Answer:
diffusion ( osmosis)
Explanation:
Recall that osmosis is the movement of water or liquid molecules from the region of low concentration to the region of high concentration until it's evenly distributed through a semipermeable membrane
so now it depends on the type of solution she use to check the permeability of the cell membrane
A star is provided with energy by a nuclear fusion reactions in its core. A nuclear fusion reaction occurs when the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become one helium atom.
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.
Answer:
Because of the History of DNA Mutations
Explanation:
The DNA of an organism is what causes different genetic mutations and adaptations in an organism. The DNA remains similar and had been evolving for many years but mutations can spring up at any time.
