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.
Explanation:
Protein synthesis is a biological process whereby individual cells build their own specific proteins. In the process of protein synthesis, it involves both ribonucleic acid (RNA) and (deoxyribonucleic acid) DNA. This process initiates in cell’s nucleus whereby some specific enzymes unwind the needed part of DNA and makes it accessible and a copy of RNA is made. In transcription DNA double helix which is used as a template is where information of DNA is copied to RNA as one strand.
RNA which are sent to cytoplasm helps to bring components which require for protein synthesis for example ribosomes, amino acids, transport RNA. mRNA is a messenger which is produced in the nucleus when a copy of RNA of protein genetic information encodes in DNA molecule. mRNA exits nucleus and goes into cytoplasm then it interacts with cellular structures called ribosomes and functions as cell’s assemblers in the process of protein synthesis.
RNA molecule or rRNA and proteins are contained in ribosomes whereby rRNA is organized into subunits and mRNA binds to one of the ribosomes sub-unit. mRNA interacts with ribosome sub-unit and makes the approach of another RNA molecule known as RNA or tRNA. tRNA possess a sequence of three bases or anticodon which corresponds codon within the mRNA sequence where elongation takes place. If matching of anticodons of tRNA is found, tyrosine then forms a peptide bond. Amino acids are hydrolyzed from tRNA when protein synthesis is terminated after mRNA is reached
The Asian Tsunami of 2004 was located in Indonesia. The Earthquake epicentre (where it started) was in the West Coast of Sumatra.
It was a destructive plate margin, which is where the less denser plate (continental) subducts into the oceanic crust. It moved down into the mantle and moved so sudden, it caused a lot of water to be displaced.
This triggered a tsunami of 30m high.

Cyanobacteria are also very often referred to as "blue-green algae" because they are photosynthetic and aquatic in nature. They are important in the ecology as they help in forming the earth's oxygen atmosphere. Many oil deposits are attributed to the activities being performed by this group of microorganisms.
Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!
