Answer:
Answer is all the options are correct. A, B, C and D.
Explanation:
Systematists are the biologists that developed system of classification and naming of organisms.
On this aspect, gross morphological traits described the collective structures of an organism. It referred to all the structures that are found internally and externally.
The biochemical traits and molecular traits described the genetic variability of an organism. In this case, they explained that trait is an important feature in an organism.
The behavioral traits described some actions which are particularly found to be specific to certain species of organism.
Spongy tissues composed of microscopic cells in which inhaled air exchanged for carbon dioxide during one breathing cycle are lungs.
Gaseous exchange is the delivery of oxygen from the lungs to the blood stream, and the elimination of carbon dioxide from the bloodstream to the lungs. It takes place in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
In psychology, the manipulation is described a change done, in order to obtain a certain result, but this does not guaranty that the result would be seen in future.
In this case, the lady (Bethany) switches the diet of the dog. She thinks that switching the food of the dog can help the dog to lose weight. This may or may not be true.
So, this case is an example of manipulation.
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.
