Why cant mutation in a human cell be passed to an offspring?
It is all dependent on where the mutation takes place. If, for example, there is a mutation in one of your skin cells, this will not be passed on to the offspring. This is because in order to pass it on to the offspring the mutation has to be present in the offspring itself. Since the offspring is created from the egg and sperm of the parents, the skin cell has nothing to do with the offspring. But if there was a mutation in the egg or the sperm, there would be some sort of mutation found in the offpspring.
What type of mutation is less harmful to an organism?
Certain gene mutations do not lead to any apparent damage. These mutations are generally the ones in which the resulting amino acid is not changed.
How does one cell created by mitosis compare to the cell it was created from?
It compares exactly the same unless mutation takes place which is some-what rare.
When electricity is passed through acid containing water what type of chemical reaction takes place?
co2 + h2o -> hco3
When does resperation takes place?
This takes place in the mitochondria.

In human reproduction when are traits passed from parent to offspring?
Hereditary traits are the traits passed from parent to offspring in human reproduction. Eye color, hair color, freckles, nose size, and others are hereditary traits.
Is crossing over takes place in sperms before fertilization?
Crossing over occurs during fertilization. This is the mixing of alleles from each of the parents in order to make the offspring.
What is the cause of genetic mutation?
genetic mutation is rare and mostly occurs by chance. Usually when DNA is being formed, there are proteins which check to assure that the order of nucleotides is correct, however sometimes this system can fail to correct problems thus a genetic mutation takes place.

What type of reaction takes place when electricity is passed through acidified water?
Electric decomposition or electrolytic decomposition takes place (both are the same and mean the same)

What type of reaction takes place when electricity is passed through water?
the electricty goes stronger
Where is urea removed from after it has passed through the blood?
The Kidneys, where the blood/urea thing takes place.
What are the four points of Lamrcks theory of evolution?
Lamarck's theory posits changes are introduced to theÊ species and passed down through the generations. Second, constant use causes a trait to manifest, disuse causes it to disappear. Third, traits changed or acquired during a subject's lifetime are passed down to its offspring. Fourth, evolution takes place gradually.
Who takes care of the crabeater seal's offspring?
The mother looks after and provides milk for her offspring.
Did the scientists of Darwin's time know how hereditary changes takes place?
No. Generally, people believed in blending inheritance ie something from each parent blended or mixied together in the offspring. The fact that inheritance is particulate ie particles (now called genes) are passed from parent to offspring and remain separate from each other, was not known until Mendel carried out his experiments on inheritance in pea plants.
