What can prevent 90 percent of the body's heat loss?
Options:
- (A) Masks
- (B) fur
- (C) coats
- (D) bald head
- (E) increase body fat
- (F) sweaters
- (G) skin
- (H) hair
--
Let's think first: Head hair is especially important in preventing heat loss from the body. Almost 90 percent of the body's heat loss is from the head. Without hair, 90 percent of the body's heat would be lost.... So the answer is [(H)]


If not managed properly, nutrients can be depleted on
Options:
- (A) environment
- (B) Dehydration
- (C) fronts
- (D) our planet
- (E) coastlines
- (F) the skin
- (G) farmland
- (H) Power plants
--
Let's think first: Soil can be depleted of nutrients. Wampanucket soils are prime farmland soils. Farmland can be depleted of nutrients.... So the answer is [(G)]


What is needed from cells for phosphatases to keep the proper ph?
Options:
- (A) plasma
- (B) secretion of bases only
- (C) secretion of proteins
- (D) metabolic reaction
- (E) it helps plants in growing
- (F) Positive charges
- (G) Transfers energy
- (H) secretion of acids and bases
--
Let's think first: Cells secrete acids and bases to maintain the proper pH for enzymes to work. Phosphatases are enzymes that remove phosphates from other enzymes. Cells secrete acids and bases to keep the proper pH for phosphatases to work properly.... So the answer is [(H)]


Invertebrates can be what?
Options:
- (A) people
- (B) scarce resources
- (C) vertebrates
- (D) deposit feeders
- (E) Catch prey
- (F) major threat to health
- (G) more abundant
- (H) planets
--
Let's think first: Earthworms are important deposit feeders that help form and enrich soil. Earthworms by Casey Earthworms are invertebrates. Invertebrates can be deposit feeders.... So the answer is [(D)]


What is something that correlates with temperature change?
Options:
- (A) Lift
- (B) fronts
- (C) heat
- (D) wind
- (E) fever
- (F) sweat
- (G) Joules
- (H) stress
--
Let's think first: Temperature falls from lower to higher altitudes. Lift decreases with altitude. Lower temperatures align with lower lifts.... So the answer is [(A)]


What lives in water that contains little or no salt?
Options:
- (A) animals
- (B) terrapins
- (C) a fish
- (D) Chlorophyll
- (E) bacteria
- (F) sharks
- (G) sodium
- (H) humans
--

Let's think first: Freshwater biomes have water that contains little or no salt. Terrapins are freshwater turtles. Terrapins live in water that contains little or no salt.... So the answer is [(B)]
