Final answer:
Skin Cell A is 50 times as long as Skin Cell B.
Step-by-step explanation:
The correct answer is option D.
Skin Cell A is 50 times as long as Skin Cell B.
According to the given information, Skin Cell A has a length of 5 x 10⁻³ cm and Skin Cell B has a length of 1 x 10⁻⁴ cm.
To compare the lengths of the skin cells, we can divide the length of Skin Cell A by the length of Skin Cell B: (5 x 10⁻³ cm) / (1 x 10⁻⁴ cm) = 50.
Therefore, Skin Cell A is 50 times as long as Skin Cell B.
