The identity of an element is defined by itsatomic number (Z), the number of protons in the nucleus of an atom of the element. The atomic number is therefore different for each element. The known elements are arranged in order of increasing Z in the periodic table (Figure 1.24 "The Periodic Table Showing the Elements in Order of Increasing "; also see Chapter 32 "Appendix H: Periodic Table of Elements"),. Q: Elements are defined by their atomic number, a number that describes the amount of what in the element? A:
A:
output: protons

Answer the following question given this paragraph: The first monotremes may have evolved about 150 million years ago. Early monotreme fossils have been found in Australia. An example is a genus called Steropodon , shown in Figure below . It may have been the ancestor of the platypus. Early monotremes retained some of the traits of their therapsid ancestors. For example, they laid eggs and had a cloaca. These traits are still found in modern monotremes. Q: The steropodon may have been an ancestor of which animal? A:
****
A: platypus

Answer the following question given this paragraph: Volcanic eruptions can be devastating, particularly to the people who live close to volcanoes. Volcanologists study volcanoes to be able to predict when a volcano will erupt. Many changes happen when a volcano is about to erupt. Q: Who study volcanoes to be able to predict when a volcano will erupt? A:
OPTIONS:
- vocologists
- virologists
- ornithologists
- volcanologists
volcanologists
