In your own words, discuss Tay Sachs disease. What organelle within the cell is
impacted? What are the symptoms of the disease and why do they occur? -
answer(1)Lysosomes (2) buildup of toxic lipids inside the cell (biomacromolecules)
(3) disability and death, In the genetic disease known as Tay Sachs, one of the
normally present digestive enzymes inside lysosomes is lacking. Thus, a toxic lipid
in the brain cells cannot be broken down. The resulting buildup of lipids in these
cells can cause intellectual disability and death.
You are observing two cells under the microscope. They are the same type of

larger or smaller cell? Explain why. - answerThe smaller cell. Cells need to remain
relatively small because as a cell expands the amount of surface area
