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:
The golgi apparatus packages proteins into vesicles inside of the cell before sending them to their destinations. ... The secretory activities of the cell would also cease to occur. Also, if there is no golgi apparatus, the plasma membrane would be affected because it needs to be able to grow larger for cell division.

Answer:
Protein found in antibodies provides the immunity to our body to fight against any foreign antigen.
Explanation:
- Protein is the building block of our body. It forms the body tissue and even acts as a fuel source.
- But protein found in antibodies are slightly different in their function. In antibodies, protein develops the immunity power that shields our body from the external antigens that may cause dysfunction in our body.
- These antibodies drags out any antigens attacking our body systems.
Answer:
The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.
Explanation:
Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.
The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).
This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.
- The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
- CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.
Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.

Answer:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. ... It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
