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
Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.
Answer: the steel wool in the 3.0 M HCl reacts fastest.

Answer:
Promotes and maintains under which nature and humans can co-exist indefinitely
Explanation:
The ability to sustain something is known as <u>sustainability</u>.
ecology defines it as a means of configuring civilization and human activity so that society, its members and its economies are able to meet their needs and express their greatest potential in the present, while preserving biodiversity and natural ecosystems, planning and acting for the ability to maintain these necessary resources for future generations.
It would not be plants, even though it has cell walls. They are not made of chitin. Plants are also not heterotrophic.
Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.
