As you can see in the picture presented below, the three classes of water have distinctive traits.
Pure substances contain only one element, they are not mixtures of different things.
The homogeneous mixtures have multiple elements, but they are so well blended together that you can't easily observe or separate them.
In heterogeneous mixtures, we can easily differentiate between different elements of the mixture.

Athletes and physically active people have increased needs for
STALIN [3.7K]
They have increased need to carbohydrates, protein, water and iron.

Carbohydrates is the primary source for energy and active people apparently need more energy for their daily activities.

Protein helps build muscles, even though they only need a small amount more of protein than normal people, they still require protein for muscle buildings.

Water has to be needed as they may excrete more sweat by active activities in the day time. Water can also help remove waster material from body.

Iron helps the production of hemoglobin, which is in the red blood cells that help transport oxygen. As they exercise more, they need more oxygen supply for respiration, therefore there is a need for iron supply.

Describe the principal and procedure of spiral plating.
Inessa [10]

Answer and Explanation:

Principal of Spiral plating:In the spiral plate technique, a mechanical plater vaccinates the fluid sample on a pivoting plate agar. The volume of fluid sample decline from the inside to the edge of the plate. The microbial concentration is controlled by checking the provinces on a piece of the Petri dish.

A technique, portrayed for deciding the quantity of microorganisms in an solution by the utilization of a machine which stores a known volume of test on a pivoting agar plate in a consistently diminishing sum as an Archimedes spiral.

Materials used: agar plates, dilution blanks, pipettes

Method:

A spiral plater is a gadget that disperses a constantly diminishing volume of fluid over a solitary pivoting agar plate (the apportioning arm moves like a needle on a turntable, just in reverse). The agar is then hatched and checks are made. It can viably convey up to a 105 concentration range on one plate, yet list requires an uncommon tallying lattice. After the example is brooded, distinctive state densities are clear on the outside of the plate. A changed checking matrix is portrayed which relates zone of the plate of volume of test. By checking a proper territory of the plate, the quantity of microscopic organisms in the example is assessed.
