Weather is an example of rapid environmental changes.
Explanation:
Environment refers to our natural world surroundings. Rapid means fast or quick. Weather around us keeps changing as the earth rotates and revolves around the sun. It changes depending on the month of the year or may change from day to night. You can also note the room temperature at different times in a day, it keeps changing mostly minorly but it does change. There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.
Answer:
Ribosomal RNA: Structural part of ribosomes
Messenger RNA: Carry genetic information from DNA to proteins
Transfer RNA (tRNA): Transport amino acids to protein synthesizing complex.
Explanation:
Ribosomes are made up of ribosomal RNA (rRNA) and proteins. The catalytic activity for the formation of peptide bonds between amino acids during protein synthesis resides the RNA of ribosomes.
Messenger RNA (mRNA) is formed by the process of transcription during which the nucleotide sequence of the template DNA strand is copied into that of the RNA. The mRNA serves as a template for protein synthesis. The nucleotide sequence of mRNA is read in the form of genetic codes to specify the amino acid sequence of a protein. In this way, the genetic information stored in DNA is carried to the proteins.
During the process of protein synthesis, tRNAs carry amino acids to the mRNA-ribosome complex so that the amino acids are incorporated into the polypeptide. For the purpose, there is a tRNA with a specific anticodon sequence for a particular amino acid.
Acetylcholine (ACh)
Acetylcholine is an organic chemical that functions in the brain and body of many types of animals as a neurotransmitter.
Answer:
Explanation:
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
A water molecule (H2O) will have a slightly positive side, and a slightly negative side. The oxygen side of water is the one that is negative, while hydrogen side tends to be more positive. When a molecule has a half negative and half positive side like water does, it is called a polar molecule. :D
