DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Human DNA has around 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA
Formula. The chemical formula that represents all of these stages throughout the cellular respiration process is: Spelled out, it states that glucose and oxygen yield carbon dioxide and water and a maximum<span> of 38 molecules of ATP. The ATP molecules are now used as the energy currency of the cell.</span>
1. water temperature of lakes and rivers rise - nuclear power plant. Water is used as a coolant to maintain the temperature of nuclear reactors. and the resulting water is warmed up.

2.carbon monoxide pollutes air - </span> internal combustion engine. Internal combustion engines release fumes of carbon monoxide.
<span>
3. fly ash of soot in air - </span>coal-burning power plant. Coal burning plants release ash produced in small dark flecks.<span>
4. soil contamination of water resources - </span>DDT spraying in agriculture. DDT washes off agricultural land into water resources.
<span>
5. sewage contamination of water resources -</span>population density. Urban areas produce a low of sewage, which is usually treated before being disposed of in rivers or the sea.

6. excess plant growth in the lakes or rivers - </span>phosphate detergents. In many rivers, algal growth is limited by phosphate. Once excess phosphate is released to rivers, exponential algal growth can occur.<span>
7.reduces farmland and plant life to cleanse air - </span>urban sprawl. Urban sprawl uses up land for houses in an inefficient manner that could have been used for farming or natural areas.

Nucleic acids are the biopolymers, or large biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA . They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
Answer:
they move to an area with lower concentration.
Explanation:
Air particles always travel from an area where they are high in concentration to an area where they are low in concentration. as we can see that on the left hand side the numbers of o2 and co2 molecules are balanced.
