Suppose that in a neuron, ena is +58mv: ek is -80mv, and vrest
is+50mv. what can you correctly assume about the
concentrationgradients and permeabilities for na+ and k+ in this
cell? circleall that apply
i) in this neuron, both na+ and k+ are at equilibrium whenthe cell
is at vrest.
ii) in this neuron, the external k+ concentration is greaterthan
the internal k+
concentration.
iii) in this neuron, the membrane is permeable to na + butnot to
k+.
iv) in this neuron, the k+ permeability of the membrane isless than
the na+ permeability.

Dr. kaylan is an ecologist who studies bird behavior. she sets up an experiment to test which type of food crows are most likely to eat when given a choice between walnuts, corn, and sunflower seeds. to perform her experiment, dr. kaylan places three food bins in an area frequented by cows. each bin contains one of the three food types. then, she measures how much of each food type is eaten every day for a month and summarizes the results of her experiment in the pie chart below. based on her results, dr. kaylan concludes that crows choose to eat corn more frequently than other food sources because it has a higher nutritional value. what is a reasonable alternate conclusion that can be drawn from dr. kaylan's data
