Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.

Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Explanation:
- 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.
