Medicine

dlinn [17]3 years ago
7 0

Answer:

The correct answer will be option C- increase the surface area.

Explanation:

At the neuromuscular junctions, the axons of the motor-neurons become bulbous at terminals. These bulbous enlargements are known as the synaptic knobs. The synaptic knob is the bulbous enlargements of the axon present at the terminals. These knobs increase the volume of the axon terminals embedded with the ligand-gated channels and accumulation of neurotransmitters in vesicles.

The motor end plate is the region of the muscle fiber which is responsible for initiating the action potential in a muscle. The motor end plate becomes ruffled or shows small folds or clefts to increase the increased surface area for the neurotransmitter to act.

Thus, option C is the correct answer.

If a patient purchases 2 pint bottles of an antacid and takes 2 tablespoonfuls every 6 hours, how many days will the antacid las
Oksi-84 [34.3K]

2 pints are equal to 64 U.S tablespoons so with that in mind we can get our answer.

There is 24 hours in a day and 24 divided by 6 hours means that the patient is taking the antacid 4 times a day.

2 tablespoons multiplied by 4 is equal to 8 tablespoons a day.

8 tablespoons multiplied by 8 days gets us to our magic number of 64 which is equivalent to the amount of 2 pints.

Answer= 8 days

All of the following expressions are equal except _____. 2 ^ -3 8 1/8 2^1/2^4 math
Brilliant_brown [7]

Explanation:

Option 1 is 2^{-3}

Property is : x^{-y}=\dfrac{1}{x^y}

So, 2^{-3}=\dfrac{1}{2^3}=\dfrac{1}{8}

Option 2 is 8\dfrac{1}{8}

We can write it as : 8\dfrac{1}{8}=\dfrac{8(8)+1}{8}=\dfrac{65}{8}

Option 3 is \dfrac{2^1}{2^4}

Property is : \dfrac{x^a}{x^b}=x^{a-b}

So,

\dfrac{2^1}{2^4}=\dfrac{1}{2^3}\\\\=2^{-3}\\\\=\dfrac{1}{8}

It is clear that option a and c are same. But option b is different.
