A. The stage during which the cell carries out normal cellular functions and makes copies of its DNA.
If you'd like to know more about it, read on:
The cell actually spends most of its life in this phase of the cycle. This is the point where the cell grows and makes copies of its DNA in preparation for cell division.
Interphase is divided into 3 steps:
G1 phase - the cell grows larger and it makes copies of its organelles. (also known as the first gap phase)
S phase - the cell synthesizes copies of its DNA that is found in the nucleus.
G2 phase - it grows more and makes proteins in preparation for cell division. The cell even reorganizes its organelles in this phase.
Electron microscope is used to see nucleus of a cell clearly
Answer:
The good ozone layer can be described as the stratosphere part of the atmosphere which protects the Earth from harmful ultraviolet radiations from the Sun. The good ozone layer is however in a serious depleting condition due to human activities.
On the other hand, bad ozone layer is the part of the troposphere which is polluted. Emissions of toxic gases from human activities is the leading cause of this kind of pollution.
