Oncogenes promote the division of cells using the damaged form of what?
Options:
- (A) deoxyribonucleic acid
- (B) oncogenes
- (C) proteins
- (D) Chemical energy
- (E) epidermis and dermis
- (F) the body's largest organ
- (G) Veins and arteries.
- (H) healthy cells
--
Let's think first: Oncogenes promote the division of cells with damaged DNA. DNA DNA is deoxyribonucleic acid. Oncogenes promote the division of cells with damaged deoxyribonucleic acid.... So the answer is [(A)]

An overheated body can use water for:
Options:
- (A) metabolic reaction
- (B) dehydrating
- (C) raising their temperature
- (D) heat produced
- (E) liquid
- (F) watering plants
- (G) evaporative cooling
- (H) retaining heat
--
Let's think first: Sweat wets the skin, and when it evaporates, it cools the body. Sweat is made of salt and water. The evaporation of water from the skin cools the body.... So the answer is [(G)]

What is one way billions of seeds be spread by?
Options:
- (A) wind
- (B) manufactured goods
- (C) fossilization
- (D) maples
- (E) range
- (F) Seesaw
- (G) hail
- (H) trees
--
Let's think first: Spores may be dispersed by moving water, wind, or other organisms. Billions of spores can be produced on a single spore horn. Billions of seeds can be spread by moving wind, other organisms, or water.... So the answer is [(A)]

What do fungi lack that make them unable to make food as producers can?
Options:
- (A) scattered light
- (B) chlorophyll
- (C) Energy.
- (D) sunlight
- (E) Energy
- (F) acetic acid
- (G) Chemical energy
- (H) energy usage
--
Let's think first: Fungi lack chlorophyll, so they cannot make food by photosynthesis as plants can. If the plant is green, it is a producer. Fungi lack chlorophyll, so they cannot make food by photosynthesis as producers can.... So the answer is [(B)]

Which animal has a backbone?
Options:
- (A) camels
- (B) snail
- (C) bats
- (D) cricket
- (E) a fish
- (F) bird
- (G) koalas
- (H) octopus
--
Let's think first: Birds are endothermic tetrapod vertebrates. Animals with backbones are called vertebrates. All birds have backbones.... So the answer is [(F)]

What are viruses not?
Options:
- (A) self-copies
- (B) an object
- (C) HIV
- (D) humans
- (E) infectious
- (F) homogenous
- (G) dangerous
- (H) prokaryotes
--
Let's think first: Populations of viruses do not grow through cell division because they are not cells. Prokaryotes multiply by simple cell division, forming clones or exact copies of themselves. Viruses are not prokaryotes.... So the answer is [(H)]
