Answer:
Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”
Explanation:
Rock candy is a type of candy made by growing sugar crystals on a string or stick.
Why are Super saturated solutions used?Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.
The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.
This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.
As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.
The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.
Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.

Humans benefit from natural resources every day. For example, right now you're using a computer or similar device
to read this question. Can you name any natural resources that were likely used to build this device? What natural
resources are you using by operating it?
Answer:
copper
Explanation:
is a mineral used to make electrical conductors because of its durability.
human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
