Why does the cell replicate its DNA?
Verizon [17]

Explanation:

When cells asexually reproduce they split off from itself, and they have to replicate their DNA so both cells will have it because DNA is what tells the cell what to do, and how to work. The DNA will tell the cell parts all how to do their jobs, and will let the cell know when it should split off from itself. The DNA controls everything in the cell so without it the cell wouldn't know what to do.

Novosadov [1.4K]

Answer : The correct option is, U

Explanation :

As we know that there are four states of matter which are solid, liquid, gas and plasma.

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.

For example : Helium gas

Plasma state : In this state, the stars, atoms lose their electrons at very high temperature. The mixture of electrons and nuclei that result is the plasma state of matter.

For example : Sun

In the given incomplete table,

T = solid state

W = example : copper

U = gaseous state

X = example : water

V = plasma state

Hence, the gas would be placed in 'U' box.
