What kind of plants produces their seeds in cones?
Options:
- (A) spored bushes
- (B) flowers
- (C) more abundant
- (D) Conifers
- (E) white
- (F) insects
- (G) evergreens
- (H) deciduous trees
--
Let's think first: Gymnosperms are vascular plants that produce seeds in cones. Gymnosperms are the plants that are known as evergreens. Evergreens are vascular plants that produce seeds in cones.... So the answer is [(G)]

The evolution of animal genetic resources can be impacted by:
Options:
- (A) extinction
- (B) Mars
- (C) competition
- (D) Darwin
- (E) agriculture
- (F) behavior
- (G) environment
- (H) Galapagos Islands
--
Let's think first: Behaviors that improve fitness increase through natural selection. Adaptation traits contribute to individual fitness and to the evolution of animal genetic resources. Behaviors can improve the evolution of animal genetic resources.... So the answer is [(F)]

The transfer of pollen to what is the fertilization step of the sexual reproduction of a plant?
Options:
- (A) stigma
- (B) apples
- (C) flowers
- (D) embryos
- (E) potatoes
- (F) seeds
- (G) eggs
- (H) plants
--
Let's think first: Pollination is the fertilization step in the sexual reproduction of plants. Pollination is the transfer of pollen grains to a stigma. The transfer of pollen grains to a stigma is the fertilization step in the sexual reproduction of plants.... So the answer is [(A)]

_ carry signals that control sexual development and reproduction.
Options:
- (A) photons
- (B) sex hormones
- (C) nerves
- (D) Most plants
- (E) organs
- (F) orchids
- (G) animals
- (H) insects
--
Let's think first: Sex hormones are chemical messengers that control sexual development and reproduction. Chemical messengers carry signals from one nerve branch to another. Sex hormones carry signals that control sexual development and reproduction.... So the answer is [(B)]

Ozone depletion results in radiation levels that are highest when?
Options:
- (A) middle of the day
- (B) forest is destroyed
- (C) late evening
- (D) Under 32 degrees
- (E) middle of the night
- (F) Temperature changing
- (G) Plant growth is reduced
- (H) early morning
--
Let's think first: Ozone depletion results in higher levels of UV radiation reaching Earth. Solar UV radiation levels are highest during the middle of the day. Ozone depletion results in radiation levels that are highest during the middle of the day.... So the answer is [(A)]

What is a form of vesicle transport that requires energy?
Options:
- (A) absorption
- (B) glucose
- (C) Leptospirosis
- (D) a solute
- (E) Energy.
- (F) bioaerosols
- (G) direct energy
- (H) heat or cold
--
Let's think first: Vesicle transport requires energy, so it is also a form of active transport. Absorption comes from active transport. Absorption is a form of vesicle transport that requires energy.... So the answer is [(A)]
