Answer:
c: cohesion
Explanation:
This cohesive relationship between the systems is known as pulmonary circulation. It helps the circulatory system in pumping the blood from the feet to the heart.
Answer: Cell A does more work than cell B.
Mitochondria is the energy producer organelle of the cell. It produces energy in the form of ATP molecules. It is a membrane bound organelle which is only present in eukaryotic cells not found in prokaryotic cells. Presence of more number of mitochondria in the cell indicates that the energy requirement of the cell is more. This energy is required for cellular metabolism. Therefore, cell with more mitochondria works more than the one with less mitochondria.
<span> The answer is a misense mutation. In this case, the substitution of the tryosine amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution </span><span><span> in the polypeptide chain </span>was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. </span>
Answer:
The correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
Explanation:
The way one could engineer bacterial cells to produce a human protein is by allowing bacteria to taking up the recombinant DNA. This recombinant DNA are inserted in the form of the vectors.
Recombinant DNA technology or RDT allows individual fragments of DNA from any donor human genome to be inserted into vector DNA molecules with the help of the specific restriction enzyme for both vector DNA and donor DNA.
Thus, the correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
B is the answer.
Hope this helps!
