Answer:
no
Explanation:
Density (mass / volume) determines whether an object floats or sinks. If the object is less dense than the medium in which it has been submerged, it floats.
Answer: There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.
The energy left at this level is 10% of the energy that primary consumers have.
Hence, Producers will have 475,650 kilocalories
Primary consumers will have 475,65 kilocalories
Secondary consumers will have 4756.5 kilocalories
Element
An element is a pure substance that cannot be broken down into other substances, an element is made up of only one type of atom.
Hope this helps :)
The question is inappropriate which should be as the following:
A.) What is the dilution factor after Step 1? (2 points)
B.) What is the final/total dilution factor at the end of Step 2 from the starting stock?
Answer:
1. Df- 1/4 r 4 fold or 4 times
2. Final dilution factor- 12 times
Explanation:
A serial dilution refers to the reduction in the concentration of the solute in a solution in which the solution is diluted with the same dilution factor.
In the given question,
The dilution factor will be calculated as the following:
The amount of concentrated solution divided by the total volume of solution
The volume of water added- 300 ul
1. The total volume of solution will be- 100+ 300 ul= 400 ul
Df= 100/400
= 1/4 r 4 fold or 4 times
2.The volume of solution added- 100 ul
solution added to- 200ul
The total volume will be- 300 ul
Df- 100/300 or 3 times
Therefore the final dilution factor will be- 4 x 3= 12
