<em>carbon has four valence electrons in its outermost shell .. which makes it able to form four bonds to complete its valence shell ..
it forms large number of chains with its own self which makes it useful .. also it forms bonds with oxygen and hydrogen forming large organic compounds of great importance ..</em>
The outcome of DNA replication is two DNA molecules consisting of one new chain and one old chain of nucleotides. This why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, and half is brand new.
DNA replication is the copying of DNA within the nucleus of the cell so that two full copies are present. This occurs before a cell divides. Two copies of a cell's DNA need to be present before the cell divides so that each of the resulting daughter cells will have one full copy of the parent cell DNA.

The basic activities of living things are given as follows:
- movement
- reproduction
- nutrition
- Irritability
- growth
- excretion
- respiration
Considering the information in the chart about the object:
- composed of cells
- complex chemical activities
- breaks down food to get energy
These are characteristics of living things, therefore, the object is living.
In conclusion, living things carry out the activities of life.
