If used with wisdom, the earth has sufficient resources to sustain its human population. True False
romanna [79]
True. If we all work together to conserve our resources, then the earth will be able to sustain its human population. In this century, many people don't really care about conserving resources because they are too careless to think about how much resources we are wasting on a daily basis. If everyone realizes how much resources we are wasting and helps to conserve them, than earth will have sufficient resources to sustain its human population.
hope this helps:)

A lab assistant needs to mix up the following reaction to prepare DNA for an experiment:_________.
lara31 [8.8K]

Answer:

Explanation:

The total solution formed after mixing the components will be

20 μl + 20 μl + 40 μl + 120 μl = 200 μl

The smallest size tube that will hold the entire reaction is:

Firstly convert 200μl to ml

1000 μl = 1 ml

200 μl = X

X = 200 x 1/1000

X = 0.2 ml

The smallest size tube (from the options provided in the question) is 0.25 ml.

The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.

The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
