Answer in True or False:
Bacteria are good at adapting.
Genetic mutations can make bacteria stronger and better able to survive.
Mutated bacteria may be resistant to antibiotics.
A stain of antibiotic-resistant bacteria can spread quickly
MRSA is a powerbug and is difficult to treat.
Antibiotics have been overused.
Antibiotics can be found in soap, toothpaste, and energy drinks
Antibiotics are fed to livestock even when the animals aren't sick
Overused antibiotics kill the strongest bacteria.
Washing your hands with soap and water helps maintain good hygiene.
Bacteria can sneak into your body through cuts and scrapes.

prescription isn't finished.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
