Q:
Tonicity refers to the concentration of a solution in comparison with a living cell. Match each tonicity with the description of its concentration and effect on a cell. Prompts solute concentration in the environment is too high. This causes water to flow out of the cell, leaving it shriveled. Solute concentration in the environment is too low. This causes water to flow into the cell, where this expansion could potentially cause it to burst. solute concentration within a cell is equal to match its environment. Water flows in and out equally, so the cell remains healthy. Select match

Q:
8. The ABO blood groups in humans are expressed as the \( I^{A} \), \( I^{B} \), and \( i \) alleles. The \( I^{A} \) allele encodes the A blood group antigen, \( I^{B} \) encodes B , and \( i \) encodes O . Both A and B are dominant to O. If a heterozygous blood type A parent \( \left(I^{A}\right) \) and a heterozygous blood type B parent \( \left(I^{B} i\right) \) mate, one quarter of their offspring are expected to have the AB blood type ( \( \left.I^{A} I^{B}\right) \) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: 1. multiple alleles and incomplete dominance 2. codominance and incomplete dominance 9. incomplete dominance only 4. multiple alleles and codominance
