ExplanationMetabolism (from Greek: ???????? metabol?, "change") is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.
In brief, the chemical processes that occur within a living organism in order to maintain life is called metabolism. - 1. Cobalt 60 is used for cancer treatment it emmits which rays?

Correct Answer: Gamma
Explanation:
Cobalt therapy or cobalt-60 therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.
Cobalt 60 is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors.
Correct Answer: TRUE
Correct Answer: Odontology
Explanation:
The study or scientific study of the structure, development, and abnormalities of the teeth is called Odontology. The science that studies teeth and their surrounding tissues, especially the prevention and cure of their diseases is called Dentology.
Correct Answer: Earth
Explanation:
Earth is not a Jovian Planet as it is a Terrestrial planet.
A planet designated as Jovian is hence a gas giant, composed primarily of hydrogen and helium gas with varying degrees of heavier elements.
Within the Solar System, four Jovian planets exist ? Jupiter, Saturn, Uranus, and Neptune. Though these planets vary in terms of size, mass, and composition, they all share certain characteristics that cause them to differ greatly from the terrestrial planets located in the inner Solar System.
Correct Answer: Specific enzymes breakdown proteins into amino acids
Explanation:
Protein digestion occurs in the stomach and duodenum in which 3 main enzymes:
1. Pepsin secreted by the stomach
2. Trypsin and
3. Chymotrypsin secreted by the pancreas
Break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
Correct Answer: Mercury was the remedy of choice for syphilis in Protestant Europe Until the early 20th century, the primary treatment for syphilis was mercury, in the form of calomel, ointments, steam baths, pills, and other concoctions Mercury was already being used in Western Europe to treat skin diseases
Correct Answer: Diagnosis of mental disorders
Correct Answer: judgement
Correct Answer: Coal is chemically complex fuel Whenever it is burned, gases are given off and particles of ash, called "fly ash," are released Release of sulfur from burning into the air The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities This stuff comes back as acid rain when it attaches itself to a raindrop Today, many of the effects of coal burning have been reduced significantly or eliminated This is super-nasty and is only stopped by buying low-sulfur coal from Montana or Wyoming The eastern power plants have to pay to move the coal from out west and this increases the price of power production
