The vapors of some chemicals used in the chemistry laboratory, especially isocyanates, can react and bond the contact lens to the eye.

(FYI - the family of isocyanates include Superglue..I wouldn't want to have been the person who discovered this unfortunate reaction!)

A major chemical spill occurred five years ago at Bakerâs Beach, the worldâs sole nesting ground for Merrick sea turtles, and pr
AfilCa [17]

Answer:

<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>

Explanation:

Firstly, There was an oil spill five years ago-no eggs hatched.

Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.

The theory is that a period of 5 years is sufficient to assess effect on population.

If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.

It undermines the argument that the oil spills don't impact the public.
