Q: The scale that is used to measure the loudness of sound measures their loudness in what? Read this paragraph and choose the correct option from the provided answers: The most common cause of hearing loss is exposure to loud sounds. Loud sounds can damage hair cells inside the ears. Hair cells change sound waves to electrical signals that the brain can interpret as sounds. Louder sounds, which have greater intensity than softer sounds, can damage hair cells more quickly than softer sounds. You can see the relationship between sound intensity, exposure time, and hearing loss in the following Figure below . The intensity of sounds is measured in decibels (dB). Choices: - waves - weight - centimeters - decibels A:
**Answer**
decibels

Q: Human blood has a buffering system to minimize extreme changes in what? Read this paragraph and choose the correct option from the provided answers: Buffers work well only for limited amounts of added strong acid or base. Once either solute is all reacted, the solution is no longer a buffer, and rapid changes in pH may occur. We say that a buffer has a certain capacity. Buffers that have more solute dissolved in them to start with have larger capacities, as might be expected. Human blood has a buffering system to minimize extreme changes in pH. One buffer in blood is based on the presence of HCO3 and H2CO3 [H2CO3 is another way to write CO2(aq)]. With this buffer present, even if some stomach acid were to find its way directly into the bloodstream, the change in the pH of blood would be minimal. Inside many of the body's cells, there is a buffering system based on phosphate ions. Choices: - sodium level - calcium - ions - ph A:
**Answer**
ph

Q: When the hemoglobin loses its oxygen, it changes to what color? Read this paragraph and choose the correct option from the provided answers: The structure of heme (Figure 19.29), the iron-containing complex in hemoglobin, is very similar to that in chlorophyll. In hemoglobin, the red heme complex is bonded to a large protein molecule (globin) by the attachment of the protein to the heme ligand. Oxygen molecules are transported by hemoglobin in the blood by being bound to the iron center. When the hemoglobin loses its oxygen, the color changes to a bluish red. Hemoglobin will only transport oxygen if the iron is Fe2+; oxidation of the iron to Fe3+ prevents oxygen transport. Choices: - purple red - grayish red - light pink - bluish red A:
**Answer**
bluish red
