This chapter consists of topics like Structure and Function - All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular) etc.

Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

This chapter consists of topics like Growth and Development of Organisms - Genetic factors as well as local conditions affect the growth of the adult plant. etc.

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

This chapter consists of topics like Adaptation - Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common. Thus, the distribution of traits in a population changes. etc.

Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

This chapter consists of topics like Structure and Function - Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. etc.

Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.

This chapter consists of topics like Ecosystem Dynamics, Functioning, and Resilience - Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. etc.

Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

This chapter consists of topics like Cycle of Matter and Energy Transfer in Ecosystems - Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem. etc.

Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

This chapter consists of topics like Interdependent Relationships in Ecosystems - Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared. etc.

Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

This chapter consists of topics like Organization for Matter and Energy Flow in Organisms - Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. etc.

Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

This chapter consists of topics like Interdependent Relationships in Ecosystems - Organisms, and populations of organisms, are dependent ontheir environmental interactions both with other living things andwith nonliving factors.In any ecosystem, organisms and populations with similarrequirements for food, water, oxygen, or other resources maycompete with each other for limited resources, access to whichconsequently constrains their growth and reproduction. Growth of organisms and population increases are limited by access to resources etc.

Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

This chapter consists of topics like Natural Selection - Natural selection leads to the predominance of certain traits in a population, and the suppression of others. etc.

Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.

This chapter consists of topics like Inheritance of Traits - Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn sffects the traits of the individual. Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. etc.

Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

This chapter consists of topics like Structure and Function - In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions. etc.

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

This chapter consists of topics like Information Processing - Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories. etc.

Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.

This chapter consists of topics like Evidence of Common Ancestry and Diversity - Comparison of the embryological development of different species also reveals similarities that show relationships not evident in the fully-formed anatomy. etc.

Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.

This chapter consists of topics like Evidence of Common6 Ancestry and Diversity - Anatomical similarities and differences between various organisms living today and between them and organisms in the fossil record, enable the reconstruction of evolutionary history and the inference of lines of evolutionary descent. etc.

Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.

This chapter consists of topics like Growth and Development of Organisms - Animals engage in characteristic behaviors that increasethe odds of reproduction. Plants reproduce in a variety of ways, sometimes depending on animal behavior and specialized features for reproduction. etc.

Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

This chapter consists of topics like Evidence of Common Ancestry and Diversity - The collection of fossils and their placement in chronological order (e.g., through the location of the sedimentary layers in which they are found or through radioactive dating) is known as the fossil record. It documents the existence, diversity, extinction, and change of many life forms throughout the history of life on Earth. etc.

Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.

This chapter consists of topics like Organization for Matter and Energy Flow in Organisms - Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy etc.

Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
