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.

Other than tablet hardness, which method is used to measure the tablet strength?
Anni [7]

There are 2 main processes to test tablet hardness: compression testing and 3 point bend testing. For compression testing, the analyst generally aligns the tablet in a repeatable way, and the tablet is squeezed between a fixed and a moving jaw. The first machines continually applied force with a spring and screw thread until the tablet started to break. When the tablet fractured, the hardness was read with a sliding scale.

kirill [66]

The attenuated oral poliovirus vaccine (OVP) is no longer administered in the U.S.A. because it can be spread to contacts and can occasionally cause poliomyelitis.

<h3>What is Vaccine?</h3>

The vaccine may be defined as any substance which is prepared for the stimulation of antibodies and furnishes immunity against one or several diseases.

Oral poliovirus vaccines have chances to revert back into their wild-type strain and again cause disease. Children vaccinated with oral polio vaccines shed poliovirus which spread to contacts.

Therefore, it is well described above.
