During S phase, DNA replication occur during the cell cycle for each daughter cell to receive a complete copy of DNA.
A cell'sgrowth and division are accompanied by a sequence of processes known as a cellcycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Following this, the celldivides into two daughter cells, distributing one copy of the duplicated material to each. When each daughter cell has its own outer membrane around it, the cell cycle is finished.
Genetically speaking, the parentcell, together with the two brand-new daughter cells, are all the same.
Prior to mitosis and cell division, DNA replication takes place during the S phase (also known as the Synthesis phase) of the cell cycle.
Thus, the DNA replication occur during Sphase of the cell cycle.

Answer:DNA replication occur in mitosis process at( S-synthesis) interphase stage
In multicellular organism
It is multicellular.
B.
It does not have a nucleus.
C.
It possesses a membrane-bound nucleus.
D.
It possesses a hard outer shell.
The smallest living organisms which are capable of survive independently in nature are those which possesses a membrane-bound nucleus. Thus, the correct option is C.
A cell is the fundamental unit of life. It is the structural and functional unit of all living organisms. Cells are classified on the basis of its structure, function and origin.
Cells contain a nucleus which contains all the genetic material of an organism The genetic material is stored in the form of nucleic acids such as DNA or RNA. A membrane-bound nucleus is present in all eukaryotic organisms. This membrane helps to separate the nuclear material from the cytoplasm.
The presence of a nucleus is important for all the living organisms as this nucleus contains genetic information which is transferred to the offsprings and hence responsible for reproduction and maintaining the number of organisms.
Therefore, the correct option is C.

Answer:
oxidation
Explanation:
From the moment we perform body movements, there is a greater demand for oxygen. This is due to the need for oxidation of energetic substrates such as free fatty acids and circulating glucose. Thus, aerobic metabolism is potentially increased to supply the energy required by muscle contractions, whatever their intensity. From this we can say that breathing hard during exercise brings oxygen to the muscles, which helps the oxidation process release energy to fuel the workout.
