List 3 carcinogens.
pesticides, asbestos, x-rays, viruses, and many chemicals found in tobacco.
200
What is binary fission?
the parent undergoes cell division to produce 2 genetically identical daughter cells or offspring.
300
Can red blood cells divide? why?
No, because they need the space to carry oxygen.
300
What are the small molecules that are the building blocks of protein?
what are amino acids

What is wrong with the insulin in the people with diabetes?
the DNA in the cells that produce insulin have been altered. Which means the cells can not produce insulin from the instructions or the instructions produce insulin molecules that do not work.
