Fill in the appropriate word or term for the following statements. a. -150 mV
b. Voltage-gated
c. resting
d. super- depolarization
e. +30 mV
f. +15 mV action
g. action
h. close
i. open
j. hyperpolarization
1. Voltage-gated K -50 mV channels remain open, causing a of the membrane. The membrane is now in its relative refractory period.
2. The membrane is at the potentials occasionally generating graded potential. open
3. Voltage-gated K channelsand the resting potential of the membrane is restored.
4. At about voltage-gated Na* channels are inactivated, and voltage-gated K channels open. Kt exits the cell and repolarizes the membrane. At this time, the membrane is in its absolute refractory period.
close
5. An action potential is triggered when the threshold potential of about is reached. Voltage-gated Na+ channels open. Na* diffuses into the cell and depolarizes the membrane.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
