Ruby is conducting an investigation. an advantage of her design is that she can use a large range of variables, but a disadvantage is that it she cannot be sure that one variable is the cause of another. what kind of investigation is ruby most likely conducting?

Ruby was conducting a comparative investigation.

Explanation:

There are three types of investigations: comparative, experimental, and descriptive. The comparative investigation involves collecting data (observations or measures) without controlling the independent variables. Therefore, you cannot be sure of the effects of different variables. On the other hand, in experimental investigations, you can be sure about the effects of the different variables by designing an experiment where you controlled them individually and joined. Finally, descriptives investigation, as the name says, consists of describing observations and patterns.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !

c.more precipitation,but only when emission levels.
