Answer:
49.54
Explanation:
Given parameters:
Number of organisms in original habitat = 4695
Number of organism in new habitat = 2326
Solution:
To find the percentage of the organisms in the new habitat that has migrated to the new habitat, we use the expression below:
% of the population in the new habitat = \frac{number of organisms in new habitat}{number of organisms in original habitat} x 100
% of the population in the new habitat = \frac{2326}{4695} x 100 = 49.54%

Form of chemicals also affects its toxicity. Some chemicals are harmful in one state and beneficial in another state.
