Answer:

The correct answer will be option-D

Explanation:

The biological Edema refers to the swelling of any portion of the body which could be small or large. The swelling is caused when the fluid from the blood vessel is leaked to the nearby tissue which causes the redness also.

Edema is assessed by measuring the depth of the pit formed by swelling in which 4+ edema shows that the edema is very deep pitted (6-8mm) which could last for 2-5 minutes.

Thus, option-D is the correct answer.

What refrigerant safety group classification has the highest flammability and the highest toxicity?
timama [110]

Answer;

-B3

Explanation;

Refrigerants are divided into two groups according to toxicity:

-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or  equal to 400 ppm;  and

-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.

They are also divided into three groups according to flammability:

-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101  kPa;

-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3  at 21°C and  101 kPa and a heat of combustion of less than 19 kJ/kg;

-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less  than or equal to 0.10 kg/m3  at 21°C and 101 kPa or a heat of combustion greater than or equal to 19  kJ/kg.

-Therefore; the answer for the above question would be Class B and class 3.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.
rusak2 [61]

During volume changes in the thoracic cavity, <u>Diaphragm</u> is primarily responsible for changes in length.

The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.

The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.

Thus, diaphragm is responsible for the increase in length of the thoracic cavity.
