Difference between prokaryotes and eukaryotes?
Accept either:
Eukaryotes have a nucleus, prokaryotes don't.
Eukaryotes have membrane-bound organelles, prokaryotes don't.

Veins carry blood (away from/to) the heart.
Arteries carry blood (away from/to) the heart.
Veins carry blood to the heart.
Arteries carry blood away from the heart.

Difference between RNA and DNA?
DNA has deoxyribose. RNA has ribose.
Other accepted answers:
DNA is in the nucleus, RNA in the cytoplasm (of cell)

What is hyperthermia?
Your body temp is too low. HYPER-thermia
100
This uses a weakened/dead pathogen (or an antigen from said pathogen) to trigger an immune response. Your body makes antibodies and memory cells in response to this pathogen, so it can respond to the real deal without causing severe disease. This is called a _________
vaccine

-phile = "to love"
Alkaphiles -- Microorganisms that thrive in pH levels of 9.0 or above
_____philes -- Microorganisms that thrive in pH levels of 3.0 or below
Acidophiles

What is the largest organ in the human body?
Skin

Name the blue organelle.
Golgi Complex, Golgi Apparatus, Golgi Body

Meaning of Acute?
Sudden and Severe

Fill in the blank:
_ _ _ _ _ _ -Cas9 Gene editing (5 letters, acronym)
CRISPR-Cas9 Gene editing
A breakthrough! Bacteria defend against viruses through CRISPR... Cas9 (an endonuclease, sort of like scissors for DNA) slices out segments of viral DNA and insert them into their own genome- called "spacer" sequences. Bacteria use these spacer sequences to help identify invading viruses and destroy them

Billions of years ago, a large host cell engulfed a smaller, primitive photosynthetic bacterium through phagocytosis. Instead of digesting the bacterium, both cells had a mutualistic relationship, where the bacterium would proceed to synthesize sugar in exchange for living inside the host cell. This is called the ________ theory.
Endosymbiotic Theory
300
Where do T cells mature
thymus
300
What do Xylem and Phloem transport through a plant?
Water and nutrients (sugars, amino acids), respectively
300
Meaning of Haemorrhage?
Very Heavy Bleeding
300
What is a plasmid?
Small, circular segment of DNA
400
Name the two prokaryotic domains.
(Hint! There are 3 domains of life: Eukarya, _____, and _____)
Bacteria, Archaea

What is repolarization
When a neuron's membrane potential decreases back down to resting potential
400
What is the name of the bond that joins the DNA/RNA backbone together?
or alternatively:
What is the bond that joins two amino acids together?
Phosphodieter bond
or
Peptide bond
400
The meaning of
tachy- (as in tachycardia)
and
brady- (as in bradycardia)
fast, slow
400
Does DNA move towards the positive or negative end of the well in gel electrophoresis?
Bonus points if you know why
Positive end; phosphodieter backbone has a negative charge, and negative attracts to positive
(For AP Bio kids, this will probably be a question on your Biochem unit 2 test)
500
What is unique to retroviruses?
Reverse Transcriptase-- they carry an RNA genome, and use Reverse Transcriptase to synthesize DNA.

Difference between afferent/efferent neurons
Afferent neurons- carry sensory signals towards the nervous system
Efferent Neurons-- carry motor signals away from the brain, to the muscles
500
What type of chromosomes do mitochondria/chloroplasts have?
(Hint! Our nucleuses contain linear chromosomes. Mitochondria/Chloroplasts, on the other hand...)
Circular Chromosome

What is the common term for "myocardial infarction"?
HEart Attack

What does PCR stand for?
Polymerase Chain Reaction
