Question 1: Polygenic inheritance

Answer:

combined effect of two or more genes on a single character (Concept 10.3)

Question 2: Different invertebrate phylum

Answer:

(blank)

Question 3: Difference b/t phenotype and genotype

Answer:

• phenotype: observable traits of an organism (Concept 10.2) VS genotype: genetic makeup of an

organism; an organism's combination of alleles (Concept 10.2)

Question 4: Double helix

Answer:

two strands of nucleotides wound about each other; structure of DNA (Concept 11.2)

Question 5: Nucleotide

Answer:

: building block (monomer) of nucleic acid polymers (Concept 11.2)

Question 6: Codons/anticodons

Answer:

• codon: in RNA, a three-base "word" that codes for one amino acid (Concept 11.4) / anticodon: in

tRNA, a triplet of nitrogenous bases that is complementary to a specific codon in mRNA (Concept 11.5)

Question 7: Vestigial and homologous structures

Answer:

• vestigial structure: remnant of a structure that may have had an important function in a species'

ancestors, but has no clear function in the modern species (Concept 14.2) & homologous structure: similar structure found in more than one species that

Question 8: Binary fission

Answer:

• binary fission: mode of prokaryote asexual reproduction in which each daughter cell receives an

identical copy of the parent cell's chromosome (Concept 16.2)

Question 9: Intermediate inheritance

Answer:

inheritance in which heterozygotes have a phenotype intermediate between the phenotypes of the two homozygotes (Concept 10.3)

Question 10: Haploid Cell

Answer:

: having a single set of chromosomes (Concept 9.5)

Question 11: Micro vs. macroevolution

Answer:

• microevolution: evolution on the smallest scale-a generation-to-generation change in the

frequencies of alleles within a population (Concept 14.4) VS macroevolution: major biological changes evident in the fossil record (Concept 15.1)

Question 12: Pathogens

Answer:

: a disease-causing organism or virus (Concepts 16.4, 31.1)

Question 13: Xylem vs. Phloem

Answer:

• xylem: vascular tissue that transports water and dissolved minerals from the roots of a plant to the

shoots (Concept 20.2) VS phloem: vascular tissue that transports food from a plant's leaves to its roots and other parts (Concept 20.2)

Question 14: Flower Diagram

Answer:

(blank)

Question 15: Genetic linkage

Answer:

tendency for alleles of genes on the same chromosome to be inherited together (Concept 10.4)

Question 16: Genetic Linkage

Answer:

tendency for alleles of genes on the same chromosome to be inherited together (Concept 10.4)

Answer:

?

Question 18: Angiosperms vs Gymnosperms

Answer:

• angiosperm: flowering plant (Concept 19.5) VS gymnosperm: plant that bears seeds that are not

enclosed in an ovary (Concept 19.4)

Question 19: Sex chromosomes

Answer:

one of two chromosomes of the 23rd pair of human chromosomes, which determine an individual's gender (Concept 9.5)

inheritance pattern in which a heterozygote expresses the distinct traits of both alleles (Concept 10.3)

Question 25: Fermentation

Answer:

cellular process of making ATP without oxygen (Concept 7.6)

Question 26: Natural vs. artificial selection

Answer:

process by which individuals with inherited characteristics well-suited to the environment leave more offspring than do other individuals (Concepts 1.3, 14.1) VS artificial selection: selective breeding of domesticated plants and animals to produce offspr
