An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.
<h3>What kind of respirator offers a separate source of clean air?</h3>
For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.
<h3>What 2 categories of respirators exist?</h3>
Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.
<h3>When should you use an air purifying respirator?</h3>
a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%

Answer:
<h2>B
</h2>
Explanation:
1. The nuclear lamina is a network inside the nucleus which maintain the shape of nucleus.
2. It is composed of intermediate filaments and many proteins.
3. It providing mechanical support to the nucleus and play many other rolls in the cell.
4. In a cell if the nuclear lamina fall into disarray, the nucleus is misshapen and all these processes run awry. Such cells in which nuclear lamina is broken, they tend to become senescent in response to internal dysfunction, and cause damage to surrounding tissue.
Aerobic respiration is the process by which cells produce energy with the use of oxygen. In this analysis, we could suggest that compared to those organisms that are 1000m deep, those that are on the surface can produce energy more efficiently. Hence, they can greatly reproduce doubling their size within a small period of time.
The adaptation that best fit for those that are in 1000m deep is anaerobic respiration.
<span>The chance of the individual has the disease is 1/103, which means there is 102/103 chance to be healthy.
The chance of "at </span><span>least one person has the disease" is the opposite of the chance of "everyone healthy".
The chance that all 500 soldiers healthy would be: (102/ 103)^500= </span><span>0.00761155742

The chance of </span>at least one person has the disease would be: 1- (102^500/ 103^500)= <span>0.99238844257 = 99.24%</span>
