Curare is a poisonous plant extract. Curare molecules have a chemical structure like the neurotransmitter acetylcholine. Curare can bind to the acetylcholine receptor site on the chemically gated ion channels in the motor end plate. Even though curare will bind to the receptor site it will not open the ion channel and no ions will pass through. What do you think the symptoms of curare poisoning would look like?

Bimpnottin the astronaut enters an orbit around a foreign planet of mass 4.50 

Unvera is operating an apparatus containing a flywheel, which accelerates from rest to its maximum angular speed of 25 rpm, turning through 55 revolutions in the process. How long does Unvera’s flywheel take to accelerate to its maximum speed?

POC 17 – PP The nurse is caring for a client that delivered a 9lb -10 oz healthy baby girl two hours ago following a normal spontaneous precipitous vaginal delivery with a 2nd degree laceration.  The EBL was approximately 750mL.  The nurse notes on assessment: VS: HR 106, RR 26, BP 90/50, Temp 99.9, skin is cool and clammy to touch.  Which action is the highest priority in the care of this client?   

Ellywick decides to try to move through a forest by brachiation, swinging below a handhold to move forward to the next handhold. Weighing a petite 40 kg, Ellywick has an arm length (hand to shoulder) of 0.60 m. We can model her motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. At the lowest point of her swing, Ellywick is moving at 2.9 m/s. What upward force must a branch provide to support the swinging Ellywick? 

All epithelial sheets are supported by connective tissue, and its membrane resists stretching and tearing.

Dalaba swings a small block of mass M = 6.0 kg in a horizontal, circular path on a frictionless surface from a spring. One end of the spring is fixed to the center of the circle and the other end is fastened to the block. The relaxed length of the spring is 25 cm, which then stretches to a total length of R = 30 cm during the circular motion. If Dalaba measures an angular speed of 3.5 rad/s, what is the spring constant for the spring k?

The coordination between Mexico and foreign embassies associated with Europe and North America to establish Mexico as a travel destination is an example of international public relations.
