Answer:
No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.
Explanation
telomerase is not responsible for causing deregulation while oncogenes cause deregulation .
Telomeres length shorten after the cell division which stops them to divide again and cell die.
Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could prevent senescence.
Answer:
The correct answer would be large NA
The resolution of a microscope is defined as its ability to distinguish two closely placed points as different entities.
The NA or numerical aperture of an objective is defined as the ability of a microscope to gather light.
NA determines the resolving power of the microscope that is, the higher the NA the higher will be the resolving power of the microscope.
However, the total resolution of any microscope also depends upon the NA of the substage condenser.
Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well.
