1) an elementary student decides to conduct an experiment comparing the effectiveness
of two commercial soaps as cleaning agents, using each in paired tests of different types
of stains and colors of cloth, where the only variable was the soap used. the student will
use the judgment of classmates to decide if the stains remain equal or if soap one cleans
better than the other in each test run. however, the student makes no prediction of which
soap is expected to perform best.
a. this lacks a hypothesis and is therefore not a scientific test.
b. this lacks any control group (no-soap treatment) and therefore will provide no
meaningful results.
c. because this is based on the subjective judgments of students, it is not objective and
therefore not scientific.
d this is a scientific procedure, although it does lack a stated hypothesis describing an
anticipated outcome.
e. this experimental design has all the components and procedures of the scientific

4) identify the correct order of steps in the development of the central nervous system.
a. neural folds develop on either side of the neural groove.
b. the neural tube forms.

b. there is an input of 6 carbons (2 pyruvates) and an output of 6 carbons (1 glucose)
c. there is an input of 6 carbons (glucose) and an output of 6 carbons (6 co2)
d. there is an input of 3 carbons (glucose) and an output of 3 carbons (pyruvate)

7) all of the following statements concerning the theory of continental drift are true
a. the coastlines of several continents are mirror images.
b. similar geological structures are found in areas where the continents touched.
c. continental drift has ceased.
d. the unique distribution patterns of several fossils is explained by continental drift.
8) which ocean current runs along the western coast of south america producing cold
offshore winds?
a. humboldt current
b. equatorial countercurrent
c. gulf stream
d. west wind drift current
e. east wind drift
9) as animals take in food energyapproximately 10% of it is made available to the next
level in the food chain.which of the following is one of the ways in which the energy is
used by the organism and not passed along?
a. cellular respiration
b. defecation
c. excretion
d. death
e. all of these are ways in which the organism uses the energy.
10) consider the following food chain: hawk - rabbit - clover. each species will contain
a different amount of calories in its body (clover: 10 calories, rabbit: 500 and hawk:
1200). each species has a different daily caloric requirement (clover: sunlight, rabbit:
100 calories, hawk: 300).
how many clover plants, per day,does it take to support a family of hawks (mom, dad
and juvenile. assume each hawk needs the same number of calories per day)?
a. approximately 1800 clover plants
b. approximately 600 clover plants
c. approximately 100 clover plants
d. approximately 18,000 clover plants
e. none, hawks do not eat clover plants.
11) the microspore develops into a
a. megasporocyte.
b. female gametophyte.
c. microsporocyte.
d. male gametophyte.
e. zygote.
12) transgenic _______ have been given suicide genes that cause them to self-destruct
when the job for which they are engineered has been accomplished.
a. animals
b. bacteria
c. plants
d. fungi
e. all of the choices are correct.
13) which statement is not true of the epidermis of a plant?
a. the epidermis covers the entire body of a herbaceous plant.
b. guard cells are specialized epidermal cells found on root surfaces.
c. the epidermis is impervious to gas exchange.
d. root hairs increase the surface area of epidermal cells on roots.
e. cork cells replace epidermal cells on older woody plants.
14) nitrogen is an essential nutrient for optimal plant growth because it is used to build
a. nucleic acids.
b. protein.
c. chlorophyll.
d. all of the above are correct.
e. nucleic acids and proteins but not chlorophyll.
15) a polypeptide has an amino acid sequence of:
this chain of amino acids is further organized into a helix that in-turn, folds in and
around itself to form a globular structure. the primary structure of this polypeptide is:
a. globular
b. pleated-sheet
c. alpha helix
d. alanine-leucine-tryptophane-glycien-valine-alanine
16) because most roots need gaseous oxygen as well as liquid water, the best soil for
agricultural plants is
a. sand, since it has the greatest pore spaces.
b. clay, since it holds onto water better than silt or sand.
c. silt, because it is intermediate between sand and clay in size.
d. loam, which is a mixture of all size soil particles, and therefore is able to hold water
but drain well.
e. all sizes of soil particles (sand, silt, clay) are equal in soil properties.
