False. Pure substances that cannot be broken down into simpler substances by ordinary chemical means are called Elements.
The answer is letter C. ATP.
<span>
ATP stands for Adenosine Triphosphate which is present in every cell’s
cytoplasm and nucleoplasm which is essential in all the physiological
mechanisms. It is considered as the energy currency of life or the “molecular
unit of currency”. It stores the energy
that we need every day to do our daily undertakings. The primary function of
ATP is to transport chemical energy within the body cells for metabolism. It is
said that 1 moleculte of ATP is composed of 3 phosphate groups.</span>
Answer:
The correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
Explanation:
Dr. Smith has found the bird that he considered as new species however Dr. Wilson said he will only be convinced if DR. smith could find several members of the same species. Dr. Wilson seems to be sure before considering the bird that Dr. smith found as the new species. It is because he wants to sure if it's not an unusual example of the pre-described species.
Thus, the correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
3 and 8 because it has the same shell and background
Answer:
The answer is: letter C, The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
"Endosymbiotic Theory" states that<em> certain eukaryotic organelles evolved when multiple cells merged together.</em> So, this created a <em>"symbiotic relationship"</em> among them. The organism that lives inside the other organism is called the "endosymbiont."
An example of this are the eukaryotic cells, which took in a <em>prokaryotic cell</em> (such as the ancient chloroplasts and mitochondrion). These ancient prokaryotes used to be free-living. They were often engulfed by another cell. However, in this theory, they are not killed; rather, the host cell helps it to thrive. <u>This caused the organelles to evolve together with the host cell.</u>
Thus, this explains the answer.
