What are the 20 amino acids? Correct Answer: Alanine. Arginine. Asparagine. Aspartic Acid. Cysteine. Glutamic Acid. Glutamine. Glycine. Histidine. Isoleucine. Leucine. Lysine. Methionine. Phenylalanine. Proline. Serine. Threonine. Tryptophan. Tyrosine. Valine. describe Heisenberg's uncertainty principle Correct Answer: ΔxΔp≥h/4π. "Δx" is the uncertainty in position. "Δp" is the uncertainty of momentum. "h" is the Planck's constant, equal to 6.63E-34 J•s. what is the Arrhenius equation? Correct Answer: k=Ae^(-Eₐ/RT). "k" is the rate constant. "A" is the pre-exponential factor, equal to the steric factor multiplied by the collision frequency. "Eₐ" is the activation energy. "R" is the ideal gas constant (8.314 J/K•mol). "T" is the kelvin temperature. What is proprioception? Correct Answer: sense of body position and movement. What are Pacinian corpuscles? Correct Answer: sensory receptors for deep pressure. Essential for proprioception. What are Meissner corpuscles? Correct Answer: sensory receptors for light pressure. What is the capacitance formula for a parallel plate capacitor? Correct Answer: C=ϵ₀A/d. "ϵ₀" is the absolute permittivity of a dielectric material (in Farads/meter); for a vacuum, ϵ₀ equals 1/(4πk), where "k" is a constant value of 8.99E9 Nm²/C². "A" is the surface area of each plate "d" is the distance of plate separati
