Mutations can occur as a result of many factors, including ultraviolet light or environmental pollutants such as pesticides and
cigarette smoke. Which of the following best describes the most likely consequence of these mutations in cells? The cells can become resistant to drug therapy.
The cells can become phagocytes.
The cells can become unable to divide.
The cells can become cancer cells.
Mutation causes cancer which is in general acquired i.e developing due to the habits of an individual. Some common factors that lead to acquired mutation are – smoking, exposure to ultraviolet radiation, viruses injection etc. Such factor interrupts with the genetic code of the normal cell and lead to uncontrolled division of cell thereby causing cell mas or cell clot which eventually becomes tumor and cancer.
The veinlets form a network in the leaf lamina that is why the type of venation reticulate meaning network. So all dicots have dicotyledonous seeds, a tap root system and leaves with reticulate venation. ( with some exceptions of dicots having parallel venation in leaves like Calophyllum)
