Alternative instructions for a single protein are encoded on:
Options:
- (A) alleles
- (B) Acids
- (C) PDAs
- (D) nucleus
- (E) junk DNA
- (F) A computer
- (G) inheritance
- (H) Tail
--
Let's think first: Most genes contain the instructions for a single protein. Alleles are alternative forms of a gene. Alleles can contain instructions for making alternative versions of the same single protein.... So the answer is [(A)]
What can fatty acids be combined with, in addition to carbon and oxygen?
Options:
- (A) Sodium
- (B) Energy.
- (C) glucose
- (D) Carbon Dioxide
- (E) Fuel cells
- (F) Uranium
- (G) Hydrogen
- (H) Energy
--
Let's think first: Lipids may consist of fatty acids alone, or they may contain other molecules as well. Lipids Lipids are also composed of carbon, oxygen and hydrogen. Carbon, oxygen, and hydrogen can be combined with fatty acids.... So the answer is [(G)]
Carbon monoxide, a product of furnaces and engines, is a:
Options:
- (A) acid
- (B) CO2
- (C) kill
- (D) harm
- (E) gas
- (F) form
- (G) CO 2
- (H) HPV
--
Let's think first: Carbon monoxide is a gas produced by furnaces and other devices that burn fuel. Fuel is burned inside the engine. Carbon monoxide is a gas produced by furnaces and other engines.... So the answer is [(E)]
What is a potential outcome of genetic mutation?
Options:
- (A) HIV
- (B) albino
- (C) anemia
- (D) pizza eating turtles
- (E) genealogy
- (F) SNPs
- (G) biology
- (H) death
--
Let's think first: Mutations may change the structure of a chromosome or just change a single nucleotide. SNPs involve polymorphisms at the single nucleotide level. Mutations may change the structure of a chromosome or just cause SNPs.... So the answer is [(F)]
What would a person do that would reduce their body heat?
Options:
- (A) using steel
- (B) Exfoliation
- (C) Evaporation
- (D) drink a warm drink
- (E) burning coal
- (F) perspire
- (G) exercise outside
- (H) take a nap
--
Let's think first: Sweating reduces body heat. People of all ages and activity levels perspire or sweat. Perspiration reduces body heat.... So the answer is [(F)]
Zooplankton are tiny animals that feed on what?
Options:
- (A) sunlight
- (B) vegetation
- (C) Energy
- (D) loose soil
- (E) plant life
- (F) diatoms
- (G) fungi
- (H) chemicals
--

Let's think first: Zooplankton are tiny animals that feed on phytoplankton. Diatoms are the predominant phytoplankton. Zooplankton are tiny animals that feed on diatoms.... So the answer is [(F)]
