42,52,55,56,57

42) 76

b)70

Explanation:

52) because you don't want to confuse different units. one ex)1cm is 1/ 100 of a meter

55) 1 km=1,000 meters

b) 10 decimterers = 1 meter

56)The SI standard for length is the meter the standard for volume is the cubic decimeter

ex) 1cm³=1mL

57) The two scales are the same. but there are no negative temperatures in Kelvin. 0 Kelvin is the lowest temperature possible.

0 Kelvin= -274.5 Celsius

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
