Why does complex multicellular organisms need a nervous system?
Complex multi cellular organisms need a nervous system to be able to contact the brain and be informed on which tasks need performing. Hope this helps...
Multicellular organisms are able to make new cells to replace damaged cells?
Mitosis
Why do humans have multicellular cells?
We need to be multicellular, because we need all the different types of cells for what our body's systems do. Being multicellular gives humans more capabilities that other organisms might not be able to do. Humans would not be built the same way that we are now if we were not multicellular, we would have a lot less functions.
How do single celled organisms have movement?
Multicellular organisms can move in different ways depending on their size and shape. The term multicellular refers to most living things on the planet so the question cannot be answered without generalising.
What are 3 benefits of being multicellular?
multicellular organisms are able to do much more specialized functions than single cell organisms. for example a dog can see visible light waves because it has eyes that are specially built for seeing some types of light while a single cell organism cannot see light or do very many things besides eat.

What are some advantages in being multicellular?
Multicellular organisms can become much larger than unicellular organisms, and store a lot more resources within them due to assimilation, and thus can tolerate more extreme conditions without food. Multicellular organisms are also able to exist in multiple media, and are able to have specialised cells in their bodies so to specialise areas of their body.
Do cells ever die?
Yes. Cells die all the time. If they didn't, multicellular organisms would not be able to function.

In what sense can protists be considered the most complex types of cells?
Protists are the most diverse group of organisms on Earth... they're kind of the group that evolutionary biologists and scientists can't place in any other of the animal, plant, bacteria, fungi groups so they get a group of their own. So, some are more complex than bacteria, and some aren't.

Where does it live unicellular organisms?
Unicellular organisms can be found everywhere. But they are mostly known for being able to live in extreme environments such as hot springs, volcanoes, and areas below zero degrees.
How does the environment of cells differ for a unicellular and multicellular organism?
Unicellular and multicellular environments may vary. Multicellular organisms are able to do more functions, and unicellular is one-cell, so their functions are limited, although some unicellular ones such as thermophiles and photosynthetic bacteria can thrive in any environment with sun or heat. Multicellular ones like animals, can be found anywhere active, although different types exist in different places.
What can be a disadvantage for multicellular organisms?
Some of the structures formed by specialized cells are dependent upon other structures. If one structure within the organism is unable to function, other structures may not be able to function either. Muliticellular organisms need more energy than single-celled organisms to function.
What process did Darwin's books suggest that organisms evolve through?
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
