noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.

How does the size of the soil particles impact<br> the soil's permeability (movement of water)?

Usimov [2.4K]

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

there is no cure for Alzheimer's disease or a way to stop or slow its progression, there are drug and non-drug options that may help treat symptoms.

Cause:

Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells.

I chosed it because it is very common
