<span>If I were a scientist examining the DNA sequence of two unknown organisms that I hypothesize share a common ancestor, I would expect to find similar or almost identical DNA sequence between the two organisms.

Answer:
![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
Explanation:
Given
Initial Form: Onyx
Final Form: Rectangular Solid
Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm
Required
Volume of the solid (in cm³)
The volume of a solid is calculated as thus;
![Volume = Length * Width * Height](https://tex.z-dn.net/?f=Volume%20%3D%20Length%20%2A%20Width%20%2A%20Height)
Assume the following;
![Length = 5.10cm\\Width = 5.10cm\\Height = 2.50mm](https://tex.z-dn.net/?f=Length%20%3D%205.10cm%5C%5CWidth%20%3D%205.10cm%5C%5CHeight%20%3D%202.50mm)
The first thing to do is to convert the assumed height from mm to cm
Given that;
![1mm = 0.1cm](https://tex.z-dn.net/?f=1mm%20%3D%200.1cm)
This implies that
![2.50mm = 2.50 * 0.1cm\\2.50mm = 0.25cm](https://tex.z-dn.net/?f=2.50mm%20%3D%202.50%20%2A%200.1cm%5C%5C2.50mm%20%3D%200.25cm)
Hence, the dimension of the solid in cm is:
![Length = 5.10cm\\Width = 5.10cm\\Height = 0.25cm](https://tex.z-dn.net/?f=Length%20%3D%205.10cm%5C%5CWidth%20%3D%205.10cm%5C%5CHeight%20%3D%200.25cm)
The Volume is then calculated as;
![Volume = 5.10cm* 5.10cm * 0.25cm](https://tex.z-dn.net/?f=Volume%20%3D%205.10cm%2A%205.10cm%20%2A%200.25cm)
![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
Hence, the volume of the rectangular solid is ![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
<span> These related to the polarities of the column and of the eluting solvent </span><span>When you run a column are
1) always start with a more non-polar solvent ratio and SLOWLY increase the polarity of the solvent.
1) Columns are generally made with silica which is highly polar, so compounds that are more polar in nature will interact with the silica more than those that are non-polar.
3) The first fractions to come out should be most non-polar, with each fraction collected after that being more and more polar.

Answer:
Two plates pull towards each other
Explanation:
Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.
This results in different forms of plate interactions depending on the plate types.
- At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere.
- At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain.
- The subduction produces trenches and some volcanic islands.
This is a "Exothermic Reaction."
I did the same test and this was the correct answer.
I hope this helps!
