Logic of a solution: *Fungi lack chlorophyll, so they cannot make food by photosynthesis as plants can. Fungi decompose dead plant and animal matter. Since fungi cannot make food by photosynthesis, they decompose dead organisms.*
*(B)*
The original question: *Where do fungi get their food?
Options:
- (A) swamp vegetation
- (B) decomposing dead organisms
- (C) decomposition
- (D) the environment
- (E) mushrooms
- (F) By wind and rain
- (G) spores
- (H) carbon dioxide*

Line 1: *Echinoderms lack respiratory and excretory systems. Echinoderms are represented by the starfish. Starfish lack respiratory and excretory systems.*
*(G)*
Line 2: *_ lack respiratory and excretory systems.
Options:
- (A) graptolites
- (B) insects
- (C) ferns
- (D) barnacles
- (E) fossil fuels
- (F) Allergies
- (G) starfish
- (H) parasites*

Logic of a solution: *Alternation of generations allows for both asexual and sexual reproduction. Reproduction Organisms create young of their species by reproduction. Alternation of generations allows for creating young by asexual and sexual means.*
*(H)*
The original question: *What allows for an organism to create young by sexual and asexual means?
Options:
- (A) spread flower seeds
- (B) remains of prehistoric life
- (C) peachleaf willow
- (D) photosynthesis
- (E) mate with females
- (F) members of their own species
- (G) A compound that donates proton
- (H) alternation of generations*

Line 1: *Most genes contain the instructions for a single protein. Alleles are alternative forms of a gene. Alleles can contain instructions for making alternative versions of the same single protein.*
*(A)*
Line 2: *Alternative instructions for a single protein are encoded on:
Options:
- (A) alleles
- (B) Acids
- (C) PDAs
- (D) nucleus
- (E) junk DNA
- (F) A computer
- (G) inheritance
- (H) Tail*

Logic of a solution: *Fertilization occurs when a sperm and an egg fuse to form a diploid zygote. Sexual reproduction requires formation of gametes, followed by fertilization. Sexual reproduction involves a sperm and egg fusing to form a diploid zygote.*
*(D)*
The original question: *What involves a sperm and egg fusing to form a diploid zygote?
Options:
- (A) Leptospirosis
- (B) produce offspring
- (C) allow growth
- (D) sexual reproduction
- (E) metabolic reaction
- (F) peachleaf willow
- (G) rapid expansion
- (H) Plant reproduction*

Logic of a solution: *Lymphocytes are the key cells involved in the immune response. An allergy attack is an immunal response. Lymphocytes are the key cells involved in an allergy attack.*
*(B)*
The original question:
*What are the key cells in an allergy attack?
Options:
- (A) layers of fat
- (B) Lymphocytes.
- (C) fur and fat
- (D) bone cells
- (E) muscle cells
- (F) the skin
- (G) Red blood cells
- (H) animals*
