Question 2(multiple choice worth 4 points)
(01.01 mc)
a student wants to know which part of his local beach contains the most turtle nests during nesting season. he makes a prediction to investigate based on his observations and plans his experiment. he performs the
experiment to collect data once his experiment is completed, he gathers his evidence and analyzes it to form a conclusion
what part of the scientific method is he missing from this investigation?
a. ask a question
b. construct a hypothesis
c. do background research
d. analyze the evidence
me asap

The correct answer will be option-C.

Explanation:

A scientific method is the systematic approach to understand and explain the natural events and phenomenon.

The method begins with making the observations which could lead to the formation of a scientific question. Background research is done based on which a predicted hypothesis is proposed which could be tested through the scientific experiments.

In the given question, student makes an observation on the basis of which he formulate a question. He do not review the background research on the question and directly formulates the hypothesis and follow other steps.

Since his method lacks the background research therefore, option-C is the correct answer.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
