<span>A genetic mutation occurs when there is a permanent change in the nucleotide sequence of the DNA. The error falls in to 3 main groups; Deletion, substitution, or an addition of base pairs. The main reason why mutations are fatal are because of the rapid cell development that can cause cancer.</span>

During replication, a genetic mutation can occur due to;

• The disappearance of the nucleotide base.

• Addition of any nucleotide in a DNA sequence.

• Substitution of nucleotide base pair.

Further Explanation:

Genetic mutation can develop due to change in a particle sequence of the DNA. It can affect a single sequence or can affect a large sequence of DNA. Genetic mutation can be of two types:

• Somatic mutation: These are the mutation that can develop during the life span of an individual. They are not like hereditary. They can develop due to UV-rays.

• Hereditary mutation: These are the mutation that can pass from parents to offspring. They are also referred to as a germline mutation. They pass through the egg or sperm cell.

During the process of replication, genetic mutation mainly develops due to:

• Deletion: In this, disappearance or deletion of a specific nucleotide can occur and develop a mutation in the DNA. This is an example of a point mutation.

• Duplication: In this, duplication of a particular base pair occurs.

• Insertion: In this, the addition of a specific nucleotide base or nitrogenous base can occur.

• Substitution: In this, the normal base pair is substituted by a different base pair.

what role does fact finding play in the arbitration and mediation process between labor and management

maks197457 [2]

Mediation is the process of two conflicting groups coming together to find a middle term. It is at times the negotiation with the difference and it is normally supervised by a person in authority who oversees and leads the processes. If the mediation fails them the conflict is placed under arbitration. The process of arbitration is fully directed by an arbitrator who has same powers as the judge but is limited to the conflict that is being solved. The arbitrator is there to impose a final decision or come up with the resolution to the conflict in the fairest way. He should follow justice after listening to both conflicting side. The arbitrator is not there to find the middle term to be agreed by the two sides.

Suppose that Zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated Zonos

Vesnalui [34]

Answer:

(c)-All results for the experimental groups involving wing surgery would be invalid.

Explanation:

The study researcher shown in the above question noted that flies that underwent wing surgery were more attacked than those that received no wing treatment. However, the researcher does not show the study variables and, consequently, does not show any relationship between the variables and the research result. For this reason, we can state that based on this result, all results for experimental groups involving wing surgery would be invalid.
