College DNA, RNA, and Genetics
Assume that you have crossed orange flowered daisies with white flowered daisies. The offspring of these plants consists of 360 orange flowered daisies and 340 white flowered daisies. What can you conclude about this trait in daises?
  1. The gene for orange flowers is homozygous and the gene fo white flowers is also homozygous
  2. The gene for flower color in daises exhibits incomplete dominance
  3. The gene for orange flowers and the gene for white flowers are on the same chromosome.
  4. The gene for flower color in daisies exhibits complete dominance.
College DNA, RNA, and Genetics
What is a "locus"?
  1. The region of a chromosome where a particular gene can be found.
  2. The sequence of nucleotides that make up a codon.
  3. The area of a chromosome where the sister chromatids are connected to each other.
  4. The structure formed when a homologous pair of chromosomes line up together before Meiosis.
College DNA, RNA, and Genetics
What part of the production of gametes is explained by the Law of Independent Assortment?
  1. the separation of chromosomes during meiosis 2 so that each daughter cell contains a copy of every chromosome.
  2. the sorting of chromosomes during meiosis 1 so that each daughter cell contains a random selection of either maternal or paternal chromosomes from each homologous pair.
  3. the separation of sister chromatids during meiosis 1 so that each daughter cell contains half the number of original chromosomes.
  4. the sorting of sister chromatids during meiosis 2 so that each daughter cell contains twice the number of original chromosomes.

College Biology
The following are all considered ultraradian cycles, EXCEPT:
  1. Urinating
  2. Menstrual Cycle
  3. Surfing the Net
  4. Eating
College Taxonomy
Construction of phylogenetic trees (cladograms) is based on the assumption that
  1. new species are formed at a constant and predictable rate
  2. characteristics shared among species reflect descent from a common ancestor
  3. homologous features usually cannot be distinguished from analogous features
  4. most species frequently
College Anatomy and Physiology
The "all-or-none" law refers to the observation that an action potential
  1. will diminish to near zero when transmitted down a long axon.
  2. is conducted more rapidly down the axon as it reaches the axon terminal.
  3. is produced whenever the membrane potential reaches threshold.
  4. fires at the same rate regardless of the inputs to the neuron.
  5. travels only in one direction.

College Biochemical Pathways
During cellular respiration, oxygen
  1. delivers electrons to the destination known as the citric acid cycle.
  2. is chemically converted to ATP.
  3. delivers its electrons to the electron transport chain.
  4. is reduce to NADP+.
  5. acts the final electron acceptor.
College Skin, Skeleton, and Muscles
College Macromolecules
Select all those that are properties of a protein.
  1. The monomer an amino acid
  2. Among proteins functions are structure, defense, and breakdown of particles.
  3. Proteins act as catalysts.
  4. Amino acids are joined by peptide bonds.
  5. A long chain of amino acids is called a polypeptide.
College Anatomy and Physiology
