Sex cells
A mutation in a cell's DNA can change the way the cell functions, leading to abnormal behavior that sets it apart from normal cells. This altered behavior can result in the cell growing uncontrollably, not responding to signals to stop growing, or behaving in ways that are harmful to the body.
The sequence of the nitrogenous bases changes (and sometimes some bases are added to the sequence or completely removed).
Mutations which do not occur in sex cells are not passed on to the next generation. The mutation will only affect the individual. They could therefore have normal offspring.
A mutation in a human skin cannot be passed on to an offspring, since it is only a somatic mutation which is acquired. The mutation that can be passed on to an offspring is called a germline mutation, which happens in the egg and sperm.
Yes, mutations are passed on to new cells during replication. If a mutation occurs in a cell's DNA, it will be present in all daughter cells that are produced through replication. This can lead to genetic variation and evolution over time.
Absolutely, mutation can occur in any cell, human or non-human. Mutation has a number of causes, but radiation is probably the most significant. If the DNA is struck by radiation (even solar radiation, which is to say, sunlight) it will be altered, hence there is a mutation.
A mutation is a permanent change in the gene or chromosome of a cell that can result in altered characteristics or function. Mutations can arise spontaneously during cell division or in response to external factors such as radiation or chemicals. These changes can be inherited or occur randomly in somatic cells.

If the mutation happens in the germ cells, only then it wil be passed on to the offsprings. But, if it happens in some other cell, then it won't be. Such a mutation is Superficial. Like, if we cut the tail of a mouse, no change occurs in the germ cells. So the next generation will still be born with a tail.

A mutation in egg cells
Mutations which do not occur in sex cells are not passed on to the next generation. The mutation will only affect the individual. They could therefore have normal offspring.
You can have a baby with physical/mental deformities or death of the child.
It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.
