ACSBL059
In plants, gases are exchanged via stomata and the plant surface; their movement within the plant by diffusion does not involve the plant transport system

ACSBL121
Innate responses in animals target pathogens, including through the inflammation response, which involves the actions of phagocytes, defensins and the complement system

ACSCH089
Chemical systems may be open or closed and include physical changes and chemical reactions which can result in observable changes to the system

ACSPH073
A mechanical system resonates when it is driven at one of its natural frequencies of oscillation; energy is transferred efficiently into systems under these conditions

ACSBL058
In animals, the transport of materials within the internal environment for exchange with cells is facilitated by the structure and function of the circulatory system at cell and tissue levels (for example, the structure and function of capillaries)

ACSCH091
Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium

ACSPH064
Momentum is a property of moving objects; it is conserved in a closed system and may be transferred from one object to another when a force acts over a time interval

ACSBL123
In vertebrates, immunity may be passive (for example, antibodies gained via the placenta or via antibody serum injection) or active (for example, acquired through actions of the immune system as a result of natural exposure to a pathogen or through the …

ACSPH025
Energy transfers and transformations in mechanical systems (for example, internal and external combustion engines, electric motors) always result in some heat loss to the environment, so that the usable energy is reduced and the system cannot be 100 percent …

ACSBL113
Hormones alter the metabolism of target cells, tissues or organs by increasing or decreasing their activity; in animals, most hormones are produced in endocrine glands as a result of nervous or chemical stimulation, and travel via the circulatory or lymph …

ACSES024
Water’s unique properties, including its boiling point, density in solid and liquid phase, surface tension and its ability to act a solvent, and its abundance at the surface of Earth make it an important component of Earth system processes (for example, …
