Answer:
Bacteria reproduce by binary fission
Explanation:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.
Binary fission begins when the DNA of the bacterium divides into two (replicates).
Answer:
Left amount of Polonium-210 after 115 days will be 4.5927 microgram
Explanation:
We have given initial mass of Polonium-210 
Decay rate x= 0.502% = 0.00502
Time t = 115 days
We have to find the left amount of Polonium -210 after 115 days
We know that left amount is given by
So left amount of Polonium-210 after 115 days will be 4.5927 microgram
60 years is three half life for the substance, so 40*1/2^3=5
Answer:
Explanation:
An organism can't chose to have a mutation because it depends on the way they are born. If they are missing some type of mineral, (Protein, Vitamin, etc.) they will have a mutation because they're missing that. Well, something similar to a mutation is natural selection and genes.
