A bond, called the glycosidic bond, holds the base to the sugar and the 3′-5′ ("three prime-five prime") phosphodiester bond holds the individual nucleotides together. Nucleotides are joined from the 3′ carbon of the sugar in one nucleotide to the 5′ carbon of the sugar of the adjacent nucleotide. The 3′ and the 5′ ends are chemically very distinct and have different reactive properties. During DNA replication, new nucleotides are added only to the 3′ OH end of a DNA strand. This fact has important implications for replication.
Answer:
Below is the drawn model to show the flow of energy from a nonliving source to an herbivore.
Explanation:
The model given below shows how energy from a nonliving source is transferred into a herbivore. It shows that solar energy that is produced by the sun (a nonliving source) is captured by the plants, which use this solar energy to convert it into chemical energy. After that, this chemical energy is transferred to a herbivore that feeds on these plants.
Answer:
Harmful algal blooms in freshwater lakes and rivers, or at estuaries, where rivers flow into the ocean, are caused by cyanobacteria, also known as "blue-green algae". They can produce hazardous toxins, such as microcystins, a neurotoxin which destroys nerve tissue of mammals.
