Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.

Answer:
c. because arteries carry high pressure blood from the heart
Explanation:
Arteries carry the oxygenated blood that is pumped directly from the left ventricle of the heart. Since they receive blood from the heart, the blood pressure is higher in arteries than veins. To withstand the higher pressure of blood pumped by heart, arteries have thicker walls than the walls of veins.
Answer:
The correct answer to the question: Which is a product of cell division by mitosis? would be: the generation of two identical daughter cells, each with the information that was duplicated from the parent cell. This process is what enables cell replication and it is also known as the process for cell division.
In contrast, in Meiosis, the steps of replication and division will produce eggs and sperm cells that are capable of generating human reproduction and the formation of a new being.
Explanation:
In mitotic cell division, a parent cell undergoes replication of all of its internal material, a duplication of it, so that when the process of division of the parent cell begins, the resulting two new identical daughter cells, carry the same information as the parent cell. This allows for cell regeneration and it is the process that is most common in all cells of the body, except, sexual cells of the reproductive system: the egg and the sperm.
