Hello,
As a matter of fact, sharks have extremely good eyesight. In fact, they can see surprisingly well in dark lighted areas. Did you know that a shark's eyesight is very similar to a human's eyesight?
Sharks are commonly mistreated as the meanest sea creature in the ocean because of their aggressive appearance. In my opinion, I believe the Killer Whale is the ocean's top killer.

Answer:
500 out of every 1000 rats would die
Explanation:
Given LD (Lethal dose) = 50
This is the amount required to kill 50% of a test population
To get the whole test population,
Therefore 50/100= 250
That is 50 to 100
250 to x
Cross multiply
(250 × 100)/50
=500 (that is 50% of the population)
The whole population will be 500 × 2=1000
