TEKS

(4)  Science concepts. The student knows that cells are the basic structures of all living things with specialized parts that perform specific functions and that viruses are different from cells. The student is expected to:

(A)  compare and contrast prokaryotic and eukaryotic cells;

(C)  compare the structures of viruses to cells, describe viral reproduction, and describe the role of viruses in causing diseases such as human immunodeficiency virus (HIV) and influenza.

(9)  Science concepts. The student knows the significance of various molecules involved in metabolic processes and energy conversions that occur in living organisms. The student is expected to:

(A)  compare the structures and functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids;

(10)  Science concepts. The student knows that biological systems are composed of multiple levels. The student is expected to:

(C)  analyze the levels of organization in biological systems and relate the levels to each other and to the whole system.
