Answer: The molecules that make up the "rails" or sides of the DNA structure are deoxyribose and phosphate
Explanation: A DNA is a double stranded helix made up of nucleotides. A nucleotide is made up of three parts: a deoxyribose sugar, a phosphate group and a nitrogenous base. Nitrogenous bases found in DNA are Adenine, Thymine, Cytosine and Guanine. The bases pairs with each other to form the rungs of the ladder while the phosphate group and deoxyribose sugar forms the rail or the backbone. The rail containing phosphate groups and deoxyribose sugars is called the phosphodeoxyribose backbone.
In the experiment, the independent variable is the drug amount. Experiment group is given certain amount of drug, control group is not given the drug. The dependent variable is the body fat. I think you means the control is the living environment including food and water.
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. The gases are the fundamental cause of the greenhouse effect. Increase in the amount of greenhouse gases in the atmosphere enhances the greenhouse effect which is creating global warming and consequently the climate change. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries. .
Animals and plants get rid of carbon dioxide gas through respiration. Carbon may also move from fossil fuels to the atmosphere when fuels are burned. Burning of fuels to power factories, power plants, cars and trucks makes carbon to enter the atmosphere as carbon dioxide.
Answer:
Cholesterol
Explanation:
Cushing Syndrome occurs as a result of exposure of the body to elevated levels of cortisol hormone (stress hormone) for a long time. The elevated level of cortisol which is a steroid hormone, results from increased synthesis of cortisol in the adrenal glands. Cortisol is synthesized from a substrate called, cholesterol. Cortisol synthesis occurs in the zona fasciculata of the adrenal cortex and controlled or regulated by the hypothalamus-pituitary-adrenal axis or HPA axis.
Cholesterol, which is an important substrate in cortisol synthesis, is a lipid usually found in cells and plays an important function in hormone synthesis, food digestion and synthesis of Vitamin D.
