So I have a wet roll. I put the wet roll into a plastic bag, and in the plastic bag is a wet paper towel. How long will it take to mold?
Answers
Answer:
2 to 4 days
Explanation:
wet roll of paper towels should get moldy in a couple of days depending on the temperature of the room even in a bag so i suggest you just throw it away. But if you do need it then put it in the fridge because mold hates the cold weather, it thrives in warm weather. If you do that then you should have enough time to use it.

Answers
Answer:
Polycrystalline cells are less expensive to make than single-crystalline modules but are also slightly less efficient than the single-crystalline (12% -15%). Also, it has been found that amorphous silicon cells dominate in warm, sunny conditions due to their lower power-loss temperature coefficient [1]
Explanation:
Polycrystalline cells are less expensive to make than single-crystalline modules but are also slightly less efficient than the single-crystalline (12% -15%).
What is Polycrystalline?Solids called polycrystalline materials are made up of several tiny crystals, or "grains." Grain boundaries divide the grains, which typically have variable crystallographic orientations.
The granules' sizes might range from a few nanometers to many millimeters. Small nuclei with haphazard crystallographic orientations first develop at various locations in the liquid during the solidification of polycrystalline materials.
The atoms in the nearby liquid are absorbed by these nuclei, causing them to develop into larger crystals. The crystals eventually collide with one another to form a granular or polycrystalline structure. A region that has emerged from the nucleus of such a structure with the same crystal orientation is known as a grain.
Therefore, Polycrystalline cells are less expensive to make than single-crystalline modules but are also slightly less efficient than the single-crystalline (12% -15%).

What's a chemical change
Answers
Answer:
the appearance of a new substance,
irreversible change has occurred
the absorption or release of energy.
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science of chemistry.

Nitrogen Fixation: Nitrogen-fixing bacteria are found in the soil or in the root nodules of leguminous plants, and they transform atmospheric nitrogen gas (N2) into a form that may be used. These microorganisms convert nitrogen gas into ammonium (NH4+), which plants may utilise.
Nitrification: Nitrification is a process that further transforms ammonium (NH4+). Ammonium is transformed into nitrite (NO2) by the Nitrosomonas bacteria, and nitrite is then transformed into nitrate (NO3-) by the Nitrobacter bacteria. The main kind of nitrogen that plants may receive from the soil is nitrates.
Assimilation: Through their roots, plants absorb nitrates (NO3-) from the soil. Nitrate is transformed inside of plants into organic substances like proteins and amino acids, which are necessary for cellular growth and development in case of nitrogen.
