A rock is a complex mixture of compounds, not a pure substance.
The medulla oblongata, specifically the pre-Botzinger complex, is responsible for the secondary control of respiration. This area helps regulate the rhythm and depth of breathing in response to changes in oxygen and carbon dioxide levels in the blood.
The nervous system is responsible for receiving, interpreting, and producing a response to stimuli. It consists of sensory receptors that detect changes in the environment, neurons that transmit signals to the brain, and the brain itself, which processes the information and generates appropriate responses. This complex interaction enables organisms to react to internal and external stimuli effectively.

Major histocompatibility complex proteins that protect cells from invasion
A signal to which an organism responds is called a stimulus. It can be any environmental change or cue that triggers a response or behavior in an organism. This response can range from simple reactions like moving away from a harmful substance to complex behaviors like mating rituals in animals.
Genes within the Major Histocompatibility Complex (MHC) region, such as HLA genes in humans, code for self proteins responsible for presenting antigens to the immune system. These proteins play a crucial role in distinguishing between self and non-self cells and are essential for immune response regulation and self-tolerance.
complex reaction time is a stimulus response
If a substance didn't turn blue or black with iodine, it means that it didn't form any complex with iodine. When iodine forms a complex with the substance, the complex is generally blue in color.
The living substance of the cell is known as protoplasm, which is a complex mixture of proteins, lipids, nucleic acids, and other organic molecules. Protoplasm is essential for carrying out the various functions necessary for the cell's survival and reproduction. It is responsible for processes such as metabolism, growth, and cell division.
Meat is a very complex mixture.
