1. Loriciferans are microscopic multicellular animals that live in various marine sediments. Scientists have discovered genera of Loriciferans in a deep-sea habitat that lacks oxygen. Before this discovery, some prokaryotes and some unicellular eukaryotes were known to inhabit anaerobic environments. Among the newly discovered Loriciferans is Spinoloricus sp. nov., which is pictured below. Scientists determined that organisms of the genus Spinoloricus were eukaryotes and not prokaryotes because Spinoloricus cells have —
a)
Flagella
b)
Hereditary Material
c)
Cell Walls
d)
Nuclear Membranes
8.
1. A pedigree can be used to _____.

determine whether an allele is dominant or recessive
d)
all of the above
9.
What process is used when the transport protein insulin helps glucose enter the cell?
a)
facilitated diffusion
b)
active transport
c)
osmosis
d)
simple diffusion
10.
A Punnett square shows all of the following EXCEPT _____.
a)
all possible results of a genetic cross
b)
the genotypes of the offspring
c)
the alleles in the gametes of each parent
d)
the actual results of a genetic cross
11.
In the translation of mRNA to proteins, the ratio of nucleotide bases to amino acids is approximately-
a)
