Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.
Somatic mutation - not passed from generation to generations, occurs in body cells.
Both- changes in DNA.
<h3><u>Explanation:</u></h3>
Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.
Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.
Answer:
I think it is B) human genome project or C) harmful mutations
We are given with the data that at 10 am, the temp is 40oF. We are asked for the time when the body's temperature is equal to 80oF. In this casem we use Newtons law of cooling: T (t) = Ta + (To - Ta) e -kt. Substituing, 98.6 = 40 + (80-40) e -0.1947t. t is equal to . Hence the approximate time of death is -1.96 hrs ago or approx two hours ago. The answer is 8 am.
Gametes are the only haploid cells
Selective permeable means it selects what goes out and comes into the cell. If the cell membrane wasnt selective then things could enter the cell and destroy it.
