Answer:
- factories produce toxic chemicals
- Groundwater Contamination
- Illegal Dumping
- Sewerage
- Leaks and Spills
- Industrial Growth
Explanation:
Chemical waste is a waste that is made from harmful chemicals (mostly produced by large factories). Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States.
[ Impact of Chemical Waste on Water Streams. Improperly managed chemical waste may pollute and contaminate water streams. There are many causes of this type of industrial water pollution, which has both serious and negative impacts on aquatic and human life.]
The stages involved in the development of cancer include limited proliferation, uncontrolled growth and metastasis.
<h3>What is cancer?</h3>
Cancer is a multifactorial disease caused by the uncontrolled proliferation of cells in different parts of the body.
During the first stage, cancer cells are contained in specific tissues, but after a certain period, malignant cells can migrate to other regions of the body in a process known as metastasis.
Cancer stages can be classified from stage 0 (initial disease state) to stage 5 (last progression step), which may result very useful to understand not only the pathophysiologic features of the disease but also to examine its evolution in the clinical setting.
In conclusion, the stages involved in the development of cancer include limited proliferation, uncontrolled growth and metastasis.

Wow that's a good one :). Think about it like this. When you put antibiotics in place where bacterias live, probably most of them will die, however there might be "some" who are resistent to the antibiotic by their nature, (mutations etc.) so among the bacterias which were exposed the antibiotics those resistent ones will survive. And bacterias have a system for exchanging DNA to make each other more resistant, its called "conjugation" look it up. By conjugation they give each other genes which will help them survive. So if we summarize, those who are already resistant survive (which is a cause of natural selection in an environment of antibiotics) and help others resistant too.
To the best of my knowledge, there are only two and they would be ribose and deoxyribose
hope this helps if not just let me know
