A mutagenic agent is any chemical, physical or biological compost that can induce a mutation in the cell's DNA, making this mutation pass to the next generation.
Mutagenic agents are widely used in the fields of biotechnology, genetic engineering, medicine and agroindustry. This is because these agents have helped in the advancement and development of new technological tools.
In genetic research some bacteria and viruses are used by agribusiness companies to obtain transgenic beings. These mutagenic (biological) agents act as vectors of laboratory-created genes that will insert these genes into an organism to be modified. It could be, for example, a gene that will improve maize resistance against a pest. Thanks to mutagenic agents, this genetic information can be passed on to the organism, in this case, the plant.

The answer is D. In a
geological era, when the plants and animals
in the then environment die, they get buried
in sediments. These sediments are covered
by other sediments of another geological
time within which are the remains of dead species
of the then geological era. These sediments from different geological times have different properties hence
form visible strata that can be studied to identify the kind of environment in the then geological time. Their
fossils can also be studied to identify
the kind of species that roamed the earth during the time.
