Which of the following describes the action potential?
Which of the following describes the action potential?
- A continuous shift in voltage with no thresholds
- A Sudden reversal of the membrane's voltage (correct)
- A variable response based on incoming stimulation
- Depends solely on the strength of stimulation
What role do ion channels play during the action potential?
What role do ion channels play during the action potential?
- They allow specific ions to enter or leave the neuron. (correct)
- They independently generate action potentials.
- They maintain the resting potential indefinitely.
- They act as a constant source of voltage for the neuron.

Flashcards
Sexual selection in males
Sexual selection in males
Males compete with each other for access to females, often displaying brighter colours to attract them.
Innate human characteristics
Innate human characteristics
Characteristics present at birth or developing quickly in childhood, like reflexes, curiosity, and basic cognitive skills.
Evolutionary basis of mate choice
Evolutionary basis of mate choice
Males compete for access to females, while females select mates based on resources, status, and dominance, due to the limited number of pregnancies.
