Answer:
Breathing is a physical process that involves various organs like the lungs, windpipe, nose, and others for exchanging the gases that are inhalation or taking of oxygen and expelling the carbon dioxide in the body.
Respiration is a chemical process that takes place inside of the cell by breaking the sugar using oxygen taking from breathing to produce energy. These both processes are different, however, interrelated to one another as breathing provides oxygen for respiration, and respiration gives up carbon dioxide to expel out by breathing.
It contains monosaccharides, the simplest carbohydrate
Compounds that inhibit receptors by preventing the natural messenger from binding are known as antagonist.
Antagonists are molecules that will block the binding of the natural messenger at a receptor molecule. As a result, the signal which is usually produced by a receptor-messenger coupling will be inhibited. <span>An antagonist can be a drug that blocks a biological response by binding to and blocking a receptor.</span>
Eutrophication is the input of excessive nutrients into fresh surface waters. Nutrients can cause algal blooms. Some of these algae can be toxic, and algal death can also result in anoxic conditions, leading to fish deaths. Some indicators of eutrophic conditions can be high measures of important nutrients such as phosphates and nitrates. Another indication of eutrophication can be high concentrations of algal cells. Finally, low dissolved oxygen can indicate eutrophic conditions.
Answer:
Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.
