The given question is incomplete as options are not provided, however the options are as follows:
A. a large surface area-to-volume ratio
B. ability to form stacks known as rouleaux
C. a convex shape allowing for more efficient transport of oxygen
D. ability to bend and flex when entering capillaries
Answer:
The correct answer is - option C.
Explanation:
RBC cells are biconcave in the shape it is form shape of dub bell in general. These cells are small, round. The biconcave shape of the blood cells helps in the flow of the blood easily and these cells have no nucleus like other cells to have high amount of hemoglobin that is a pigment that carry oxygen and other gases for easy gaseous exchange.
Due to their flexible biconcave shape they can bend and flex accordingly during entering capillaries. The shape of the RBC helps in making stacks and large surface to area ratio.
Thus, the correct answer is - option C.
<em>B. Nucleus</em>
Explanation:
The nucleus would be classified as the control center for the cell. Only eukaryotic cells will contain a nucleus and they are surrounded by cytoplasm.
In the cell, a nucleus is very important to have. One of the most important jobs of the nucleus is the holding of genetic material. Genetic material can be either RNA or DNA, but in this case it is DNA. The nucleus holds DNA, which is obviously very important as it stores genes and heredity information.
The nucleus controls all of the important functions of a cell.

Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
