(TCO 1) Which of the following diseases or disorders does not support the germ theory of disease? (Points : 4) Anthrax Pneumonia Tuberculosis Cholera Diabetes Question 2.2. (TCO 1) Practical applications of biochemistry include (Points : 4) crop dusters spraying pesticides over an apple orchard. an asthmatic using an inhaler during an attack. a deep sea diver using an oxygen tank while diving. a physician prescribing an aspirin regimen. A, B, and D Question 3.3. (TCO 2) What is the focal point of a convex lens? (Points : 4) The point where the size of a specimen is enlarged. The point where light traveling from a specimen hits the convex lens. The point where refraction (bending of light) occurs. The point where light from the lens is focused. The point where light traveling from a specimen hits the objective lens. (TCO 3) Which of the following statements about parasitic particles is true? (Points : 4) Viroids can infect plants and fungi. Viroids lack nucleic acid. Prions replicate themselves by using the DNA polymerase of the host cell. Prions can be destroyed by cooking meat to an internal temperature of 160° F. Prion diseases involve neurological symptoms. 11. (TCO 4) DNA replication is referred to as semiconservative. This means that (Points : 4) each daughter DNA molecule is composed of one original strand and one new strand. nucleotides are constantly being recycled as cells make DNA. the cell can proofread its newly synthesized DNA only part of the time. the sequence of a DNA molecule is preserved as it is being replicated. each strand of a double-stranded DNA molecule is replicated differently. 13. (TCO 4) Which of the following statements best describes the bacterial chromosome? (Points : 4) It is usually circular. It is found in a nucleoid. It is found in a nucleus. It is both circular and found in a nucleoid. It is both circular and found in a nucleus. Question 14.14. (TCO 5) Which of the following types of bacteria would be most likely to contaminate sauerkraut? (Points : 4) A neutrophile A thermophile An acidophile An obligate anaerobe A mesophile Question 15.15. (TCO 5) Organisms living near the Old Faithful geyser in Yellowstone are classified as (Points : 4) thermoduric. thermophiles. mesophiles. hyperthermophiles. psychrophiles.
Explanation / Answer
1)
Which of the following diseases or disorders does not support the germ theory of disease?
Diabetes.
(germ theory of disease states that some diseases are caused by microorganisms.Anthrax Pneumonia Tuberculosis Cholera are caused by micro-organisms whereas diabetes is inherent propert of cell displaying metabolic disorder)
2.
Practical applications of biochemistry include
a physician prescribing an aspirin regimen.
3.
What is the focal point of a convex lens?
The point where refraction (bending of light) occurs
4.
Which of the following statements about parasitic particles is true?
Prion diseases involve neurological symptoms.
(prions are infectious protein particles. Prions are notable because they can replicate directly as proteins, without making use of genetic information encoded within nucleic acid; )
5.
DNA replication is referred to as semiconservative. This means that
each daughter DNA molecule is composed of one original strand and one new strand.
6.
Which of the following statements best describes the bacterial chromosome?
It is usually circular.
It is found in a nucleoid.
It is both circular and found in a nucleoid.
7.
Which of the following types of bacteria would be most likely to contaminate sauerkraut?
An acidophile
(Sauerkraut is made by a process of pickling called lactic acid fermentation that is analogous to how traditional (not heat-treated) pickled cucumbers and kimchi are made.)
8.
Organisms living near the Old Faithful geyser in Yellowstone are classified as
hyperthermophiles
(A hyperthermophile is an organism that thrives in extremely hot environments— from 60 °C (140 °F) upwards.Temperature measurements of 244 °F (118 °C) have been measured near the Old Faithful geyser in Yellowstone)
