1. Which of the following events is not a source of genetic variation in eukaryotic organisms? J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation

2. Which statement best describes the process of endocytosis?

J. A vesicle within a cell fuses with the plasma membrane and releases its contents to the outside
K. Solid particles or liquid are taken up by a cell through invagination of the plasma membrane
L. Investment in one cytosis reduces the ability of the parent to assist another cytosis
M. One region of an embryo directs the development of neighbouring region of an embryo through movement of cells

3. In eukaryotic cells the conversion of ADP and phosphate into ATP occurs (KA1)

J. only in the mitochondria, and requires energy.
K. only in the cytoplasm, and releases energy.
L. in both the mitochondria and the cytoplasm, and requires energy.
M. in both the mitochondria and the cytoplasm, and releases energy.

4. One consequence of having small regulated steps in an energy pathway is (KA1)

J. an increase in the activation energy for the pathway.
K. a decrease in the amount of heat lost from the pathway.
L. a decrease in the amount of ATP released from the pathway.
M. an increase in the total energy released from the pathway.

5. Adult stem cells in bone marrow can differentiate into a variety of cell types e. g brain, skin, lungs, heart, liver and muscle.
Stem cells that are transplanted from a healthy donor into a patient (recipient) will divide and differentiate into cells of like form and function to the surrounding cells.
The adult stem cells from the bone marrow of the donor would be genetically identical to the cells of the

J. recipient, and divide by mitosis.
K. donor, and divide by mitosis.
L. recipient, and divide by meiosis.
M. donor, and divide by meiosis.
