Answer:
Because it is only possible to be 100% sure that two species are closely related, in genetic terms, when the DNAs of these species can be analyzed. This analysis is only possible through molecular tests.
Explanation:
Molecular tests are bikini techniques that can analyze species at the molecular level, more specifically, these tests can deeply analyze the DNA (or RNA and proteins) of a species giving precise results on the molecule and allowing scientists to study it deep.
In studies, where the scientist wants to know how the species are genetically related, it is common for molecular tests to be introduced, as a way for the scientist to be 100% sure of the relationship between the species.
Explanation:
So when u take antibiotics you kill lots of the bacteria. however you don't kill all of them. the bacteria that is left over hasn't been killed because they are resistant to the antibiotics taken. if left these bacteria will reproduce and build and species resistant to that type of antibiotics which can be incredibly dangerous. this is why it is necessary to finish your full antibiotics course so even if u feel better just to make sure you kill all the bacteria.
Explanation:
The way the Cell cycle works helps us keep us alive as long as usually do. An example is when you bite your cheek, you may kill some cells by it but your alive cells will replace them by creating more. Now without the cell cycle here's what would happen, You bite your cheek and your cells die forever causing your mouth to be dryer, weaker and to lack enzymes ( enzymes help brake down your food and ready it to go threw your digestive system ) So imagine every time you get hurt and your cells just keep dying without being reborn that's like as if everyone stopped creating children eventually the human race would end, If the cell cycle does not do its job eventually you will get weak and die. that's why the Cell Cycle is important to any living things well being especially if its Multicellular.
Hope this helps! <3
