These fundamental discoveries have a great impact on all aspects of cell growth. Defects in cell cycle control may lead to the type of chromosome alterations seen in cancer cells. This may in the long-term open new possibilities for cancer treatment. 2. Read the FAQ about skin cancer from The Skin Cancer Foundation and the Center for Disease Control and Prevention.

PATTERNS IN NATURE – Summary Notes 1. ORGANISMS ARE MADE OF CELLS THAT HAVE SIMILAR STRUCTURAL CHARACTERISTICS 1.1 Outline the historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown The Cell Theory states that: All living things are made of cells (Theodor Schwann & Matthias Schleiden) Cells are the basic structural and functional unit of organisms (Theodor Schwann) All cells come from pre-existing cells (Rudolf Virchow) The historical

distinguish the living from the nonliving? The characteristics that distinguish the living from the nonliving are that nonliving things reproduce and grow‚ use energy‚ have levels of organization‚ maintain constant internal conditions‚ and evolve. 2. List the levels of life’s organizational hierarchy from smallest to largest‚ starting with atoms and ending with the biosphere.

must grow the correct amount of stoma (for gas exchange/water loss) to the light levels in an area (even if they are shaded) this gives them a balance. Method: 1. Obtain two leaves from a shrub‚ (One from the centre and one from the outer area) 2. Paint a thick patch of clear nail polish on each of the leaves surfaces (lower/upper epidermis) being studied. (Make a patch at least one square centimetre. 3. Allow the nail polish to dry completely on both sides of the leaves. 4. Tape one piece

Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal Compartmentalization- does not have internal compartments and no membrane organelles Flagella- no 9+2 structure

courses. According to the College Board’s website‚ AP Biology courses are designed to be the equivalent of a college introductory course‚ usually taken during a biology major’s first year of college. Students who choose to take AP Biology may be allowed to skip over introductory biology courses and enroll in courses in which biology is a prerequisite. Because universities grant college credit for this course‚ they require that the textbooks‚ labs‚ and coursework used by AP courses be equivalent to

2. The connection between what Wyatt Transgenics Company does‚ and the reference to the comic “The Swamp Thing” is‚ that they both have to deal with organisms that undergo some sort of manipulation. “The Swamp thing is an example of this. (Page 64-65) 3. The meaning of transgenic is when an organism is altered by having a gene from another species transferred into it. (Page 64) 4. The scientists make the animals develop the desired proteins by‚ putting original human genes in to the animals
