Write your hypothesis for the “Testing Temperature” portion of this experiment. Be sure to include how you think the decreased temperature will affect blood pressure and heart rate, and, why.
Write your hypothesis for the “Testing Body Position” portion of this experiment. Be sure to include how you think blood pressure and heart rate will vary when you sit versus when you stand.
Explain your results in terms of the endocrine system. Indicate how the endocrine system is involved in the physiological response to temperature and body position.

A rocket ship is launched from rest from a space station. Its destinations 1.0 x 10^11 m away. The ship is programmed to accelerate at 7.4 m/s^2 for 12 hours. After 12 hours, the ship will travel at constant velocity until it comes within 1.0 x 10^10 m of its destination. Then, it will fire its retrorockets to land safely.

At 25 C, you conduct a titration of 15.00 mL of a 0.0400 M AgNO3 solution with a 0.0200 M NaI solution within the following cell:
Saturated Calomel Electrode || Titration Solution | Ag (s)
For the cell as written, what is the voltage after the addition of the following volume of NaI solution? The reduction potential for the saturated calomel electrode is E = 0.241 V. The standard reduction potential for the reaction
Ag+ + e- --> Ag(s)
is E0 = 0.79993 V. The solubility constant of AgI is Ksp = 8.3 x 10^-17.
