Answer:

See the answer below, please.

Explanation:

DNA is made up of nucleotides, which are composed of: phosphate group, sugar (deoxyribose) and nitrogenous base (adenine, cytosine, guanine or thymine). These nucleotides join together to form a double spiral-type chain (the double helix). In the base matings by hydrogen bonds: adenine pairs with thymine, and guanine with cytosine (this is inside the double helix and the sugar-phosphate skeleton on the outside).

<h2>Down Syndrome</h2>

Explanation:

Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21

  • Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
  • Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
  • Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
  • With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
  • Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus

The Changing Forms of Carbon
Tom [10]

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.

The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.

Hope you could get an idea from here.
