Answer:
A vacuole is a membrane-bound organelle. They are a kind of vesicle. Vacuoles are closed sacs, made of membranes with inorganic or organic molecules inside, such as enzymes. They have no set shape or size, and the cell can change them as it wants.
Explanation:
Water is predominantly found in cell sap. It serves as a storehouse for the plant cell to act as a storage place for excess nutrients. A vacuole is a membrane-enclosed fluid filled sac.
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%

Its a mutation where you have an extra x chromosome(2 or more x chromosomes in male)
The answer is; TRUE
When the saturated solution is allowed to cool slowly, the molecules in the solution have the time to displace impurities that try to attach to the growing lattice because they fit perfectly, geometrically then the impurities. This way the lattice grows larger.
If the solution is cooled fast, the impurities have little time to be displaced from the lattice hence the geometry of the crystal lattice is disturbed and the crystals are smaller and less pure.
