Evolution
This theory was disproven by Louis Pasteur's swan neck flask experiment.
What is spontaneous generation?
These blood vessels have the widest lumen and valves.
What are veins?
What are alveoli?
These are the building blocks of DNA and RNA.
What are nucleotides?
This country's national animal is the unicorn.
What is Scotland?
Miller and Urey made these organic molecules in the lab from inorganic molecules using the same conditions of early Earth.
What are amino acids?
This blood vessel carries oxygenated blood from the left ventricle to the rest of the body.
What is the aorta?
These TWO muscles contract during inspiration.
What are the diaphragm and external intercostal muscles?
The Meselson Stahl experiment showed that DNA replication occurs in this way.
What is semi-conservative?
True or False: A lightning bolt is hotter than the sun
True
These two eukaryotic organelles are through to have originated by endosymbiosis.
What are mitochondria and chloroplasts?
This guy did some simple experiments and observations that proposed that arteries and veins were part of a single connected blood network - arteries pumped blood from the heart and veins returned blood to the heart.
Who is William Harvey?
These alveolar cells produce a surfactant that prevents the sides of the alveoli from sticking to each other during expiration.
What are type II pneumocytes?
This enzyme opens up the DNA double helix and catalysts the reaction between the RNA nucleotides during transcription.
What is RNA polymerase?
This animal sleeps 22 hours a day.
What is a koala?
The evolutionary process by which two related populations diverge into separate species.
What is speciation?
What is the sinoatrial node?
This is the volume of air you can breathe in and out in a normal breath?
What is your tidal volume?
This molecule has an anticodon that recognizes the codon on the RNA molecule and brings an amino acid to the ribosome.
What is tRNA?
This person is currently #1 on the Billboard Hot 100 chart for music.
A type of speciation where several new species rapidly diversify from an ancestral source, with each new species utilising a specific unoccupied niche.
What is adaptive radiation?
This is a type of fatty deposit that develops in the arteries and significantly reduces the diameter of the lumen
What is an atheroma?
This protein found in the walls of the alveoli breaks down and reduces the recoil of the alveoli causing the symptoms of emphysema.
What is elastin?
Watson and Crick used these rather than experiments to help figure out the structure of DNA.
What are models?
This is how many IB biology command terms there are.
What is 30?
