The symbol, the atomic mass, the number of protons and electrons
Answer:
The genetic code is stored in the DNA. DNA is a molecule formed by a sugar, deoxyribose, a phosphate group and four combined nitrogen bases: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). A gene is a part of DNA.
Answer 2325 milligrams.
Explanation:The unit is abbreviated as tsp. Convert Milligrams (mg) to Teaspoons (tsp): 1 mg is approximately equal to 0.0002 tsps. One milligram is a relatively small quantity of table sugar A mere one-teaspoon of granulated sugar contains some 2325 milligrams.

Thompson proposed a model (the plum pudding model) whereby the negatively charged corpuscles were distributed in a uniform sea of positive charge. In other words the positive charge was like the pudding and the negative charge were like raisins on the pudding.
Answer: -
A catalyst is a substance that speeds up the chemical reaction. In the first experiment it took 32 minutes for all the magnesium to react.
In the next it took 54 minutes for all the magnesium to react. So the reaction was slower the second time.
Thus a catalyst was not used.
Powdering up the Magnesium would mean increasing the surface area. More the surface area faster the reaction. Since the reaction is slowing down,
Magnesium was not powdered
If the temperature was decreased then kinetic energy would decrease of the reactant molecules and the reaction would slow down due to less number of collisions between reactant moleules.
So the temperature was decreased is a correct option.
