Who was the marine biologist whose book silent spring spelled out how the insecticide ddt kills birds and other animals and causes sickness among humans, and who launched the modern environmental movement?

Rachel Carson

Explanation:

Rachel Carson was an American marine biologist and author. She wrote the book Silent Spring to make people aware of the effects of pesticides on the environment. Her book was extremely controversial, particularly for the chemical companies. However, as a result of the information contained in the book, the national pesticide policies were changed and DDTs (as well as other pesticides) were banned, thus launching the modern environmental movement.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
