<h3>What are the limitations of respirator?</h3>
Full-face respirators are bulkier than half-masks and are frequently less pleasant to use. Full-face air purifying respirators cannot be utilized for all sorts of air contaminants because the type and capacity of the filters and cartridges used limit their use.
<h3>What is the capacity of SCBA?</h3>
SCBA Cylinders are available in five sizes to accommodate all <em>Self Contained Breathing Apparatus</em> (SCBA) and Emergency Escape Breathing Devices: 2L, 3L, 6.8L, 9L, and 10L. (EEBD).
The SCBA delivers compressed oxygen from the oxygen cylinder to the wearer via cylinder valves, pressure reducers, demand valves, and other components. The absorbing canister absorbs carbon dioxide from exhaled air, and the breathing bag resupplies oxygen.

Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
Answer:
Piaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence. It was originated by the Swiss developmental psychologist Jean Piaget (1896–1980). ... Piaget's theory is mainly known as a developmental stage theory.
Explanation:
Answer:
Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O
Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O
Explanation:
Dehydration
In chemistry, a dehydration reaction is one that involves the loss of water. In organic synthesis, where an acid is often used as a catalyst, there are numerous examples of dehydration reactions: Conversion of alcohols to ethers: 2 R-OH → R-O-R + H2O Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O Conversion of amides to nitriles: RCONH2 → R-CN + H2O
