Following are the steps to be taken while handling chemicals with precautions:
1. Application of droppers to transfer small amounts of chemicals into another glassware, as it will inhibit the unwanted overflow of the chemical.
2. Check the test tubes for chips before using them, otherwise, it may leak the chemicals within them.
3. Application of tongs to move the hot components as they may even result in extreme burns.

Answer;
-Birth defects
Explanation;
In animals, long-term exposure to DDT can cause death or severe birth defects.
-DDT stands for dichloro-diphenyl-trichloro-ethane. It is an insecticide/pesticide previously used on crops. DDT has an adverse impact on many organisms such as crayfish, fish, shrimp, and other animals such as mammals.
DDT is slightly to moderately acutely toxic to mammals, including people, if eaten.Animals given potentially fatal doses of DDT develop liver lesions and those given DDT over a long period of time develop liver changes. In these animal populations DDT may cause birth and reproductive defects.
Meiosis
Explanation:
The process in maple trees that decreases the chromosome number in the pollen cells from 52 to 26 is called meiosis.
Meiosis is an important cell division process in which diploid cells are turned into their haploid number.
- In meiosis the cells divides into half and produces four daughter cells from the diploid 2n cells.
- The cell divides twice here. It is common in all sexually reproducing cells.
- It also occurs in all single celled organisms that reproduces sexually.
