Sample Questions for the Biology Written Comprehensive.
Based on the electron configuration of sulfur, we can predict that the molecular formula of the compound will be C. HAS 6. Review the valences of carbon, oxygen, hydrogen, and nitrogen, and then determine which of the following molecules is most likely to exist.
Plant Evolution and Diversity Questions. 1. What structures did early land plants evolve? How did these help them live on land instead of water? 2. Knowing that convergent evolution can cause plants to be similar, what do you predict would have a better chance of becoming invasive in the desert: a plant from Arizona, or a plant from Maine? 3.
Plant cells differentiate to perform different functions and enable the plant to grow. One cell type is present in young stems and petioles and functions to provide flexible support. This cell type is less resistant to bending forces because it lacks a secondary cell wall and the protein lignin, which causes rigidity in other plant cells.

Plant Diversity Paper Plants are extremely diverse multicellular photosynthetic organisms whose evolution can be traced back to one common ancestor. This common ancestor would most likely be some variation of the common day green algae. Even though these green algae are only modicums of modern day plants they still contain the most important.
The hottest spots for species diversity are tropical rainforests. Species diversity is important for ecosystem health and for medicine. If a species disappears, an entire ecosystem can start to.
Hannah Porter Mr. Condo Pre-AP Bio-1 November 4, 2014 Pre-Ap Biology Research Paper The cell is the basic unit of life and is the smallest, simplest organism that can perform all of life’s functions. The cell was discovered in 1665 by Robert Hooke. The three types of cells are plant cells, animal cells, and prokaryotic cells. These cells share many qualities but are also different in many.
