Mutagens are agent (physical) or chemical substance that can produce mutations.
Mutagen is classified by IARC depending on their risk of cancer from class 1 to class 4. the class 1 are <span>most likely lead to the patient's tumors.
Examples of molecules classed in class 1 by IARC: Benzene (solvent), asbestos found in the old buildings, chlorambucil (chemotherapy), Cadmium (heavy metal), and o-toluidine (reagent for biochemical analysis).</span>
Answer:
Too severe
Too prolonged
Acute in nature
Explanation:
Necrosis is can lead to death of a cell, it results from external damage to cell such a s diseases and infection.
Necrosis will not allow other cellular activities because its is acute, any cell affected by necrosis will die premature leading to stop of activities on the body part.
Necrosis is a prolonged sickness that takes a long time, it may require the removal of the dead cell for rejuvenation of new body cells.
Therefore, a damage to Because will not allow for cellular adaptation in that part of the body as it leads to the death of the cell.
Prokaryotes are single-celled organisms with no nucleus, and so this would make bacteria a prime example. Therefore, depending upon the system being used, the kingdom that contains single-celled prokaryotes could be Monera, or the combination of Archaeobacteria and Eubacteria.
The kingdom systems, which were previously taught in high school, consisted of a 5-kingdom system which was later expanded to 6. The 5- kingdom included Animals, Plants, Fungi, Monera and Protists. The 6- kindgom system expanded Monera into Archaeobacteria and Eubacteria.
The "kingdom" system of classification is now generally not recognized as a valid or helpful way of classification, at least not according to modern evidence. It tends to be "paraphyletic", meaning that it describes relationships which do not match the evolutionary relationships of the organisms being described, and tends to favor human conventions rather than biological evidence. Kingdoms have generally been replaced by "domains" in terms of organizing relationships between organisms, referring to the prokaryotes, eukaryotes, and archaea, based on genetic and protein data.
The Scientific method can help resolve problems logically.
<u>Explanation:</u>
A logical and systematic approach that is used for the discovery of working of things in the world is known as Science. The scientific methods are used by the scientists for the purpose of evidences that can be measured and associated with the assumed hypothesis. The result of this method will be either supporting or contradicting to the theory.
The term "science" refers to the knowledge whose base is from some reproducible data. The result is obtained through the process of analysis and testing. It aims in finding solutions to any problem through logic and research.
