<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
Mitosis, as a cell gives two daughter cells with the number of chromosome in daughter cells remaining same as that of parent, hence also known as equational cell division.
Answer:
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
It is to dilate the pupil, that the reason why mydriatic drops
are given to the patient before examination.
A slit lamp examination includes
viewing the lens and anterior chamber, in bright light the muscle of the iris
contract, reducing the size of the pupil in order to keep more light from going
inside the eye the process is called miosis.
