A strand of DNA is a polymer of nucleotides joined by covalent bonds between the deoxyribose of one monomer and the phosphate group of the next monomer.

DNA is the polymer of the nucleotides. In the DNA Nucleotides are bonded by phosphodiester bonds.

A nucleotide is composed of a nitrogenous base, deoxyribose sugar, and a phosphate group.A nitrogenous base can be purine or pyrimidine.Purine includes Adenine and Guanine.Pyrimidine includes Cytosine and Thymine.

Therefore, a strand of DNA is a polymer of nucleotides joined by covalent bonds between the deoxyribose of one monomer and the phosphate group of the next monomer.

A strand of DNA is a polymer of nucleotides joins by covalent bonds between the deoxyribose of one monomer and the phosphate group of the next monomer.

Explanation: Nucleotides are the building blocks or monomeric units of DNA. Nucleotides have three components: A nitrogenous base, a pentose and a phosphate group. Nucleotides have two kinds of pentoses: deoxyribose and ribose but only deoxyribose is found in DNA. The nitrogenous bases are derivatives of two parent compounds pyrimidine and purine. The two major purine bases are adenine and guanine while the pyrimidine found in DNA are cytosine and thymine. The successive nucleotides of DNA are covalently linked through phosphate group bridges in which the 3'-hydroxyl group of one nucleotide unit is joined to the 5'-phosphate group of the next nucleotide by a phosphodiester linkage.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

Why are volcanos activity a good example of system interactions?

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.
