The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells. The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

Where is the rainshadow area on the Big Island of Hawaii? Please help
Answer:
Applied to the Big Island, since the trade winds blow from the northeast and must pass over the mass of Mauna Kea and Mauna Loa, it means that the Hilo side is considerably rainier than the Kona side. The best place to view this rain shadow effect is to drive from Kohala to Hilo through the town of Waimea.

A student is investigating the process of osmosis. She fills a medicine dropper with red
blood cells. Next, she creates a saline solution that is isotonic to the red blood cells.What will most likely happen to the red blood cells after they are placed in the
solution?
A. Water will exit the cells and cause them to shrink in size.
B. Water will enter the cells and cause them to grow in size.
C. Water will neither enter or exit the cells and their sizes will remain the same.
D. Water will enter and exit the cells at a steady rate and their sizes will remain
the same.
Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.
Explanation:
Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.

a group of unicellular organisms that live together but have on relationship to one another
The group of unicellular organisms that live together but have no relation to one another is called colonial organisms.
What are colonial organisms?The organization of cells leads to their efficiency. The organization of cells leads to the formation of tissues and organs which leads to the efficient functioning of an organism.
The organization of cells is not only seen in the multicellular level of organization. It starts from the organization of molecules to form structures like proteins and nucleic acid.
Unicellular organisms are able to live and survive independently and perform all life processes necessary for their own survival. But, bacteria are often found to live together in colonies.
A colony is a group of individual organisms that live close to each other. They live together because they are stronger in a colony. A colony of bacteria can protect themselves, acquire their nutrition or attack a host in a better way.
Therefore, a group of organisms who live close to each other and have no relationship is called colonial organisms.
