B.1.16 Explain how higher levels of organization result from specific complexing and interactions of smaller units and that their maintenance requires a constant input of energy as well as new material.

 

Molecules and Cells

7.4.1Explain that similarities among organisms are found in external & internal anatomical features, including specific characteristics at the cellular level, such as the number of chromosomes. Understand that these similarities are used to classify organisms since they may be used to infer the degree of relatedness among organisms.

7.4.4 Explain that the basic functions of organisms, such as extracting energy from food & getting rid of wastes, are carried out within the cell & understand that the way which cells function is similar in all organisms.

7.4.5 Explain how food provides the fuel & the building material for all organisms.

7.4.6 Describe how plants use the energy from light to make sugars from carbon dioxide & water to produce food that can be used immediately or stored for later use.

7.4.7 Describe how organisms that eat plants break down the plant structures to produce the materials & energy that they need to survive, & in turn, how they are consumed by other organisms.

8.4.5 Explain that energy can be transferred from one form to another in living things.

8.4.6 Describe how animals get their energy from oxidizing their food & releasing some of this energy as heat.

B.1.3 Know and describe that within the cell are specialized parts for the transport of materials, energy capture and release, protein building, waste disposal, information feedback, and movement. In addition to these basic cellular functions common to all cells, understand that most cells in multicellular organisms perform some special functions that others do not.

B.1.4 Understand and describe that the work of the cell is carried out by the many different types of molecules it assembles, such as proteins, lipids, carbohydrates, and nucleic acids.

B.1.6 Show that a living cell is composed mainly of a small number of chemical elements - carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. Recognize that carbon can join to other carbon atoms in chains and rings to form large and complex molecules.

B.1.7 Explain that complex interactions among the different kinds of molecules in the cell cause distinct cycles of activities, such as growth and division. Note that cell behavior can also be affected by molecules from other parts of the organism, such as hormones.

B.1.8 Understand and describe that all growth and development is a consequence of an increase in cell number, cell size, and/or cell products. Explain that cellular differentiation results from gene expression and/or environmental influence. Differentiate between mitosis and meiosis.

Developmental and Organismal Biology

B.1.14 Recognize and explain that communication and/or interaction are required between cells to coordinate their diverse activities.

B.1.15 Understand and explain that, in biological systems, structure and function must be considered together.

B.1.19 Recognize and describe that metabolism consists of the production, modification, transport, and exchange of materials that are required for the maintenance of life.

Genetics

B.1.26 Demonstrate how the genetic information in DNA molecules provides instructions for assembling protein molecules and that this is virtually the same mechanism for all life forms.

Evolution

Ecology

7.4.2 Describe that all organisms, including the human species, are part of & depend on two main interconnected global food webs, the ocean food web & the land food web.

8.4.4 Describe how matter is transferred from one organism to another repeatedly & between organisms & their physical environment.

B.1.37 Explain that the amount of life any environment can support is limited by the available energy, water, oxygen, and minerals, and by the ability of ecosystems to recycle the residue of dead organic materials. Recognize, therefore, that human activities and technology can change the flow and reduce the fertility of the land.

B.1.44 Describe the flow of matter, nutrients, and energy within ecosystems.

B.1.45 Recognize that and describe how the physical or chemical environment may influence the rate, extent, and nature of the way organisms develop within ecosystems.
