Controls and Variables – Read the description for each experiment and answer the questions. Krusty Krabs Breath Mints Mr. Krabs created a secret ingredient for a breath mint that he thinks will "cure" the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties. 1. Which people are in the control group?

The people in group B

Explanation:

The people in group B are those in the control group.

The control group during an experiment is a group of experimental subjects that either do not receive the treatment variable or are given placebo treatment. The control group is usually established to create a standard to which comparisons can be made during the course of investigating the effects of a particular variable.

In the case of Krusty Krabs, the group that was given regular breath mint without the secret ingredient (group B) will provide the basis for comparing with the other group that received the mint with the secret ingredient (A).

Hence, the people in group B served as the control group.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
