What is one of the facets of an organism's evolution?
Options:
- (A) resistance
- (B) fitness
- (C) properties
- (D) thirst
- (E) movement
- (F) swimming
- (G) offspring
- (H) recycling
--
Let's think first: Behaviors that improve fitness increase through natural selection. Many organism behaviors have evolved through natural selection. An organism's fitness is a result of evolution.... So the answer is [(B)]

What can dna contain the instructions for?
Options:
- (A) keeps the organism warm
- (B) Something to move
- (C) Plant reproduction
- (D) a single protein
- (E) A computer
- (F) Animal survival
- (G) survival
- (H) an engine
--
Let's think first: Most genes contain the instructions for a single protein. Genes are made of DNA, the substrate of hereditary information. DNA can contain the instructions for a single protein.... So the answer is [(D)]
------
Cartilage is a tough tissue made up of:
Options:
- (A) a cuticle
- (B) bones
- (C) Joules
- (D) neurons
- (E) the skin
- (F) loose soil
- (G) fibrils
- (H) muscle
--
Let's think first: Cartilage is a tough tissue that contains a protein called collagen. Many collagen fibrils come together and form a collagen and forma collagen fiber. Cartilage is a tough tissue made up of fibrils.... So the answer is [(G)]
------
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)]
