Describe possible causes and effects of ozone depletion?
this is not halping me
How does the possible impact of a chromosomal mutation that occurs during meiosis differ from that of a similar event that occurs during mitosis of a body cell not involved in reproduction?
If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful. If instead it occurs during mitosis, it won't get inherited by the offspring, so any harmful effects are limited to you. Basically it's like getting a wound, you may heal or not, but you won't pass that wound on to any offspring you may subsequently have.
Is the only possible source of new genetic material?
mutations recombination/crossing over in mammals
The mutation that results in sickle cell anemia produces effects that are?
Both harmful and positive
What is a possible benefit to a random mutation in an organism?
II and IV only

What would the possible effects be in mutation in a skin cell?
melanoma, apoptosis, squamous cell carcinoma to name a few.
What kind of mutation is a tumor?
it is a mutation like PLX4032 it reverses the effects of a mutation found in certain tumors
What effects can mutation have a virus?
They create genetic variations.
What is the effects of mutation?
A mutation is a permenent in DNA sequence of a gene,mutation in a gene's DNA sequence can alterthe aminoacid sequence of the protein encodedby the gene.
What are some general effects of a mutation?
Some general effects of a mutation are changes in DNA/RNA sequences and plausibly alteration of the product of a gene or the prevention of a gene from functioning properly.

What name do scientists use to describe a change in a gene?
mutation.
What are the signs of a mutation?
Abnormal cell growth and foreign side effects.
What is pleiotropism?
it refers to gene or mutation that has multiple effects like polyphenotype
What is an inversion mutation?
An inversion in meteorology is when atmospheric pressure causes an abnormal condition. An example would be that the pressure causes warmer air to sink closer to earth's surface and cooler air to rise higher. When this inversion happens, one of the effects is that pollution and smog stay trapped within our atmosphere.
Can you have an extra rib?
If a mutation caused it, it's possible.
