Question

1-Whereas spontaneous generation _________________, biogenesis
_______________.
a. was supported by the research of Louis Pasteur, was supported by the work of
Francesco Redi.
b. was disproved by Antony van Leeuwenhoek in 1673, was not disproved until
the late nineteenth century.
c. is the idea that living organisms can arise from nonliving material, is the idea
that all life arises from other living things of the same kind.
d. A and C
e. B and C

2-Following is an abstract published in Applied Microbiology and Biotechnology in
September of 2010:
Based on the results of laboratory and field experiments, we performed a
comprehensive assessment of the _________________ efficiency of glyphosatecontaminated
soddy-podzol soil. The selected bacterial strains Achromobacter sp. Kg
16 (VKM B-2534D) and Ochrobactrum anthropi GPK 3 (VKM B-2554D) were used
for the aerobic degradation of glyphosate. They demonstrated high viability in soil
with the tenfold higher content of glyphosate than the recommended dose for the single
in situ treatment of weeds. The strains provided a two- to threefold higher rate of
glyphosate degradation as compared to indigenous soil microbial community. Within
1-2 weeks after the strain introduction, the glyphosate content of the treated soil
decreased and integral toxicity and phytotoxicity diminished to values of noncontaminated
soil. The decrease in the glyphosate content restored soil biological
activity, as is evident from a more than twofold increase in the dehydrogenase activity
of indigenous soil microorganisms and their biomass (1.2-fold and 1.6-fold for
saprotrophic bacteria and fungi, respectively). The glyphosate-degrading strains used
in this study are not pathogenic for mammals and do not exhibit integral toxicity and
phytotoxicity. Therefore, these strains are suitable for the efficient, ecologically safe,
and rapid _____________ of glyphosate-contaminated soils.
Which word best fills in the above blanks?
a. gene therapy
b. pathogenesis
c. genetic engineering
d. bioremediation
e. spontaneous generation
