For GTA Chelsea's last week, GTA Elizabeth is making her a playlist that she can listen to on her drive to Kansas. Many of the songs picked are great headbanging rock songs that the neighboring cars will hear. Consequently, she correctly realizes that Chelsea's cochleaA: will have lots of V-gated Ca+2 channels being openedB: Will have movement of the Ca+2 based stonesC: Both correctD: Neither correct
A: will have lots of v-gated Ca=2 channels being opened
While preparing for the 2020 Phys Phab Olympics somersault competition, Phys Phab Kaitlyn rolled down the hill by her house. Unfortunately, she could never do more than seven somersaults before feeling extremely nauseous. She thinks at least ten somersaults will be needed to win the gold. Consequently, she is now doing research to develop a medicine that will either (blank) the viscosity of the water within her vestibular system or cause her cerebral cortex to respond as if she was(blank).A. Decrease-Buoyant in waterB. Increase-Bouyant in waterC. Decrease- stuck in quicksandD. Increase- Stuck in quicksand.
increase- bouyant in water
In preparing for this exam, Student X hits play to listen to lecture recordings via headphones. Unfortunately, the volume was still set very high so Dr. Bronson was "screaming".
