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.

2. what is the independent variable?
3. what is the dependent variable?
4. what should mr. krabs' conclusion be?

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
