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%

The genotype for the possible children is 'AATt, AAtt, Aatt, AaTt'. Woman has normal pigment which means she must have at-least one' 'A. her father is albino and albino allele is recessive , so his genotype is 'aa'. Then 'Aa' genotype is present in skin.
Woman cannot taste PTC because the ability ti taste PTC is dominant .So 'tt' genotype is present for tasting trait. Putting both the trait the woman's genotype is 'Aatt'.
(PTC) Phenylthiocarbamide tasting is a trait governed by pair of alleles , 'T' is for tasting dominant and recessive 't' is for non- tasting.The genotype of parents perform a punnett square to determine the F1 offspring. And the genotype of possible children can be determine.

Reaction will be faster.
Rate of reaction is proportional to the number of enzymes involved in the reaction.
I believe the answer is branch gap sorry if I’m wrong
