Prokaryotic and eukaryotic have structures in common such as plasma membrane, ribosomes, DNA, cytoplasm.
The answer that fits the blank provided above is STEROIDS. Steroids are fat-soluble signal molecules. This is one of the derivative compounds of cholesterol along with Vitamin D and bile salts. All steroid hormones are considered as a derivative of cholesterol. The answer for this would be option D.
Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.
Option C
<h3><u>Explanation:</u></h3>
Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.
This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
Out of the following given choices;
<span>A.
</span>The mouse has a completely different DNA sequence
than the other mice.
<span>B.
</span> The
substituted nucleotide has the same directions as the original nucleotide.
<span>C.
</span>Substitutions in the nucleotides of a mouse's
DNA never affect their phenotypes.
<span>D.
</span>DNA sequences don't determine the color of a
mouse's fur.
The answer is B. Most probably, the nucleotide substitution did not translate to a change in the
amino acid sequence in the translated protein. As you may be aware, most amino
acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG.
Therefore, a substitution, that causes a change to either one of the sequences will not
change the amino acid.
