Following statements are regarding to the regulation of body temperature.
A. The temperature-regulating center is located in the anterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the skin and about core temperature from thermoreceptors in the anterior hypothalamus itself.
B. The temperature-regulating center is located in the posterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the posterior hypothalamus itself and about core temperature from thermoreceptors in the skin.
C. If core temperature is below the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
D. If core temperature is above the set-point temperature, then heat-dissipating mechanisms are activated.
E. If core temperature is below the set-point temperature, then heat-dissipating mechanisms are activated.
F. If core temperature is above the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.

Choose correct statement about Electrocardiogram Augmented Limb Leads.
a. In this type of limb lead system, two of the limbs are connected through the positive terminal of the electrocardiograph, and the third limb is connected to the negative terminal. 
b. In this type of limb lead system, two of the limbs are connected through the negative terminal of the electrocardiograph, and the third limb is connected to the positive terminal. 
c. When the positive terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
d. When the negative terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
