A scientist testing the affects of a chemical on apple yield sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent variable in the experiment?
The first orchard
The second orchard
The number of apples
The orchard sprayed with the chemical yields an average of 60 apples per tree, the other orchard yields an average of 40 apples per tree. Based on the data, the scientist would:
a. report his data
b. test the chemical on other plants
c. determine that the chemical increases apple yield
d. determine that the results were inconclusive
The theory could be altered
The theory is accepted, not the evidence
The evidence is wrong
A vote is taken on whether to accept the new evidence
d. None of the above
a. is absolutely certain.
b. is unchangeable.
c. may be revised as new evidence is presented.
d. is a controlled experiment.
d. both RNA & ribosomes
True or False?
True or false?
a. All living things are made of one cell.
b. Cells are the basic units of structure and function in organisms.
c. Most cells arise from existing cells.
d. Cells are nonliving units that make up organisms.

What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
a. alleles of a gene separate from each other during meiosis.
b. different alleles of a gene can never be found in the same organism.
c. each gene of an organism ends up in a different gamete.
d. each gene is found on a different molecule of DNA.
a. Wrinkled, green seeds

The two major ideas that Darwin presented in The Origin of Species were that evolution occurred and that natural selection was its mechanism.True or False?
a. oxygen concentration
b. light intensity
c. carbon dioxide concentration
a. electron transport
b. Krebs cycle
d. Calvin cycle
a. In the light, plants make their own glucose, but in the dark, photosynthesis stops and mitochondria make glucose.
b. If plants cannot produce enough ATP in the process of photosynthesis to meet their energy needs, they can produce it in aerobic respiration.
c. Sugars are produced in chloroplasts. These sugars can be stored and used by the mitochondria to produce ATP.
d. The leaves and sometimes the stems of plants contain chloroplasts, which produce ATP to meet the energy needs of these plant parts. The roots of plants contain mitochondria, which produce ATP.
a. transfer RNA only
b. messenger RNA only
c. ribosomal RNA and transfer RNA only
d. messenger RNA, ribosomal RNA, and transfer RNA
d. nitrogen base
During DNA replication, a complementary strand of DNA is made from each original DNA strand. Thus, if a portion of the original strand is CCTAGCT, then the new strand will be
