The cell cycle includes four phases - G1 SG2, and M. What occurs during the Sphase?
A. Prepares the cell for mitosis
B..There is intense growth and activity
C.New DNA is synthesized as the chromosomes are replicated
D.Cells increase in size and synthesize now proteins and organelles
The cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.
The cell cycle has different phases, and each phase is specific for a particular function, such as the G1 phase, which is the first growth phase. In the G1 phase, the growth of the cell takes place, such as the new protein synthesis, and then the cell enters the S phase, in which the DNA replicates and a copy is made.
Hence, the cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.

Answer:
C
Explanation:
I think it’s C because starts to replicate and yea
Answer:
Green house gases are the type of gases present in the air which have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are found naturally and are known to play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
These green house gases absorb the emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But now a days due to increased in the concentration of green house gases like carbon dioxide and methane due to pollution and deforestation causing a great problem called as green house effect which lead to global warming and it a great concern for all the people now a days.
Greenhouse gases refer to the gases, which are crucial to maintaining a suitable temperature for life on Earth. Examples are methane, carbon dioxide, and nitrous oxide.
Greenhouse gases such as water vapor, methane, fluorinated gases, and carbon dioxide trap the sunlight and raise the temperature of the Earth keeping it warm.
The gases are a concern for the environment and life on earth as in the absence of these gases, the Earth's climate will be extremely cold and chilly.
These gases act as a protective blanket, saving them from infrared rays and other harmful rays. Also, the increased emission of these gases is leading to global warming, which is one of the major threats to life on Earth.
Thus, greenhouse gases are essential but their increased emission is a major concern for the planet.
