MileDown MCAT Biology Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the role of the myelin sheath in neural transmission? The myelin sheath insulates axons, allowing for faster transmission of electrical impulses along the neuron through saltatory conduction. Describe the process of endocytosis in cellular transport. Endocytosis is a process where the cell membrane engulfs extracellular material, forming a vesicle that brings the material into the ce...

Hemoglobin O₂ binding affinity decreases under what conditions: - Bohr Effect Low pH (High CO₂ and high H⁺)=> oxygen loads released by hemoglobin if do opposite (decrease CO₂ or H⁺)=> increase affinity for oxygen Haldane Effect - if you increase the pressure of CO₂=> increase CO₂ content in blood. * oxygenation of blood in the lungs displaces CO₂ from hemoglobin=> increase CO₂ removal *Hemoglobin without O₂ acts as blood buffer by accepting H⁺... this will...

A summary of haemoglobin, oxygen transport and the BOHR effect as seen on the CCEA spec for AS Biology in Northern Ireland. This is a document showing the most important pieces of information which are crucial when trying to understand this module.

Theorized the concept of stimulated emission - correct answer Einstein Theorized that an excited electron will spontaneously return to its ground state - correct answer Bohr First ruby laser was created in _____ by ______. - correct answer 1960, Ted Maiman _________ reported in 1965 that a ruby laser could vaporize enamel. - correct answer Stern and Sognnaes First pulsed Nd:YAG laser released in ______ and cuts ______ tissue. - correct answer 1990, soft tissue In _____ t...

Introduction to Quantum Mechanics Graded A+ Back to Bohr: Bohr gave us Quantization Quantization means electrons can only exist in certain discrete energy levels (like a staircase, they can only completely be on the first or second stair but never in between stairs different distances from ground) If you recall rings= orbits e- must be in a _______ and e- are different distances(or E) from ________ orbit; nucleus Bohr was Bad: Bohr model of the atom could predict the ____________ _...

Acceleration - Any change in speed or direction Activation energy - the amount of energy needed to start a reaction All objects experience the same acceleration due to - gravity, but only in the absence of air friction Alloys - mixture of metals Alpha decay - a nucleus gives up a helium nucleus Amplitude - The height of the wave, how far you are from the equilibrium Angular Momentum conserved - Angular momentum = Mass * Velocity * Radius Ice Skater ex. As she pulls her arms in, velocity i...
