Unit1. The organization of the human body

mucosae cells
Hi everyone, we are going to share this small web space, this blog will help you (to study, to enjoy and and to learn more). We have to use english at the classroom, it is hard, but we shall be proud at the end of the Year, I am sure.
Try to focus on words in black and blue at the book, repeat, write and try to understand them.
You should practice doing activities and work on Biology at least twice a week.
Exercise 9 at page 11 mention protozoan, they are very small living thing made of just one cell, at the microscope they can be seen as here.  An answer of this exercise can be as follows: "the survival of cells depend on nutrients and oxygen, our cells get nutrients and oxygen from blood and so they can not live separately from the blood. Nevertheless protozoan, as unicellular, get nutrients and oxygen by themselves, from water and surroundings, they can survive just with water and decay".
Revision activities are about stem cells. they are going to be quite familiar to all of you since stem cells will be used in medicine in 20 or 30 years, to recover from some skinesses. Thus lets to learn about stem cells on page 15, read and answer all questions. To those who want to know more about these stem cells try here.
Who have received the Nobel Prize in Medicine 2012? It was awarded to Sir John B. Gurdon and Shinya Yamanaka for their discovery that "mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Does it sound like stem cells?.
Some videos:  Parts os an animal cell,  A cell rap (funny),  The inner life of the cell (animation)
Higher level, quite useful with transcript, very well explained (much better than mine!) Atour of the cell
