MCAT QuestionsWhich ideal solution exhibits the greatest osmotic pressure? a. 0.1 M MgCl2 b. 0.2 M NaCl c. 0.2 M CaCl2 d. 0.5 M Glucose C because the solution listed has the greatest concentration of solute particles. CaCl2 dissociates into three ions (van Hoff factor of 3), making the solution listed 0.6 M in solute particles. Glucose has an i of 1. Which event is directly mediated by a ligand-gated ion channel? a. Release of Ca2+ from the sarcoplasmic reticulum of a muscle fiber to ...

A carrier is an individual who has an allele associated with a trait but does not display the trait. They are, however, able to pass on the allele to their offspring. When setting the simulation's conditions as described above, why does it make no difference whether or not you turn on "show carriers"? Settings: Mode of inheritance - Dominant Parental generation - Male - Heterozygous Female - Heterozygous Matings between relatives - disallow Progeny in first generation - 4 Show carri...
