After swimming in the ocean for several hours, the swimmers noticed that their fingers appeared to be very wrinkled or shriveled
MatroZZZ [7]
<span>The answer is hypertonic. In osmosis, water molecules move from a hypotonic solution to the hypertonic solution, through a semipermeable membrane. This occurs until both solutions become isotonic relative to each other.  In osmosis, only the movement of water molecules occurs since the ions are large enough to pass through the pores of the semipermeable membrane, in this case, the cell membrane. Due to loss of water in the process of osmosis, the cells in the fingers of the swimmers shrunk hence looked shriveled.</span>

How many daltons is in an ion with 15 protons, 16 neutrons and 17 electrons?
Vera_Pavlovna [14]

A dalton is the same as an atomic mass unit. And an atomic mass unit is approximately the mass of a nucleon (proton or neutron) such that the mass is 1 g/mol. So in this problem you have 15 protons and 16 neutrons, so the number of daltons is 15 + 16 = 31.
