- (A) thorax
- (B) glomerulus
- (C) organ
- (D) arteries
- (E) layers of fat
- (F) more abundant
- (G) pancreas
- (H) urine
--
Let's think first: Nephrons are the structural and functional units of the kidneys. Each nephron has a glomerulus. Glomerulus is part of the kidney structure.... So the answer is [(B)]

Damaged dna might benefit from:
Options:
- (A) resistance
- (B) cellular repair
- (C) mutagens
- (D) UV rays
- (E) recovery
- (F) radiation
- (G) Electrical energy
- (H) flow of electrons
--
Let's think first: Cells have multiple repair mechanisms to fix mutations in DNA. And if the damaged DNA is duplicated, it causes mutation. Cells have multiple repair mechanisms to fix damaged DNA.... So the answer is [(B)]

Options:
- (A) squid
- (B) goats
- (C) bats
- (D) mammals
- (E) toads
- (F) Birds
- (G) edible
- (H) a fish
--
Let's think first: Mollusks have a circulatory system with one or two hearts that pump blood. Interestingly, a squid is also a mollusk. Squid have a circulatory system with one or two hearts that pump blood.... So the answer is [(A)]

What can use photosynthesis?
Options:
- (A) fungi
- (B) grass
- (C) fish
- (D) vegetation
- (E) flowers
- (F) vertebrates
- (G) plant life
- (H) plants
--
Let's think first: Fungi lack chlorophyll, so they cannot make food by photosynthesis as plants can. Solar energy is absorbed by chlorophyll. Fungi cannot absorb solar energy and cannot make food by photosynthesis as plants can.... So the answer is [(E)]

Options:
- (A) Cooking
- (B) Deposition
- (C) grow
- (D) It expands
- (E) reproduce
- (F) budding
- (G) heat
- (H) migrate
--
Let's think first: Yeast reproduce asexually by budding. Yeast, which is a type of fungus, is used by bakers to make traditional bread. Bread baking fungus reproduce asexually by budding.... So the answer is [(F)]

What disrupts the cycle between organisms and the atmosphere?
Options:
- (A) burning coal
- (B) Sulfur dioxide
- (C) replanting forests
- (D) solar system
- (E) Greenhouse gasses
- (F) chlorofluorocarbons
- (G) life cycle
- (H) deforestation
--
Let's think first: Carbon cycles quickly between organisms and the atmosphere. Deforestation also disrupts the Carbon Cycle. Deforestation disrupts the cycle between organisms and the atmosphere.... So the answer is [(H)]
