A) a large group of cells that grew without regulation.
A tumor is where there is a mutation that causes cells to lose their ability to self regulate, so they reproduce too fast and become unspecialised, causing a tumour.

Answer:
The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.
Explanation:
The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.
When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.
- Answer: 32 molecules of DNA would be after four PCR if the initial reaction mixture contained two molecules
- After 'n' rounds of the polymerase chain reaction, it is feasible to produce 2 n DNA molecules from a single DNA template molecule (PCR). Therefore, 2 to the power 4 = 16 DNA molecules will be produced after 4 PCR cycles
- If two molecules are doubled four times, 32 DNA molecules are created.
Explanation:
The PCR method is what?
The highly sensitive PCR method enables quick DNA amplification of a particular section. Using visual methods based on size and charge, PCR may detect and identify gene sequences by producing billions of copies of a certain DNA fragment or gene.
What does a PCR have to accomplish?
A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis.
What are the three main PCR steps?
For any DNA synthesis reaction, there are only three easy stages that must be completed: First, the template is denaturated into single strands. Next, primers are annealed to each original strand to synthesise new DNA strands. Finally, the new DNA strands are extended from the primers.

The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.
