Answer: The temperatures on the moon can reach 100 degrees during the daytime, and at night it can get as cold as -173 degrees
Explanation:
Antibodies are released into the bloodstream and attached themselves to foreign antigens such as toxins, bacteria and foreign cells. The attachment of an antibody to an antigen marks the pair for destruction.
This helps maintain homeostasis by providing the body protection against disease and infection.
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
density and specific gravity are properties used to help identify minerals. Density is a measure of the mass of a certain volume of the sample. Specific gravity is a unit less measure, and it is the ratio of the mass of a substance to the mass of an equal volume of water. density and specific gravity are properties used to help identify minerals.
