Well, the first thing you need to understand to answer this question is Darwin's theory.
What happens is that, for example, a species of giraffe has a small neck, what happens to it is that this species can't get the food on top of the trees, and then, this species will most likely die in a couple of time. But through mutation, this species can generate another one that fits well into that environment, being capable to get food on the ground or even with a bigger neck, and by that, the survival of the species is guaranteed for now. Let's think about humans for a second, we are a species that went through evolution as well as all the species on earth right? But how did that happen? It's easy, if one of our ancestors for example, didn't have the right DNA/genes that gave us a feature that protected us from some diseases, we would probably be dead.
And be careful, a gene can be anywhere in a chromosome, that's why it's so hard to study and map it. The same thing happen to cells, if they dont adapt well, they die or adapt on the next generation.
Answer:
They concluded that the cell is eukaryotic cell.
Explanation:
Prokaryotic and eukaryotic cells are the two types of organisms. Prokaryotic organisms are the organisms made up of prokaryotic cells and eukaryotic organisms are made up of eukaryotic cells.
Prokaryotic cells do not have a nucleus and other membrane-bound organelle and eukaryotic cells have a nucleus and other membrane-bound organelles like mitochondria.
Therefore if the cell has mitochondria they must conclude that the cell is eukaryotic because the prokaryotic cell does not have mitochondria as it is a membrane-bound organelle.
It can withstand high heat and still add nucleotides which is used in the PCR.
Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
Answer:
Carbon dioxide because theres air water and sun and the air is oxygen
