Which of the following is not a proposed hypothesis for why primate brains are larger, relative to overall size? Trichromatic vision relies on complex cognitive function, as facilitated by increased surface area of the brain A larger brain facilitates more complex social interaction within large groups Finding and processing fruits uses more cognitive function than relying on a leaf-based diet

Anemia is characterized by low hemoglobin levels or a reduced number of red blood cells (both of which transport oxygen to cells). A common symptom of anemia is tiredness. Please do not copy answers from another website/source. a) Briefly explain what the consequences are of anemia on cellular energy production. b) Suggest at least one other cellular effect of anemia and a brief explanation of this effect.

9:58 ← LTE 43% PHGY 215 Applied Physi... Questions: 1. Using Table 3, which contains the normal intracellular ion concentrations for most cells in the body, calculate the equilibrium potential for each of the four ions for normal intracellular and normal extracellular ion concentrations. Make sure to show your calculations. Repeat these same calculations, only this time utilize the hyperkalemia values from Table 1. Table 3. Intracellular ion concentrations. lon Intracellular concentration (mM) 150 K+ Na* 15 CI Ca2+ 4 .0001 2. Using Table 4, which contains the relative ion permeabilities for neurons and cardiac myocytes at rest, calculate the resting membrane potentials for both neurons and cardiac myocytes. Make sure to include calculations for both hyperkalemia and normal plasma ion concentrations. Table 4. Relative ion permeabilities for neurons and cardiac myocytes. lon K+ Na+ Neuron relative permeability 1 .04 CI- .45 Cardiac myocyte relative permeability 1 0 0 3. Using Table 2,…
