How do scientists decide when to change or modify their understanding of a particular topic?​
Natali5045456 [20]

Answer:

they carry out experiments to understand it

Explanation:

Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).

A man who smokes heavily has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma
Naya [18.7K]

Answer:

The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.

Explanation:

  • The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
  • The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
  • In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
  • The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
  • Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
  • However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
  • Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.
