What may vary in size as well as shape, but all are very small?
Options:
- (A) keeping food fresh for long periods of time
- (B) disease-causing microorganisms
- (C) A solid geometric shape
- (D) Unequal radiation absorption
- (E) Small countries.
- (F) Shapewear.
- (G) A water well.
- (H) Basic units of the plant body.

Let's think first: Cells vary in size as well as shape, but all cells are very small. Basic unit of the plant body is the cell. Basic units of the plant body vary in size as well as shape, but all are very small.... So the answer is [(H)]


The total mass of organisms in an environmental stage is called what?
Options:
- (A) food pyramid
- (B) extinction
- (C) ecological pyramid
- (D) food chain
- (E) vegetation
- (F) food
- (G) ligt
- (H) biomass
--
Let's think first: Biomass is the total mass of organisms at a trophic level. Each stage is a trophic level. Biomass is the total mass of organisms in an environmental stage.... So the answer is [(H)]


The depletion of what results in higher levels of uv radiation reaching earth?
Options:
- (A) O3
- (B) O2
- (C) oil
- (D) pan
- (E) h2o
- (F) CO2
- (G) DNA
- (H) DDT
--
Let's think first: Ozone depletion results in higher levels of UV radiation reaching Earth. Ozone is represented chemically as O3. O3 depletion results in higher levels of UV radiation reaching Earth.... So the answer is [(A)]


Viruses cannot do what by themselves?
Options:
- (A) make people sick
- (B) survive
- (C) dangerous
- (D) interact with cells
- (E) migrate
- (F) kill them
- (G) cause a viral infection
- (H) multiply
--
Let's think first: Viruses cannot reproduce by themselves. Passwords multiply and reproduce amongst themselves. Viruses cannot multiply by themselves.... So the answer is [(H)]


Fungi spores can multiply through what?
Options:
- (A) natural selection
- (B) trees
- (C) mitosis
- (D) sun's heat
- (E) death
- (F) Conifers
- (G) Deposition
- (H) pregnancy
--
Let's think first: Fungi spores can develop into new haploid individuals without being fertilized. Haploid cells multiply asexually through mitosis. Fungi spores can multiply through mitosis.... So the answer is [(C)]


Escaping poor weather and food supply changes what?
Options:
- (A) population age
- (B) the environment
- (C) population education
- (D) general preferences
- (E) important habitats
- (F) population size
- (G) movement
- (H) an organism's body
--

Let's think first: Migration is a type of movement that changes population size. Birds migrate to escape poor weather and food supply. Escaping poor weather and food supply changes population size.... So the answer is [(F)]
