308. One of the kingdoms that we have studied in biology class are the Fungi. Perhaps the most familiar member of the Fungi is yeast, which is used in making bread, and for producing wine and beer.

c. All living things have DNA.
d. All living things have chloroplasts.

317. Which one of the following best defines homeostasis as it relates to living cells?

a. tendency to reproduce rapidly
b. tendency to maintain a stable internal environment of pH and temperature
c. tendency to die quickly
d. tendency to grow too fast for the DNA to be able to function properly

318. The "basic unit of organization" of living things is the cell. Many living things are a single cell (unicellular), while others are made up of many cells (multicellular). In either case, the cell chemistry involves large macromolecules containing carbon atoms. Which one of the following is NOT one of these carbon-containing macromolecules?

a. carbohydrates
b. proteins
c. nucleic acids (DNA and RNA)
d. water

319. An organism is eukaryotic, autotrophic, and has a cell wall. Which one of the following is the correct classification?

320. Which of the following are prokaryotes?

a. Animals & Plants

c. Fungi
d. Bacteria (Eubacteria and Archaea)

321. For the purpose of classification, which one of the following starts at very general and moves to very specific?

a. Species - Genus - Family - Order - Class - Phylum - Kingdom
b. Kingdom - Phylum - Class - Order - Family - Genus - Species
c. Order - Kingdom - Species - Class - Phylum - Genus - Family
d. Order - Kingdom - Species - Class - Genus - Phylum - Family

322. The taxon Phylum contains all of the following taxa except ____________.

a. Kingdom
b. Order
c. Genus
d. Species

323. The formal "scientific name" for living things has a first part (the Genus), and a second part (the Species within the Genus). Since the Genus for humans is Homo, and the Species name within Homo for humans is Sapiens, humans are called ____________.

b. artificial selection.
c. mutation.
d. homeostasis.

327. Imagine that you tie someone up to a special chair so they can't move and then apply an electric shock to them at 5 volts, 10 volts, 20 volts, etc., while marking on a graph how loud they scream at each voltage. (Never do this experiment!) You control and vary the applied voltage. Therefore, the voltage is the "independent" variable. The response of the tied-up person to the change in voltage, which is the "loudness of the scream," is the _________ variable.

a. independent
b. dependent
c. fixed
d. all of the above

328. The portion of the Earth, including air, water, and land, in which living things grow, reproduce, and are interconnected is often called the ____________ .

a. adaptation.
b. extinction.
c. mutation.

330. The genotype is the gene combination for a given trait, whereas the phenotype is the physical feature that we actually observe. Therefore, two plants might have the same phenotype (for example, both are tall in appearance), yet still have different genotypes (for example, one tall plant has genotype TT, while the other tall plant has genotype Tt). And we observe a small plant only if the genotype is (tt). In this simple example, we see that __________ .

a. the allele for tallness (T) is recessive.
b. the allele for tallness (T) is dominant.
c. the alleles (T) and (t) are both recessive.
d. the alleles (T) and (t) are both dominant.
