 * Robert Hooke.**

__Who was he?__

Robert Hooke was born on the 18th of July, 1635. Robert Hooke was known as the most important scientist of the 17th century. He attended Oxford University, where he studied the theory of cells. Robert Hooke was also a English Psycian, Biologist and an inventor.

__What was he's job?__

During the time of the 17th century, Robert Hooke was invented the compound microscope. A compound microscope was used to his advantage through out his work. This was one of he's most known and popular inventions.

__What did he contribute to the cell theory?__

Robert Hooke placed thin cork slices beneath a compound microscope, looking into the microscope he discovered that "filled with air that air is perfectly enclosed in little boxes". Basically, the cork was filled with air and there were cells that were seperated individually from one another. The cork was made from plant materials. Robert Hooke then discovered that all living organisms (flora and fauna) are made up of cells.

__Why was he's contribution so important?__

Robert Hooke's had a great importance towards the contribution of the cell theory. He proved that all living organisms are made up of cells and discovered that cells are building blocks of all organisms (flora and fauna). This was an important contribution to the cell theory. It helped future scientists have a greater understanding of all living organisms.


 * Robert Brown.**

__Who was he?__

Robert Brown was born on the 21st of December 1773. He attended Edinburgh Universitiy and was a Scottish botanist.

__What was he's job?__

Robert Brown's was a plant geographer and a scottish botanist were he specialised in the study of plants.

__What did he contribute to the cell theory?__

Robert Brown placed drops of water from a pond beneath a microscope and discovered the particles vibrating against each other. This is know as Browian motion. This the lead to Robert Brown discovery the nucleus in plant cells.

__Why was he's contribution so important?__

Robert Brown had a great importance towards the cell theory with his contribution of his discovery of nucleus in plant cells. This contribution gives us a greater understanding of cell theory and can help today's society with plants and the formation of cells.

// 1. What are radioisotopes used for in medicine? //

Radioisotopes are an advantage for doctors and others involved in medicine to view the inside of the human body and observe soft tissues and organs. Radioisotopes carried in the blood to detect clogged arteries or to see if the functioning of the circulatory system is working correctly.

// 2. Provide 3 examples of a radioisotope and list where it is used. //

Stable isotopes Un stable isotopes natural or man made isotopes. Nuclear medicine such as x-rays, MRI scans and radiation or chemo therapy.

// 3. Choose one of your examples and describe the process. //

Chemo therapy. > > > // List the pros and cons of using radioisotopes in medicine. // > > Pros: Kills cells and cell division of some chronic diseases, such as several types of cancer. > One of the best kinds of treatments in medicine, known as the most successful. > Has improved over the years to cure chronic diseases. > > Cons: Kills good cells and cells division in the body. > When cancer patients recieve treatment, they become very ill. > Coming into High levels can cause damage. > > >
 * Chemotherapy enters the bloodstream and damages dividing cells. Cells in the process of dividing are more at risk of being damaged by chemotherapy. Chemotherapy kills the cell by damaging the part of the control centre inside each cell that makes cells divide. Or it may interrupt the chemical processes involved in cell division.
