A large population of cockroaches was sprayed with an insecticide. a few of the cockroaches survived and produced a population o
f cockroaches that was resistant to this spray. what can best be inferred from this example? a. a species will adapt no matter what the environment. b. the environment has no effect on the survival of an organism. c. insecticides cause mutations that are passed on to the next generation d. individuals with favorable variations survive and reproduce.
What can be inferred from this excerpt is : ( D ) Individuals with favorable variations survive and reproduce.
<h3>Effects of genetic variations in species</h3>
When the insecticide was sprayed some of the cockroaches survived and continued reproduction due to their resistance to the spray.Therefore it can inferred that although the cockroaches share the same genetic materials, the variations in individuals within the same specie played a role in the survival of some of the cockroaches.
Hence we can conclude Individuals with favorable variations survive and reproduce.
Magnetic declination, or magnetic variation, is the horizontal plane's angle between magnetic north and true north. This angle varies depending on the position on the Earth's surface and changes over time.
