Answer:
Sharing electrons occurs when atoms have a covalent bond. Covalent bonds occur between non-metals and there are two types of covalent bonds: Polar and Nonpolar Covalent bonds. Polar covalent bonds are when there is an unequal sharing of electrons which causes the atom that occupies the electron(s) more to have a slightly negative charge while the atom that occupies the electron(s) less has a slightly positive charge. Nonpolar covalent bonds basically have equal sharing of the electron(s).
Atoms bond because they need to become stable like the noble gases.

True
The The National Wildlife Refuge were started in 1903 when there was need to save brown pelicans. This refuge provides home to more than 700 varieties of birds, more than 1000 species of fish, 250 kinds of reptiles and amphibians. They also provide home to countless number of invertebrates and wildlife. Along with animals the National Wildlife Refuge also provides shelter to a large number of plant species.
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein. In the second step, translation, the mRNA is read by a ribosome. The key to a protein molecule is how the amino acids are linked. The sequence of amino acids in a protein is a type of code that specifies the protein and distinguishes one protein from another. A genetic code in the DNA determines this amino acid code.
