Cell membrane of a cell is responsible for the substances
that goes in and out of the cell’s cytoplasm and organelles. It is transports
different materials externally to internally and vice-verse. Hence the cell
membrane is like
<span><span>1. </span>The wall,
window and door of a house.</span>
<span><span>2. </span>The
security guard of a certain bank</span>
<span><span>3. </span>Or the
military sector of a country.</span>
Like these three real-life examples, they regulate and
control the flow of certain entities from outside to inside and vice-versa.
Answer:
"All genetically inherited traits are completely independent of lifestyle factors" is not true
Explanation:
Answer:
Cooperating
Explanation:
Cooperation is "the process of working together" so if you and your friends are working together, you are cooperating. Hope this helps! :)
The light of the moon is sunlight hitting its surface and reflecting it onto us. The phases of the moon are caused by its position in relation to the sun and earth. The light is reflected at different angles, so we see 'phases' of the moon.
Answer;
-Dendrites receive chemical signals.
-When more excitatory than inhibitory signals are received, the cell depolarizes.
-An action potential is set off and travels through the cell and down the axon.
-The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.
Explanation;
-The electrical signal that passes along the axon and subsequently causes the release of chemicals from the terminal buttons
. Chemical signals (excitatory and inhibitory signals.
-Positive sodium pours into the breach, Action potential propagates along the axon, after firing returns to its slightly negative resting state.
-An action potential can be generated if the amount of excitatory input can raise the membrane potential to -55 mV. This then floods the cell with sodium ions and raises the membrane potential. When it reaches a certain point (about +30 mV), the sodium ion channels close and the potassium ion channels open. This drops the membrane potential back down.
