Answer:
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. ... Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.
Explanation:
DNA analysis helps scientists classify similar animals by the evidence of relatedness in general the more derived genetic characters to organisms share the more closely repeated they are...In other words “DNA helps scientists by comparing the similarities in each animal/person’s DNA.
the answer is c. hydrogen bonding
Answer:
I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.
Explanation:
The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.
As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.
The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
I think the molecules that will easily <span>dissolve in water based on polarity not on size would be as follows:
</span><span>CH and small 3 with H OH
</span><span>CH and small 2 with H OH
These molecules would indicate they are alcohols which are definitely soluble in water. Hope this helps. Have a nice day.</span>
