Question

Oxygen reaches the veinless cornea of the eye by diffusing through its tear layer, which is 0.500mm thick. How long does it take the average oxygen molecule to do this?

A) (1.67 X 10⁵ s)
B) (2.50 X 10⁵ s)
C) (5.00 X 10⁵ s)
D) (7.50 X 10⁵ s)

Answer 1

To determine the average time for an oxygen molecule to diffuse through the cornea's tear layer, specific diffusion coefficients and material properties are required, which are not provided in the question.

Step-by-step explanation:

The question delves into how long it takes for an oxygen molecule to diffuse through the tear layer of the cornea, which is a biological process. To answer this question, one would typically need to apply the principles of diffusion rates within biological systems, often requiring knowledge of specific diffusion coefficients and the properties of the materials involved (in this case, oxygen and the tear layer). However, without these specific values or a formula provided to calculate the diffusion time, an exact time for how long it takes an oxygen molecule to travel the specified distance cannot be determined simply from the information given. Therefore, in a real educational setting, additional information or context would be necessary to provide an accurate answer to this question.
