density and specific gravity are properties used to help identify minerals. Density is a measure of the mass of a certain volume of the sample. Specific gravity is a unit less measure, and it is the ratio of the mass of a substance to the mass of an equal volume of water. density and specific gravity are properties used to help identify minerals.

<span>The third option:</span><span>This statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.</span><span>
</span>I mean if you look at rRNA which is needed to make polypeptide chains, it is 2/3 protein, and then the helices, ss binding proteins, DNA polymerase and everything in transcription is protein.
So that last option/ third option is the best
Answer:
B
Explanation:
B is the most likely consequence because of the following facts we are told:
- After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
- Adult apple maggots will only mate on the type of tree on which they were born.
This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).
These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.

Answer:
are
Explanation:
In a heterogenous mixture, it is easy to tell the different pieces and parts from each other. For example, cereal with fruit added to it, or trail mix made of peanuts, raisins and candy. You can easily see the parts of the mixture. A homogenous mixture is one in which you can't see the parts easily, like ketchup or the air we breathe.
