An investigation was designed to determine the effect of ultraviolet light on mold spore growth. Two groups of mold spores were grown under identical conditions, except one group was exposed only to ultraviolet light, while the other group was grown in total darkness. In this investigation, what would you name the group of mold spores grown without receiving any ultraviolet light?(1) control
(2) hypothesis
(3) dependent variable
(4) limiting factor

Respuesta :

Answer:

Option A, control

Explanation:

A control group in an experiment is a group which is not exposed to the variables used in the experiment so that the experiment group observations can be compared with the observations of control group and a difference in both the group can be established.

Here , mold spores receiving no ultraviolet light will act as a control group which is not exposed to the variable "light i.e ultraviolet light".

hence, option A is correct.
