Bacteria can reproduce quickly by means of binary fission. because of this, after binary fission a) the offspring will have traits of both parents. b) there is genetic variation among the offspring. c) all the offspring will be genetically identical. d) none of the offspring will be genetically like the parents.

The correct answer is C. Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission all the offspring will be genetically identical.

Explanation:

Binary fission is a form of cell division typical of prokaryotes (eubacteria and archaea), and in some unicellular eukaryotes, which is the division of a cell into two isomorphic cells.

Binary fission starts with DNA replication. In prokaryotes, DNA is separated into two strands, and each strand is molded by the synthesis of a new complementary daughter strand. Each circular DNA molecule binds to the cell membrane. The cell is elongated, which causes the two chromosomes to separate. The cell membrane then begins to invaginate to the division of the original cell into two identical cells.  

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

measure their densities same density, same sub
