4.05 kg + 567.95 g + 100.1 g add the correct value using the correct sig figs and or least precise degree of precision. when i did least degree of precision i got 4718.1g, do we need to convert the kg unit to grams before getting the least degree of precision? since i used 100.1 as dop and if i had converted first the dop of 4.05 or now 4050g the dop is now only to the tens place compared to being in the tenths place

To find the least degree of precision we swould model it after the kg amount or 4.05 kg or two decimal places. So that would add 0.56795 kg (0.57 kg) and then 0.1001 kg (0.1 kg) so that our answer would be 4.72 kg.

In the other hand, the greatest degree of precision would be to conver 4.05 kg to 4050 g so that 4050g + 567.95 + 100.1 g= 4718.05 grams or 4718 g.

a

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.
