Answer: 3
NH(3) the three is the number of atoms
Answer:
Mice are breeding machines. They have a gestating period of 19 to 21 days. A female mouse gets pregnant about 5 to 10 times each year and can give birth to a litter of 3 to 15 pups. On average, a female mouse atleast give birth to 35 to 56 pups. The mice reproduce each year, and the mother can mate immediately after giving birth.

C.Normal
Answer:The starch polymer remains unchanged after dissolving in water, but some of the starch polymers dissolve while others hydrolyze into glucose monomers, influenced by temperature and pH.
Explanation:
When starch is dissolved in a solution, it undergoes hydrolysis facilitated by the enzyme amylase to break down into maltose units. The solute concentration of the solution increases and the presence of starch can be tested for with an iodine solution.
When starch, which is a polymer of glucose, is dissolved in a solution, it breaks down into smaller units called maltose due to the hydrolysis reaction. The process is usually facilitated by an enzyme, such as amylase, which facilitates the reaction by providing an alternative reaction pathway with lower activation energy. The liberation of glucose molecules in the solution increases the solute concentration of the solution and can be easily tested for with iodine solution, which would turn from yellow-brown to blue-black upon detection of starch.

Answer:
floor tiles is dependent
wax is the independent
Explanation:
floor tiles needs to depend on the wax to not get scratches
wax does not need to depend on anything
The type of floor wax (Tough Stuff or Steel Seal) is the independent variable, being manipulated for the experiment, while the level of protection against scratches is the dependent variable, being measured and compared.
In this experiment, the independent variable is the type of floor wax being used (either Tough Stuff or Steel Seal), as this is the factor that is being systematically manipulated to determine its effect on the outcome. The dependent variable is the level of protection the floor tiles have against scratches, which is what is being measured and compared between the different wax types.
The independent variable in this experiment is the type of floor wax being tested, with the two options being the more expensive Tough Stuff floor wax and the cheaper Steel Seal floor wax. The dependent variable is the level of protection provided by the floor wax against scratches on the floor tiles.
