which biological factor is not known to contribute to aggressive behavior? a. temperament b. circadian rhythms c. neurotransmitters d. hormones

The correct answer is option b, that is, circadian rhythms.  

A roughly 24-hour cycle in the physiological procedures of living beings, comprising animals, plants, fungi, and cyanobacteria is known as a circadian rhythm. In a strict sense, circadian rhythms are produced endogenously, however, they can be modulated by external cues like temperature and sunlight.  

The circadian rhythms can affect the release of the hormone, sleep-wake cycles, digestion and eating habits, the temperature of the body, and other essential functions of the body.  

the answer is g1

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.
