A science class investigated the relationship between the amount of time
zaharov [31]

Answer:

A. Based on our results, students who do 1 hour of chores per night

have grades that are on average 0.2 points higher than students

who do no chores.

Explanation:

In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.

From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.

The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

What will the overall charge of an atom be if it has more protons than electrons?
sineoko [7]

Answer:

D

Explanation:

A: Neutrally charged atoms have the same number of protons and electrons.

B: Negatively charged atoms have more electrons than protons. These are also called anions.

C: ironically charged is a molecule that has a charge so a cation or an anion. This option isn't correct becuase it's not specific enough for the question. An ion can be positively charged (cation) or negatively charged (anion).
