allsm [11]

For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.

There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.

Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.

With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.

The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.

What does 7263×27 equal
dezoksy [38]

Since it is easily calculated using a calculator, I assume you need this done in the head.

Yes, you can do that.

It takes a few words to explain this, but if you understand how this is done, it goes fast.


27=3*9

so 7263*27 = (7263 * 3) * 9

so first multiply 7263 by 3.

72*3=216, 63*3=189

so 3*7263=21789

So far so good.

Now you can multiply anything by nine by subtracting from the right neighbour, starting from the right.

For example, 27*9. the right neighbour of 7 is 0, borrow 1, so 10-7=3

the right neighbour of 2 is 7, but we borrowed 1, so 6. 6-2=4

At the beginning of the number 27, we add a zero which we subtract from the right neighbour 2 to get 2.

So 27*9=243.

Now for 21789, we have successively

(10)-9=1

8-8=0 (9 was borrowed to become 8)

8-7=1

7-1=6

(11)-2=9

and finally

1 -0 = 1 (2 was borrowed to become 1)

So the final answer is 196101

Flura [38]
The correct answer is "headache and confusion".
The human body has several mechanisms of action in order to protect critical organs from excess blood pressure and flow. When these mechanisms are not successful in protecting the capillaries of the brain, the patient could suffer from cerebral edema (swelling of the brain) and papilledema (swelling of the optic nerve). These conditions could cause severe headache, confusion, motor and sensory problems and visual disturbances.

What is a correct interpretation when using calcium imaging to measure olfactory receptor response?
Gekata [30.6K]

Answer:

The more strongly the ORN is activated, the fluorescence decreases.

Explanation:

Olfactory receptors are commonly known as olfactory ordants receptors that are located on the cell membrane of olfactory receptor nerves. They are mainly used for the detection of different types of smell.

Olfactory receptor response is used t measure the functioning of the olfactory receptor.  The fluorescence element labelled with calcium used in this type of fluorescence. The activation of ORN can be measured by the fluorescence activity. The decrease in fluorescence is associated with the increase in the activation of ORN.

Thus, the correct answer is option (b).
