Cell Size and Scale, an elegant and deceptively simple interactive from the University of Utah's Genetic Science Learning Center, enables you to compare the sizes of various really small things. The interactive is available free on the Internet and works on desktop computers, smart phones, and tablets.
<span>Adrenaline can change many things including increasing blood pressure, heart rate, reflexes, physical and psychological capabilities, and many more. When under stress, adrenaline is released to help the body defend itself from that stress. That's why when children are drowning, for example, those saving them must be extremely careful because a child can due to adrenaline become even stronger than an adult and can accidentaly drown the adult.</span>
George is lifting weights. He starts by doing biceps curls
which involves flexing his
elbows. His elbow is able to bend
because the humero-ulnar joint is a hinge
joint. Sam is doing leg presses, extending his knees as he pushes
against the weights. Meanwhile, Jane is doing "lat pulls" by pulling
downward on a weighted bar. This movement involves adduction of her arms.
Her shoulder joint is a ball-and-socket joint, allowing
a wide range of movements.
