A.  Explain how processes at the cellular level affect the functions and characteristics of an organism.

1.   Recognize that information stored in DNA provides the instructions for assembling protein molecules used by the cells that determine the characteristics of the organism.

2.   Explain why specialized cells/structures are useful to plants and animals (e.g., stoma, phloem, xylem, blood, nerve, muscle, egg and sperm).

3.   Explain that the Sun is essentially the primary source of energy for life. Plants capture energy by absorbing light and using it to form strong (covalent) chemical bonds between the atoms of carbon-containing (organic) molecules.

4.   Explain that carbon-containing molecules can be used to assemble larger molecules with biological activity (including proteins, DNA, sugars and fats). In addition, the energy stored in bonds between the atoms (chemical energy) can be used as sources of energy for life processes.

 

B.   Explain how humans are connected to and impact natural systems.

N/A

 

C.  Explain how the molecular basis of life and the principles of genetics determine inheritance.

5.   Examine the inheritance of traits through one or more genes and how a single gene can influence more than one trait.

6.   Explain how developmental differentiation is regulated through the expression of different genes.

 

D.  Relate how biotic and abiotic global changes have occurred in the past and will continue to do so in the future.

10. Explain additional components of the evolution theory, including genetic drift, immigration, emigration and mutation.

 

E.   Explain the interconnectedness of the components of a natural system.

7.   Relate diversity and adaptation to structures and functions of living organisms at various levels of organization.

8.   Based on the structure and stability of ecosystems and their nonliving components, predict the biotic and abiotic changes in such systems when disturbed (e.g., introduction of non-native species, climate change, etc.).

9.   Explain why and how living systems require a continuous input of energy to maintain their chemical and physical organization. Explain that with death and the cessation of energy input, living systems rapidly disintegrate toward more disorganized states.

 

F.   Explain how human choices today will affect the quality and quantity of life on earth.

N/A

 

G.  Summarize the historical development of scientific theories and ideas within the study of life sciences.

11. Trace the historical development of a biological theory or idea (e.g., genetics, cytology and germ theory).

12. Describe advances in life sciences that have important, long-lasting effects on science and society (e.g., biotechnology).
