Sienna's instructor tells her to perform an experiment by measuring the temperature of a sample of water every 2 minutes. Sienna wants to show a dramatic change in temperature, so Sienna takes the temperature readings every 5 minutes instead of every 2 minutes but still records her data as if the readings were taken every two minutes. Based on the way Sienna takes the temperature readings, identify a scientific trait that Sienna does not have.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

its temperature is increasing. this causes molecular vibrations to increase.
