AP Biology Concept
Big Idea 4 : Biological systems interact, and these systems and their interactions possess complex properties.
4.B: Competition and cooperation are important aspects of biological systems.(Chapter 4, 6, 22, 23, 42)
4.B.2: Cooperative interactions within organisms promote efficiency in the use of energy and matter.
4.B.3: Interactions between and within populations influence patterns of species distribution and abundance.
-
-
4.C: Naturally occurring diversity among and between components within biological systems affects interactions with the environment.(Chapter 24, 27, 40, 41, 43)
-
-
-
-
4.A: Interactions within biological systems lead to complex properties.(Chapter 2, 5, 31)
-
-
4.A.3: Interactions between external stimuli and regulated gene expression result in specialization of cells, tissues and organs.
4.A.2:The structure and function of sub cellular components, and their interactions, provide essential cellular processes.
4.A.1: The subcomponents of biological molecules and their sequence determine the properties of that molecule.
4.A.6: Interactions among living systems and with their environment result in the movement of matter and energy.
Big Idea 2 : Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.
2.D: Growth and dynamic homeostasis of a biological system are influenced by changes in the system’s environment. (Chapter 29,31,32)
2.D.2: Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation in different environments.
-
2.D.1: All biological systems from cells and organisms to populations, communities and ecosystems are affected by complex biotic and abiotic interactions involving exchange of matter and free energy.
2.D.4: Plants and animals have a variety of chemical defenses against infections that affect dynamic homeostasis.
2.B: Growth, reproduction and dynamic homeostasis require that cells create and maintain internal environments that are different from their external environments. (Chapter 5)
2.B.2: Growth and dynamic homeostasis are maintained by the constant movement of molecules across membranes.
2.B.3: Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.
-
2.E: Many biological processes involved in growth, reproduction and dynamic homeostasis include temporal regulation and coordination. (Chapter 21,31,32)
-
2.E.3:Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection.
2.E.1:Timing and coordination of specific events are necessary for the normal development of an organism, and these events are regulated by a variety of mechanisms.
2.A: Growth, reproduction and maintenance of the organization of living systems require free energy and matter. (Chapter 1,4)
-
2.A.3: Organisms must exchange matter with the environment to grow, reproduce and maintain organization.
-
2.C: Organisms use feedback mechanisms to regulate growth and reproduction, and to maintain dynamic homeostasis. (Chapter 32)
2.C.1: Organisms use feedback mechanisms to maintain their internal environments and respond to external environmental changes.
-
Big Idea 3 : Living systems store, retrieve, transmit and respond to information essential to like processes
3.B: Expression of genetic information
involves cellular and molecular mechanisms.
(Chapter 14, 15)
3.B.1: Gene regulation results in differential gene expression, leading to cell specialization
-
3.C: The processing of genetic information
is imperfect and is a source of genetic variation.
(Chapter 16, 17, 21)
-
3.C.3: Viral replication results in genetic variation, and viral infection can introduce genetic variation into the hosts.
-
3.D:Cells communicate by generating,
transmitting and receiving chemical signals.
(Chapter 15, 37)
3.D.2: Cells communicate with each other through direct contact with other cells or from a distance via chemical signaling.
-
3.D.1: Cell communication processes share common features that re ect a shared evolutionary history.
-
3.A:Heritable information provides for continuity of life (Chapter 3.6, 12, 13)
3.A.1: DNA, and in some cases RNA,
is the primary source of heritable information.
3.A.2: In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.
3.A.3:The chromosomal basis of inheritance provides an understanding of the pattern of passage (transmission) of genes from parent to offspring.
-
3.E:Transmission of information results
in changes within and between biological systems.
(Chapter 32, 38)
-
3.E.2: Animals have nervous systems that detect external and internal signals, transmit and integrate information, and produce responses.
