It maybe man mater of his destiny i gueesed
I think that it is after the salutation or before the closing of the letter. If it were a letter, it would look like this:
Dear Dr. Doctor,
(Dear is the Salutation). Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter.
Sincerely,
Brainly
The singular is child and the possessive plural is children's
Science helped through making medicine more effective and hospitals have better treatments and high hygienic standards for the patients and work place itself
Science has made businesses become more successful because though science new inventions can be made to make humanity’s life more comfortable like the cell phone, computers and robots
Science has also helped because construction protocols and way of building have changed for the safety and well being of both the construction workers and the people or clients. It also makes things more easy and comfortable.
Hope this helps you dear If you need anything else just ask me
