answer:
this is the cell theory, which was proposed by Theodor Schwann in 1839
explanation:
- in biology, cell theory is the historic scientific theory
- it states that living organisms are made up of cells, they are the basic structural/organizational unit of all organisms and all cells come from pre-existing cells.
Answer: they use vesicles for cell transport and they require energy for cell transport
Explanation:
Natural selection is the differential survival and
reproduction of individuals due to differences in phenotype. It provides a
viable explanation for adaptation and speciation as it explains the change in
heritable traits characteristic of a population over time. Changes that allow an organism to better adapt
to its environment will help it survive and have more offspring. Natural
selection can change a species in small ways, causing a population to change
color or size over the course of several generations. Given enough time and
enough accumulated changes, natural selection can create entirely new species. It
can turn dinosaurs into birds, amphibious mammals into whales and the ancestors
of apes into humans.
I think the correct answer from the choices listed above is the third option. The DNA is used as a molecular clock in the sense that the <span>percent of carbon in DNA is compared between parent and offspring. Hope this answers the question. Have a nice day.</span>
It’s either americium or californium but i think it would be americium
