A. Most of the phospholipids of the endomembrane system are synthesized in the mitochondria.
B. The nucleolus functions in the modification and sorting of lipids and proteins.
C. Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by
membranes of the endomembrane system.
D. Ribosomes move lipids and proteins among the different organelles of the endomembrane
system. - (answer)C. Proteins that will be secreted from the cell are likely to be found in closed
spaces bounded by membranes of the endomembrane system.
Transcribed mRNA exits the nucleus through the _____________. - (answer)nuclear pores

The _____________ is responsible for gene expression in eukaryotes. - (answer)nucleus
According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria
originate? - (answer)From engulfed, originally free-living prokaryotes that could detoxify
oxygen.
Which of the following subcellular structures might be found in a prokaryotic cell? -
(answer)ribosomes
Ciliates (such as Paramecium) are single-celled organisms that are covered with cilia. They use
these cilia to propel them through the water in which they live. The components of the
cytoskeleton that allows theses cilia to move are: - (answer)microtubules made of tubulin.
Which of these does NOT provide evidence for the origin of mitochondria and chloroplasts and
prokaryotic endosymbionts? - (answer)All of the above provide evidence that mitochondria and
chloroplasts originated as prokaryotic endosymbionts of eukaryotic cells.
You are studying the effect of a mutation in vacuole formation in a Paramecium, a free living
protist that lives in freshwater. This mutation greatly reduced the ability of the vacuole to
function properly, so it takes much longer to empty. You place the Paramecium in water that has
very few dissolved solutes (it is almost as pure as distilled water). What do you hypothesize will

happen to this Paramecium? - (answer)It will take in too much water and eventually burst and
die.
People with a mutation in the gene encoding the enzyme Hexosaminidase A have the disease
________________. These people suffer from __________________. - (answer)Tay Sachs /
degeneration of the nervous system
What is the immediate reason that many coral reefs are dying? - (answer)Because they are losing
their symbiotic dinoflagellates due to temperature changes or some other influence.
The dinoflagellates, apicomplexans, and ciliates are all considered members of Kingdom
_______ because they all have __________ beneath their plasma membrane. -
(answer)Alveolata, small alveoli cavities
How is giardiasis usually transmitted? - (answer)It enters drinking water via the feces of an
infected individual, and then enters the gut of another host through the mouth.
Why would a public health worker who wanted to control trypanisomiasis contract an
entomologist (a biologist who studies insects)? - (answer)Because tsetse flies are intermediate
hosts of trypanosomes.
