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.
Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
Answer:d.Additional evidence will change the theory of evolution into a law.

Answer:
Yes, they are secondary consumers, who sometimes eat phytoplankton
Explanation:
<em>A) near warm water.</em>
<h3><em>
Hurricanes, also called tropical cyclones form in seven distinct basins around the world. Some hurricane formation basins are much more active than others. Some tropical cyclone basins also have conditions in which tropical cyclones may occur over longer periods during the year. Most tropical cyclones form from a disturbance in the monsoon trough. The north Atlantic basin is considerably different, as the majority of hurricanes form from easterly waves originating from Africa. Hurricanes and typhoons only can form over large basins of warm water such as an ocean or gulf. This is due to the fact that they need a large amount of energy which is supplied by the heat from the warm ocean waters evaporating into the atmosphere. Hurricanes also occur at least several degrees away from the equator. This is because the Coriolis force is too weak at the equator to generate spin for the hurricane to develop.
