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.
I dont even know if i did i would help you
Answer:
Time
Explanation:
During photosynthesis availability of sunlight, nutrients and water are essential. Water is split into hydrogen ion and oxygen atoms. The sunlight provides energy that is used to split water molecules. However, time is an independent factor in primary productivity.

Answer:
A. Cadherins in desmosomes would no longer be anchored to intermediate filaments
Explanation:
Cadherins are Ca dependent molecules (proteins) that are involved in cell-cell adhesion (they are type of cell adhesion molecule-CAM). Cadherins are composed of: a small cytoplasmic component, a transmembrane component, and the extra-cellular part.
There are types of cadherins called desmosomal cadherins which are involved in the formation of desmosomes (structure for cell-cell adhesion) and they bind to linker proteins and keratin intermediate filaments.
