Answer:
d. Storms produce large waves that deposit sand bars along shorelines.
Explanation:
Large waves are the product of distant storms, which occur during the summer months. Such waves bring more gravel and sand to the shorelines than they carry. As a consequence, the coast is gradually being upgraded.
Along many shores it is possible to notice the occurrence of material deposition in one place and erosion in another. A good example is the south coast of England. In the Fairlight area, several meters of shoreline are carried off each year, and apparently a new bay is created in the area. Just a few miles further east, at Dungeness, the pebbles formed a cape shaped like a nose ("ness" in the name of the place means "nose"), which gradually erupted into the sea. Cape Canaveral, Florida, was similarly created.
Like DNA, RNA contains four nitrogenous bases. Three of them are the same as those found in DNA. The one that is different is called uracil. The five-carbon sugar in RNA is called ribose.
Uracil is a crystalline organic molecule, and a component of the ribonucleic acid (RNA). The RNA molecule is made up of a sequence of nucleotides, which individually contains a five-carbon sugar (ribose), a nitrogenous base, and a phosphate group. Uracil is one of the four nitrogenous bases present in the nucleic acid of RNA. The others are adenine, cytosine, and guanine, and are represented by the letters; A, G, C and U. In DNA (deoxyribonucleic acid), the uracil nucleobase is substituted by thymine.
Answer b is the best example
