Fossils almost never contain DNA. So how can we know how closely or distantly related fossil organsims are to living organisms

Biology

Nostrana [21]3 years ago

While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.

3.a An antibiotic is added to a large population of bacteria. Explain why not all bacteria die?
drek231 [11]

Answer: Antibiotic Resistant Mutation

Explanation: Not all of the bacteria die because there are individuals in the population that have an antibiotic resistant mutation, which causes them to be adapted to dealing with the antibiotic. There will be a large population of bacteria again because the ones with the mutation survive, reproduce, and pass the antibiotic resistance trait on.

Based on the seed experiment in the Poop Lab, which seeds do you expect to sprout and grow?
-Dominant- [34]

Based on the seed experiment in the Poop Lab, the seeds that are expected to sprout are the seed in the elephant poop while the seeds in the soil are not expected to sprout.

<h3>What was the Poop Lab?</h3>

The main idea of the Poop Lab is to compare the growth of seeds that have gone through the digestive system of an animal, in this case, an elephant, to a seed that has not.

The seed that had gone through the digestive system was observed to have sprouted but the seeds in the soil did not. This experiment demonstrates the role animals such as elephants play in shaping the ecosystem through seed dispersal.

The seed that passed through the digestive system of the element and then passed out into the poop received enough nutrients for growth.

However, the seed in the soil does not receive adequate nutrients.
