Strategies Review of Key Quizzes
Quiz_________________?
Are fungi capable of asexual or sexual reproduction? -
Answer✅
BOTH
Quiz_________________?
Are peptide hormones water soluble? -
Answer✅
Yes. They dissolve in the blood. The blood carries them to their target tissue.
Quiz_________________?
Are protists euk or prokaryotes? -
Answer✅
Eukaryotes
Quiz_________________?
1
, Are steroids polar or nonpolar? -
Answer✅
Nonpolar.
Quiz_________________?
Are viruses living organisms? -
Answer✅
No
Quiz_________________?
As a protein is translated, where do they go once they're in the ER lumen? -
Answer✅
Enzymes in the rER attach a small sugar complex that specifies where the protein will go.
Proteins are carried via transport vesicles to the golgi for organizes/modifies/concentrates
proteins.
Quiz_________________?
As you go down and up the loop of henle, describe where it is becomes more concentrated,
and where more dilute. -
Answer✅
As you go down the loop of henle gets more concentrated, but more dilute as you go up
the other side.
The point is to concentrate solute in the medulla, not the filtrate. This prepares the kidney
to produce concentrated urine.
Quiz_________________?
2
, At the time of birth, at what stage are female eggs at? -
Answer✅
Primary oocyte stage
Quiz_________________?
At what point is the most common for regulation of protein production? Why? -
Answer✅
Transcription
Replication occurs less often and doesn't distinguish between genes.
Quiz_________________?
Basophils: What are they, what % of blood are they? Gran or agran? Lifetime? -
Answer✅
Histamine release
<1%
Gran
A few hrs - few days
Quiz_________________?
By the time the filtrate gets to the loop of Henle, what's it like? -
Answer✅
The osmolarity of the filtrate hasn't changed, but the amount of filtrate has been reduced by
80%, and the consistency of the filtrate has changed.
Quiz_________________?
3
, Can viruses have both DNA and RNA? -
Answer✅
No
Quiz_________________?
Define back mutation. -
Answer✅
The reversion of a mutant to the original phenotype.
Quiz_________________?
Define forward mutation. -
Answer✅
Any mutation which changes a formerly functional wild genotype or phenotype to
nonfunctional
Quiz_________________?
Define lysogenic cycle. -
Answer✅
Viral nucleic acids become incorporated into host genome
Viral genes may remain inactive indefinitely
Viral genes incorporated into daughter cells
Can become activated to be lytic as a result of stress that damages DNA
Quiz_________________?
Define lytic cycle. -
