Boyle's law states that the relationship between pressure and volume of a fixed amount of gas at a fixed temperature is inversely proportional. This means that the higher the pressure, the lower the volume, in a proportional relationship. Therefore, of the statements listed, b: 'the temperature and the number of molecules must remain constant for the law to apply' and d: 'a<span>s the pressure of a gas increases, the volume decreases proportionally</span>' are correct.
Answer:
This type of secretion is known as Holocrine. Whereby the entire cell and content is released
Divergent boundaries occur where tectonic plates are moving away from each other. Mid ocean ridges are, as the name suggests on the floor of the ocean. Some divergent boundaries can be found on land. One example is in Iceland where the Mid-Atlantic Ridge surfaces. This region represents the area where the North American Plate is moving away from the Eurasian plate. Another example can be found in Africa along the East African Rift Valley.
