Death Valley holds the record for the hottest place on earth. The hottest air temperature ever recorded in Death Valley was 134°F (57°C) on July 10, 1913. Earlier that year, on January 8, 2013, Death Valley experienced a record low temperature of 15°F (-10°C). Suppose that these two extreme temperatures had occurred on the same day, and the gauge pressure in each of your car’s tires was 2.50 x 105 N/m2 at a temperature of -10.0°C and volume of 56.6L before sunrise. What is their gauge pressure later in the afternoon, when their temperature has reached 57.0°C  and their volume has increased to 57.2L (assume there are no leaks in the tire)?

Describe the difference between arteries and veins in terms of their function.

The structures that insects use for gas exchange are called [drop].

The sounds of the heart beating that you may hear are directly caused by:

There are four chambers of the heart, the 2 atria pump blood into the ventricles and the 2 ventricles pump blood out of the heart.

47). Two people with the same genotype for a condition such as asthma have different phenotypes. This results from what type of inheritance pattern?

16). Sex hormones are produced by gonads.
