Options:
- (A) h2o
- (B) urea
- (C) CO2
- (D) beds
- (E) houses
- (F) air
- (G) NaCl
- (H) H20
--
Let's think first: Most people can survive only a few days without water. H20 Bottled water was generally consumed last year. Most people can survive only a few days without H20.... So the answer is [(H)]

Sweat cools the body when it
Options:
- (A) Movement of an air mass
- (B) dry conditions
- (C) heat produced
- (D) Decreased precipitation
- (E) hydration
- (F) It expands
- (G) the environment
- (H) turns into a gas
--
Let's think first: Sweat wets the skin, and when it evaporates, it cools the body. Evaporation is when a liquid turns into a gas. Sweat cools the body when it turns into a gas.... So the answer is [(H)]

What type of acid contains inherited instructions for proteins?
Options:
- (A) HIV
- (B) p53
- (C) genetic acids
- (D) DNA
- (E) SNPs
- (F) protein acid
- (G) RNA
- (H) two
--
Let's think first: DNA contains genetic instructions for proteins, and RNA helps assemble the proteins. Genetic memory is inherited. DNA contains inherited instructions for proteins.... So the answer is [(D)]

Where in the plant does growth in width or girth originate?
Options:
- (A) conductive tissue
- (B) carbon dioxide
- (C) Veins and arteries.
- (D) It gets more light
- (E) photosynthesis
- (F) at or near the margins
- (G) vascular tissue
- (H) in the autumn season
--
Let's think first: Secondary meristem is located within and around the vascular tissues. Growth in girth is caused by other meristems, called secondary meristems. Plant growth in width or girth emanates from within and around the vascular tissues.... So the answer is [(G)]

What is a major route of removing wastes from the body?
Options:
- (A) Detoxifying teas
- (B) Feces
- (C) Burping
- (D) Essential Oils
- (E) glucose
- (F) sodium
- (G) NaCl
- (H) rivers
--
Let's think first: Excretion is the process of removing wastes and excess water from the body. Major route of excretion is in the feces. Feces are a major route of removing wastes and excess water from the body.... So the answer is [(B)]

What creates active immunity from a parasite?
Options:
- (A) Cooking
- (B) memory cells
- (C) alpacas
- (D) peachleaf willow
- (E) Allergies
- (F) mammals
- (G) an organism's body
- (H) animals
--
Let's think first: Active immunity results when an immune response to a pathogen produces memory cells. If the parasite causes harm, it is a pathogen. When a parasite produces memory cells, active immunity results.... So the answer is [(B)]
