up the excretory system. All internal organs are vital organs. A thing that is internal and vital make up the excretory system.... So the answer is [(B)]

- (E) infected
- (F) dormant
- (G) cellular
- (H) protected
--
