Jill is a botanist studying pear production by two different types of trees. type a trees produce 20% more pieces of fruit than type b. If a type a tree produced 144 pears, how many should a type b tree produce based on Jill's findings.
the type a tree produces 20% more than the type b. Given that jill's findings were accurate, you can divide the amount given for the type a tree, 144, by 120%. You can do this because for every 1 pear produced by a type b tree, a type a tree will produce 1.2 pears. So 144/1.2=120 pears.
The pattern observed by the professor may REPEAT ITSELF AGAIN in 2023. make appropiate changes to the capatilized portion a. no change b. repeat itself c. again, repeat itself
the correct choice is b. choices a and c are incorrect because again is superfluous. the word repeat already implies that this would be a reoccurring pattern, rendering the again unneeded.
Scientist 2 explains that ice sublimes to water vapor and enters Europa’s atmosphere. If ultraviolet light then broke those water vapor molecules apart, which of the following gases would one most likely expect to find in Europa’s atmosphere as a result of this process? a. Nitrogen b. Methane c. Chlorine d. Oxygen
this is a question which looks for a sound answering strategy. This question over complicates the concept of evaporation, and it is important for the reader to ignore the over complications. There are only two elements present in water- hydrogen and oxygen. Only one of these is a possible choice, so the correct response is oxygen.
