Document Summary

Classifications (8: species, genus, family, order, class, phylum, kingdom, domain. Levels of biological organization (11: atom, molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere. Properties of a living organism (7: order, regulation, growth & development, energy utilization, response to the environment, evolution, reproduction. Steps of the scientific method: observations, question, hypothesis, prediction, test, supports hypothesis: make additional predictions and test them, does not support hypothesis: revise hypothesis or pose a new one. Hypothesis a tentative answer to some question; an explanation on trial. Prediction what you think will happen in an experiment. Theory much broader in scope than a hypothesis; only becomes widely accepted if they are supported by extensive evidence. Dependent variable one that is observed/measured in the experiment. Controlled variable one that is unchanged during an experiment. Element substance that cannot be broken down into other substances. Isotope alternate mass forms of an element: same number of protons and electrons, different number of neutrons.

b. The most inclusive of these taxonomic groups is Chordata.

c. The genus Homo might have as many species as are in the entire family Pongidae.

d. There can be no other species in the genus Homo.

e. All mammals must be Chordates.

2. Endotherms differ from ectotherms in that:

b. An endotherm's metabolic rate is not affected by temperature whereas the metabolism of an ectotherm has a Q10 of 2-3.

c. Endotherms are vertebrates and ectotherms are invertebrates.

d. On average, endotherms are much better sprinters (i.e., can run faster for short distances) than ectotherms.

c. 2.2

d. 2.5

e. none of these are correct.

4. What is the best description of how evolution by selection (natural or artificial) works?

a. mutation generates variation randomly, sex makes new combinations of genes randomly, and selection picks the best ones for reproduction.

b. selection leads to non-random mutation to make useful new alleles, which are then combined by sex.

c. exposure to environmental factors leads to non-random mutations that improve fitness.

d. through selection, mutations occur in those genes that will improve fitness.

e. mutation generates random new alleles, and sex combines them in ways that select the best for future generations.

b. Mutation is sufficient to produce considerable genetic variation between different tissues in an individual.

c. Senescence is defined by slow, constant decline in survival as individuals get older.

d. Different cell types are formed when different but specific portions of the zygoteâs DNA are lost from the different germ layers during development.

e. In an individual, the only cells that differ genetically from other cells are gametes.

a. Jaws evolved from paired appendages, which in turn evolved because they improved swimming ability.

b. Legs evolved from fins after early fishlike vertebrates invaded the land.

c. Jaws and inner ear bones evolved from gill arches, and leglike appendages evolved under selection for aquatic locomotion.

d. Viviparity (giving birth to well-developed young instead of laying eggs) was vital to the ability to reproduce on land without returning to the water.

9. You are a Peace Corps volunteer physician in a developing country. You notice that some of the villages you visit have a high incidence of a parasitic disease, but other nearby villages are unaffected. Investigating you find the villages with disease are in wet areas with lots of snails and frogs, while the disease-free villages are in drier places but have lots of insects and mice. From this information, what might you reasonably conclude about the type of parasite responsible for the disease?

a. Itâs a trematode (these need mollusks as intermediate hosts).

b. Itâs a nematode (these are vectored mainly by frogs).

c. Itâs an apicomplexan parasite (these require wet areas and enter the skin through standing water).

d. Itâs a trypanosome (these are transmitted by mammal bites).

e. The information doesnât provide useful clues about the type of parasite.

10. Which of the following pairs of primary diagnostic characters is correctly matched with taxonomic groups?

a. circulatory system vs. water vascular system: Nematoda vs. Echinodermata
