<span>The correct answer is number one. A chromosome is composed of many genes. A chromosome is referred to as a DNA molecule in an organism's body, which consists of genetic materials. Chromosomes consists of numerous genes within them, in their nucleus and mitochondria, genes are found inside the Chromosomes itself.</span>
Answer:
carbon if only one answer allowed, if check multiple, carbon, hydrogen, and oxygen.
Explanation:
The common elemental ingredients are carbon, hydrogen, and oxygen. They all contain the element carbon. They contain simpler units that are linked together making larger molecules.
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.
Answer:
Deletion.
Explanation:
Cystic Fibrosis is caused by a Deletion Mutation in Chromosome 7. It is a recessive disorder that is hereditary.
The correct answers are: groundwater, wetlands, rivers, ponds .
Fresh water includes all water excluding seawater and brackish water. Fresh water is not the same as drinking water.
It is important for many organisms as habitat and living resource, plants and most mammals requires fresh water to live.
