Air quality also proves to be terrible. there was lack of fresh running water. Tenements housed more than one family in the same apartment. Unsanitary conditions always prevail which is not good for health. These were the housing facilities offered to immigrants until the implementation of new deal Programs.
Answer:
C) Some individual insects are more likely than others to survive and reproduce due to their inherited traits.
Explanation:
Insects are known for their ability to develop resistance to insecticides. Currently there are insects resistant to every synthetic chemical insecticide used. There are many factors to developing resistance, for example:
- many insects species produce large broods. This increases the probability of mutations and ensures the rapid expansion of resistant populations.
- Insects with shorter life times develop resistance more quickly than others because its genetics make them reproduce much faster.
- insects with limited diets are more likely to evolve resistance, because they are exposed to higher pesticide concentrations and has less opportunity to breed with unexposed populations.
But this kind of phenomenon has not only observed in insects in England, rats in certain areas have evolved resistance that allows them to consume up to five times as much rat poison as normal rats without dying.
