Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit:
Answer:
1.) Single Displacement Reaction
2.) Synthesis Reaction
3.) Single Displacement Reaction
4.) Decomposition Reaction
5.) Double Displacement Reaction
Explanation:
Single Displacement Reaction: a reaction in which an element is swapped out for another in a molecule
Double Displacement Reaction: a reaction in which the cation of one molecule is swapped out with the cation of another
Decomposition Reaction: a reaction in which a molecule breaks down into smaller molecules/atoms
Synthesis Reaction: a reaction in which atoms or molecules come together to create a larger molecule

This question is incomplete and unclear; the complete question including the missing part is:
Emelie is working on a science project. Her task is to answer the question:
"Does Rogooti (a hair cream sold on TV) affect the speed of hair growth
(in length)". Her family is willing to volunteer for the experiment. Identify the control group (CG) and the independent and dependent variables.
ANSWER:
Independent variable: Rogooti hair cream
Dependent variable: Speed of hair growth/length
Control group: Family members that do not use the Rogooti hair cream
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this case, the ROGOOTI HAIR CREAM is the independent variable.
Dependent variable refers to the variable that is measured or the variable that responds to the change made to the independent variable. In this case, the dependent variable is SPEED AT WHICH HAIR GROWS (IN LENGTH).
Control group in an experiment is the group that does not receive the experimental treatment. In this case, the experimental treatment is the Rogooti hair cream, hence, the control group will be the VOLUNTEER FAMILY MEMBERS THAT DOES NOT RECEIVE THE ROGOOTI HAIR CREAM ON THEIR HAIR.
