Answer:
The atomic number of phosphorus is 15. It has zero charge because it has 15 electrons.
Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.
The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
Answer:
First, we will see its body structure and collect more information about it. Second , we will see the mode of reproduction i. e. sexually or asexually.
Explanation:
We will observe structure of the body and cell. If this organism is eukaryotic and no cell wall so we can say that it belongs to kingdom animalia. We also observed its mode of reproduction i. e. sexual reproduction or asexual reproduction such as fragmentation, binary fission etc.
Answer:
option B is correct that is meiosis 2
Explanation:
the two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis
