Answer:
1) in some cases, the same weigh boat will be used by all students: This is True, but the weigh boat must be properly labelled with the compound that is intended to be weighed.
2) the empty weigh boat must be tared (set to zero) before adding material.: This is true because to get accurate weight, it is required to tare the empty weigh boat so as to get the weight of the material alone and not factor in the weight of the empty weigh boat.
3) a paper towel should not be used to transfer product out of a weigh boat: This is true because you want to ensure that no impurities is mistakenly added into the material that is being weighed.
4) the balances in the lab can be zeroed out with a weigh boat on the balance: This statement is true because there must be a counter weight to zero an already existing balances.
5) plastic weigh boats can prevent spillage when weighing liquids into a beaker: This is True because the plastic would help to ensure that the liquids is directly poured into the beaker without spillage.

Answer:
The correct answer is: The participants' abilities to solve geometry problems.
Explanation:
Researches contain both dependent and independent variables.
In a research the dependent variable is the variable that the researcher wants to identify if it changes by modifying the independent variables.
Independent variables are multiple factors that if modified they may or may not change the dependent variable.
In this particular case, Dr Martinez wants to prove the effects of diet on mental alertness. He proceeds to instruct the participants to eat breakfast that's either high in carbohydrates or high in protein (Independent variables) and then Dr. Martinez then measures the participants abilities to solve geometry problems (Dependent variable).
In conclusion, the dependent variable in this study is: Participants' abilities to solve geometry problems.
Mary's sense of self or her self-esteem is being reflected in the passage. As a person develops their personality and undergoes socialization, a growing sense of who they are develops. This manifests into a self-esteem--how they feel about their personality and sense of self--which is the ability to understand who you are as a person.
