Options:
- (A) alveoli
- (B) fusion
- (C) embryos
- (D) teats
- (E) rings
- (F) pollen
- (G) food
- (H) eyes
--
Let's think first: Monotremes are mammals that reproduce by laying eggs. Unlike most mammals, female monotremes have no teats. Female monotremes reproduce by laying eggs and have no teats.... So the answer is [(D)]

Arthropods have a life cycle with what?
Options:
- (A) rapid expansion
- (B) survival
- (C) aerobic capacity
- (D) food and shelter
- (E) an organism's body
- (F) reproduce
- (G) barnacles
- (H) mixing genes up
--
Let's think first: Arthropods have a life cycle with sexual reproduction. Sexual reproduction mixes the genes up more than is possible with asexual reproduction. Arthropods have a life cycle with mixing genes up.... So the answer is [(H)]

- (B) vaporization
- (C) hydrogen bonds
- (D) helium bonds
- (E) mysterious forces
- (F) nitrogen bonds
- (G) Physical weathering
- (H) precipitation
--
Let's think first: Hydrogen bonds cause water to expand when it freezes. Water is everywhere H20. Hydrogen bonds cause H20 to expand when it freezes.... So the answer is [(C)]

- (B) photons
- (C) voltage
- (D) sexually
- (E) Energy
- (F) bioaerosols
- (G) waves
- (H) food
--
Let's think first: Mollusks reproduce sexually. Interestingly, a squid is also a mollusk. Squids produce sexually.... So the answer is [(D)]

- (B) trust accounts
- (C) animals
- (D) babies
- (E) cremation
- (F) clothing
- (G) cancer
- (H) offspring
--
Let's think first: Cancer genes can be inherited. Children inherit from their parents. Cancer genes can be passed on by parents.... So the answer is [(G)]
