Answer:
The answer is B, control variable; Different groups of cattle are given different doses of antibiotics.
Explanation:
Control variable is a variable that is held constant in order to assess or clarify the relationship between other variables in an experimental design. Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
The concern of the experiment is the relationship between antibiotics and growth rate, hence the animals will be grouped in at least 3 treatment groups and each would be given different level of antibiotics, and a control group which won't be given any antibiotics. Though every other variable like feed, drink, temperature etc will be same for all groups including the control group in order to prevent bias.
At the end of the experiment, the control group which wasn't given any antibiotic will be compared with those groups which were given, hence the group which performs best would be determined.
Answer : There would be one bar shorter than the bar for peaches.
Explanation : According to the given information about the carbohydrates present in same size of servings of 237 Milli Liter of Fruit
in grams, when it is converted into graph then, there would be one bar shorter than the bar of peaches.
As most of them are beyond 16 grams, only one fruit is below 16 grams that is watermelon. Watermelon bar will be only the one which will be shorter than the peaches bar in the graph. Rest all will be higher than the peaches bar on the graph.
