Genetic alteration refers to altering DNA sequence. Gene alteration forms genetically modified products that modifies the gene sequence. DNA consist of two long chains of nucleotides that are twisted and joined together in hydrogen bonds. These DNA cannot be altered in nature but gene expression can be altered.
Answer:
Digestion is the process of converting complex food any individual eats, into the smaller components and nutrition that is absorbed and assimilated into the body to produce energy and nutrition for the cell and body. The digestion process takes place in the digestive system that includes the gastrointestinal tract and organs like the liver and pancreas.
It includes ingestion of food through the mouth or buccal cavity, propulsion of food, physical digestion by making it small pulp with help of peristalsis, chemical digestion by the enzymes and acid, absorption through the intestine into the blood, and defecation of waste.
Answer:
Global warming is caused by the greenhouse effect caused by greenhouse gases, such as carbon dioxide, in the earth's lower atmosphere. A release of carbon dioxide into the atmosphere by carbon sources such as fossil fuel burning increases the greenhouse effect hence increased global warming. Another effect of higher carbon dioxide levels in the atmosphere is oceans acidification. The oceans will absorb more carbon dioxide and form more carbon acid hence lowering the pH of the waters. To alleviate this phenomenon, carbon sinks need to be protected such as forest because they sequester carbon dioxide from the atmosphere and store it as carbohydrates in their biomass.
