In a diabetic some glucose is converted to sorbitol, an alcohol that accumulates in the eye and can cause cataracts. Complete th
vredina [299]

Explanation:

Sorbitol (glucitol) is a type of sugar alcohol that human body metabolizes very  slowly.

It can be obtained by the reduction of the glucose in which the aldehyde group is converted to a hydroxyl group.

If too much sorbitol is trapped in the cells of the lens, it can lead to cataracts, retinopathy and peripheral neuropathy.

The open chain structure of sorbitol is shown in the image below.

In a contracted muscle, which of the following extends from ‘Z’ disc to ‘Z’ disc?
erica [24]

Answer:

The correct answer will be option A - A-band.

Explanation:

The sarcomere is the repeating unit of a myofibril which extends between two z-lines. Under a microscope, a sarcomere can be divided into A- band which is composed of thick myosin only and I-band which consists of thin filament that is actin only.

When a muscle contract then actin and myosin comes in overlapping position due to which I-band shortens and between two z-lines and overlapped structure of thin actin filaments over thick myosin filaments (A-band) is seen.  

Therefore, only A-band is seen between two z-lines in a contracted muscle thus, option A is the correct answer.

Describe a method of calculating the flow rate in the normal pump versus the pump with the narrowed vessels you described above.
charle [14.2K]

Answer:

Taking into account that:

The flow velocity u of a fluid is a vector field

u = u (x, t)

What gives the velocity of a Fluid Plot at position x y time t.

q = || u ||

Now if the flow is continuous as it happens in the blood vessels then:

The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.

Explanation:

As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.

So this is where we have to put emphasis on the biophysics branch that explains the following:

The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.

Indeed, according to Bernoulli's principle:

P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2
