Pesticides and fertilizers can harm public health and the environment. Many of pesticides contain toxic chemicals that can cause negative health effects such as neurological and cancer and reproductive disorders. Also pesticides can migrate into lakes and streams as they are swept away when it rains. On the other hand fertilizers do cause ground water contamination e.g Nitrogen fertilizers break down into nitrates and travel easily through the soil because of their solubility. this makes them stay in ground water for decades the addition of more nitrogen over the years has accumulative effect.
Answer: True
Explanation: Cell sends and receives signals from each other. This allows for our body to function correctly. For example your brain cells sends many signals to the rest of the body.
This simple concept describes the process by which cells exchange toxic gases for life-sustaining gases. It also describes how nerve cells are able to send electrical signals to each other cells. Diffusion tells embryonic cells where to crawl and when they have arrived. Diffusion also makes it possible to reduce the loss of body heat to the surrounding environment.
