Answer:
B. compound machine
Explanation:
A CD Player would be an example of a compound machine. A compound machine is one which contains several simple machines. Simple machines are the following: Levers, pulleys, screws, and inclined planes.
The correct answer would be D- lunar.
Option D is the only <span>source of energy that in not currently used to produce electricity in our homes. Researchers are creating lunar panels (similar to solar panels) but there are </span>obstacles to large-scale energy production.
The moon can generate electricity, but for now it's just not accessible.
Honey contains spores of the bacterium clostridium botulinum
Answer:
The atoms of each element have a characteristic number of electrons arranged in electron shells. The number of valence electrons determines what types of bonds or ions the atoms may form, so the chemical reactivity of an atom arises from its electron distribution. The properties of compounds emerge from the arrangement of their constituent atoms and of the bonds between them.
Thus, a wide variety of molecules with very different chemical properties can be made from the same basic atoms. Each molecule has a distinctive size, shape, and charge distribution, which determine its highly specific ability to interact with other molecules.
Compounds in chemical wastes may contaminate the environment if their atoms are combined in new arrangements that harm living organisms.
