Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen98.5 percentis bound to a protein called hemoglobin and carried to the tissues. Hemoglobin Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 39.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red. Q: Most oxygen in blood is bound to a protein called what, and carried to the tissues? A:
A:
output: hemoglobin

Answer the following question given this paragraph: A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body.

OPTIONS:
- peroxidation
- fermentation
- evaporation
- exhalation

Answer: exhalation

Answer the following question given this paragraph: As the name suggests, open-pit mining creates a big pit from which the ore is mined. Figure below shows an open-pit diamond mine in Russia. The size of the pit grows as long as the miners can make a profit. Strip mines are similar to open-pit mines, but the ore is removed in large strips. A quarry is a type of open-pit mine that produces rocks and minerals that are used to make buildings and roads. Q: A quarry, which produces rocks and minerals used to make buildings and roads, is an example of what type of mine? A:
OPTIONS:
- strip mine
- fracking
- gold mine
- open-pit mine
open-pit mine

Answer the following question given this paragraph: Genes play an important role in determining an organism's traits. However, for many traits, phenotype is influenced by the environment as well. For example, skin color is controlled by genes but also influenced by exposure to sunlight. You can see the effect of sunlight on skin in Figure below . Q: Skin color is controlled by genes but also influenced by exposure to what? A:
OPTIONS:
- food
- precipitation
- makeup
- sunlight

Answer:
sunlight
