The next generation of an organism rises via:
Options:
- (A) Plants growth
- (B) spontaneous generation
- (C) reproduction
- (D) The Sun
- (E) revolution
- (F) sun's heat
- (G) heat energy
- (H) unions
--
Let's think first: Reproduction is the process by which organisms give rise to offspring. Then, the lowest energy offspring are used as parents for the next generation. Reproduction is the process by which organisms give rise to the next generation.... So the answer is [(C)]

Protonemas develop into what?
Options:
- (A) alveoli
- (B) ferns
- (C) lmestone
- (D) disease
- (E) illness
- (F) parasites
- (G) gas
- (H) spores
--
Let's think first: Flowers produce spores that develop into gametophytes. Gametophytes arise from a protonema. Flowers produce spores from a protonema.... So the answer is [(H)]

Tumors are a collection of cancer what?
Options:
- (A) harmful
- (B) mutations
- (C) cells
- (D) toxins
- (E) three
- (F) Mass
- (G) oncogenes
- (H) ovaries
--
Let's think first: Cancer cells divide more often than normal cells, and grow out of control. Cancer cells, however, grow out of control and develop into a tumor. Cancer cells divide more often than normal cells, and often develop into tumors.... So the answer is [(C)]

Mutation leads to _.
Options:
- (A) Devolution
- (B) Plants growth
- (C) rapid expansion
- (D) Evolution.
- (E) Degeneration
- (F) Extinction
- (G) massive damage
- (H) anemia
--
Let's think first: Mutation creates new genetic variation in a gene pool. Genetic variation is the raw material for evolution. Mutation leads to evolution.... So the answer is [(D)]

What is the form of genetic material used during mitosis called?
Options:
- (A) proteins
- (B) Plants growth
- (C) genetic fluid
- (D) mitosis cells
- (E) chromosomes
- (F) pollen
- (G) Leptospirosis
- (H) Chemical energy
--
Let's think first: Chromosomes are the form of the genetic material of a cell during cell division. Mitosis is cell division. Chromosomes are the form of the genetic material of a cell during mitosis.... So the answer is [(E)]

Most ecosystems need what?
Options:
- (A) invasive species
- (B) water
- (C) insects
- (D) food
- (E) tornadoes
- (F) recycling
- (G) plants
- (H) scientists
--
Let's think first: Most ecosystems get energy from sunlight. Sunlight is turned into energy by plants. Most ecosystems need plants.... So the answer is [(G)]
