Which statements best describe how the Great Rift Valley in Africa formed? Check all that apply.
leva [86]

The answer is;

The rift valley formed when the crust pulled apart.

The rift valley formed at a divergent boundary.

Divergent boundaries occur when two adjacent convection currents in the mantle are spinning in opposite directions. This causes the upper crust to stretch creating tension due to drag in different directions on the local region. The tension causes the crust to crack severally and the middle crust block dropping in comparison to flanking regions.

How can natural processes cause rock on a mountain to become part of a beach far away.
lions [1.4K]

Weathering is a natural process by which the surface mineral of rocks is carried away by various agents .The agents can be water,wind,and ice. weathering means disintegration of rocks and the small parts are being carried away by these agents and are found on different places.Weathering of rocks depends on the many factors such as climatic conditions,type of rock,water availability and many more.The small rocks mix with soil and helps form sediment .This sedimentation helps to shape the earth's surface.This is an important part of rock cycle and is very important.

Comparing the structures of aspirin, ibuprofen, and acetaminophen, what structural do they share?
o-na [289]
<span />Aspirin, acetaminophen and ibuprofen do not have close similarities based on the classification and molecular structure. Aspirin is an acetyl derivative and have more than one crystal structure. Ibuprofen, the ones available as painkiller pills, is actually a racemic form, but like aspirin, it acts by inhibiting COX enzymes to limit prostaglandin activity. Acetaminophen is not even an NSAID because it has little anti-inflammatory activity.

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
