: a type of observation which can be counted or measured, often using tools like a thermometer, a scale, or a ruler. : all the data collected during scientific investigations. It is best gathered by doing the investigation yourself, not reading other peoples’ work. (two words) Scientific : a specific relationship under given conditions that tells what happens in the natural world. Based on a body of evidence, they are universal and will rarely if ever change. Scientific : a well-supported and widely accepted explanation of nature. They can and do change if new evidence arises.

I hope I got these right and I hope you got the help you wanted!

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
