Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
Answer:
The only fact that would allow him to know is if either of his maternal grandparents has PKU
Explanation:
The two alleles for a trait are gotten from the two parents. Hence, for someone to have an autosomal trait, one of the alleles must have come from the father and the other from the mother.
For autosomal recessive traits, a carrier or an heterozygous individuals always appear normal. For Peter's mother to be a carrier for PKU, she must have to inherit the allele from either of her parent. <em>The only way for Peter to know if her mother is a carrier is if either of his grandparents is affected for the disorder. That is, either of them have two affected alleles for the trait where it is certain that Peter's mother will inherit one.</em>
