Almost all areas of Biology have developed in the twentieth century, but few areas have gained a lot of importance. Some of these are :
1. Genomics and Genetics
2. Biotechnology
3.Cell and molecular biology
Damage to heart valves can lead to heart murmur.
Explanation:
Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.
The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
The types of damage to the heart valve that may lead to heart murmurs are:
Mitral valve prolapse, Mitral valve or aortic stenosis and Mitral or aortic sclerosis.
Sometimes, the murmurs do not signify a serious condition but under certain condition they may indicate the risk of heart failure.
Hydrophytes are plants that can live or adapt in water or any aquatic environments either fresh or salt water. The cypress, pond lillies and cattails are examples of hydrophytes or what they call aquatic plants. Therefore, the answer is eucalyptus since it's a mesophyte.
Answer:
B) Golgi body
Explanation:
Golgi body is a sub cellular structure that is involved in modifying, synthesizing, packaging and delivering proteins.
Mitochondria are responsible for the production of the majority of the cell's energy in form of ATP. The process requires oxygen and thus it is called cellular respiration. It is a very effective process that produces 38 ATP molecules per oxidized glucose molecule.
The lack of mitochondria in the body would have the same result as the lack of oxygen: anaerobic respiration. This type of energy production is very ineffective and it results in only two ATP molecules. Thus, if people would loose their mitochondria, they would not survive for very long as anaerobic respiration does not produce enough cellular energy.
Furthermore, anaerobic respiration also has a detrimental side effect: lactic acid. This chemical substance results during the conversion of glucose into ATP. Its presence and accumulation increases the acidity in muscle cells and is responsible for the "burning" sensation after intense physical activity.
In order to remove the lactic acid, it is required the action of primarily the liver and kidneys as well as skeletal muscles to a lesser degree.
In conclusion, a person would not be able to survive for very long without mitochondria. Anaerobic respiration is meant to supplement cellular respiration for only short periods of time and not replace it.
