which are similar structures shared by different
evidence for evolution includes the presence of
species
gradual structures
vestigial structures
integrated structures
homologous structures

The correct option is D) homologous structures

Explanation:

In evolutionary studies, a homologous structure can be described s a similar structure which is present in different species. This is because these spices might have a common ancestor in the past. For example, the forelimbs of humans and bat. They perform different functions but their structure is similar. They are also derived from the same embryonic origin. These similarities show that the bats and humans might have shared a common ancestor in the past.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
