since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4

Nutka1998 [239]

We have that for the Question "since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that

Why the Kirby bauer test require that the agar have a ph of 7.4 is because while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

From the question we are told

since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4

Generally

Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared

Therefore

Why the Kirby bauer test require that the agar have a ph of 7.4 is because

while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would

Aleksandr [31]

Answer:

Three different kinds of muscles are -:

SKELETAL MUSCELES
CARDIAC MUSCLES
SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.
CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart.
SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.
