Having an extra finger, also known as polydactyly, is relatively rare, and people with polydactyly are unlikely to have children with the trait unless both the mother and father <u><em>both</em></u> have it, making it a recessive trait.
Answer:
Explanation:
If the lipid bilayer is at least 108 times less permeable to K ions than it is to water, then a way that this much needed ions can get into the cell is through ion channels.
Ion channels are memberane proteins that form pores and they also span across the cell membrane allowing ions to pass through these pores. They act as a passage through which charged ions can pass through. There are three main type: voltage-gated, extracellular ligand-gated, and intracellular ligand-gated ion channels.
Vestigial structures<span> are often homologous to </span>structures<span> that are functioning normally in other species</span>
Sympathetic is the answer.
Hope this helps and good luck!
