Answer: no
Explanation: some of the cells look the same but some don’t and this is basically saying that they are not all the same. There is like 4 different types of cells.
The answer is the 1st statement.
The diastolic pressure refers the two values are recorded during the measurement of blood pressure.It is the number or the bottom number indicates the pressure in the arteries when the heart rests between beats.
Less then 80 are the normal diastolic blood pressure. Prehypertension which is indicaated by the blood pressure between 80 to 90. The first, systolic pressure, which represents the peak arterial pressure during systole. The second, that represent minimum arterial pressure during diastole.
the force the heart exerts on the walls of the arteries in between beats can be easily measured by the diastolic blood pressure .Diastolic blood pressure is mainly determined by the total arterial peripheral resistance which majorly influence Arterial elastance and compliance.

Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the <u>neuromuscular junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u> <u>At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is up to the threshold levels it generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.
