bixtya [17]

1. Answer;

1000 times

If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about 1000 times.

Explanation;

If the surface are increases 100 times it means that the side of a cube has increased by a scale factor of 10, therefore, the volume of the cube will increase about 1000 times ( 10 × 10 × 10 = 1000).

2. Answer;

Moving needed materials in and waste products out.

Explanation;

Large cells have more trouble moving materials that are needed in the cell and wastes products out of the cell, as compared to small cells.

The volume of large cells is so large, the surface area, by comparison, is relatively small, thus large cells have a small surface are to volume ratio, compared to small cells which have a large surface area to volume ratio, which makes the transportation of substances into and out of the cells extremely efficient compared to large cell.
