Unit 1(EVO)
This is when distantly related species develop similar “solution” to similar “problem”
What is convergent evolution?
It's when organisms live in groups or cluster around limited resource.
What is clumped distribution?
They are substances that cannot be broken down further or transformed chemically
What are elements?
In the action potential, what happens in the Depolarising phase?
Na+enters
Where does the Krebs ' Cycle take place?
The Mitochrondral Matrix
In the late 1800s, Northern Elephant Seals were hunted to near extinction for their blubber, leaving only about 20 individuals. Today, their population has rebounded to over 150,000. However, they all descend from this small group of survivors.
Which nonadaptive evolution mechanism is illustrated in this scenario?
The bottleneck effect
It's an organism’s rank within its community’s feeding hierarchy
What is a trophic level?
It's a component of an element, consisting of protons, neutrons, and electrons
What's an atom?
What is a neuron
What are the fundamental building blocks of the brain and nervous system?
Difference between Aerobic respiration and Anaerobic respiration.
Aerobic requires Oxygen
Anaerobic does not require oxygen.
This is when individuals with intermediate phenotypes are the most “fit”
What is stabilizing selection?
It's when one species benefits and another is unaffected.
What is commensalism?
It forms when a metal atom GIVES electrons to a nonmetal atom, forming a compound
What's an ionic bond?
Why is the Cerebellum important.
it
Processes sensory information
Involved in movement, coordination, and balance
Half of all of your brain’s neurons are in the cerebellum
What is the Uber
What is NADH2
It is a small, circular piece of DNA found in bacteria (and some other organisms) that is separate from their main chromosome
What is a plasmid?
This human activity increases CO2 in the atmosphere.
What is burning fossil fuels?
It's a charged atom formed by gaining or losing electrons
What's an ion?
What are the steps of Synaptic Transmission
1 Action potential arrives at axon terminal
2 Voltage-gated Ca channels open
3 Ca² enters the presynaptic neuron
4 Ca2 signals to neurotransmitter vesicles
5) Vesicles move to the membrane and dock
6 Neurotransmitters released via exocytosis
7Neurotransmitters bind to receptors
8 Signal initiated in postsynaptic cell.
Where does Glycolosis take place.
What is the Cytoplasm
These two scientists came up with the concept of natural selection.
Who are Wallace and Darwin?
Its the total # of individuals/area
What is population density?
It's the unequal sharing of electrons
What is polarity?
What is a neurotransmitter?
A chemical signal released from the axon terminal of a presynaptic neuron that diffuses to the dendrites of a postsynaptic neuron
What is the Aerobic respiration equation.
CH12O Glucose +6O2 Oxygen +6CO₂ Carbon dioxide->6H₂O~38AТР
