Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state.
Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division.
Answer:
Radio waves are used to transfer signals to and from the cell phone. Modern mobile phone networks use cells because radio frequencies are a limited, shared resource.
All of the cell sites are connected to telephone exchanges (or switches), which in turn connect to the public telephone network.

Answer:
<h3>33.3%</h3>
Explanation:
profit percent = Sp-Cp/Cp * 100%
Sp is the selling price
Cp is the cost price
Let the selling price of the article be x
If it is sold with a profit of 25% of selling price, then;
Profit = 0.25x
Since Profit = Sp - Cp
0.25x = x - Cp
Cp = x - 0.25x
Cp = 0.75x
Substitute into the formula
Profit percent = 0.25x/0.75x * 100
Profit percent = 0.25/0.75 * 100
Profit percent = 1/3 * 100
Profit percent = 33.3%
Hence the profit percent is 33.3%
