Which of these organisms is considered the most complex?
Vertebrates
LEVELS OF ORGANIZATION:
1. Atom- Atoms are the smallest unit of matter.
2. Molecules- Molecules are created when two or more atoms bond together.
3. Cells- Cells are the smallest working unit of a living thing. Cells are made up of various molecules and atoms, and they use various molecules and elements to function. (NOTE- An element is a composed of many of the same exact type of atom.)
4. Tissue- A tissue is a group of similar cells performing a specific function.
5. Organ- An organ is a group of tissues performing the same function. (Example= brain or heart)
6. Organ System- An organ system is a group of organs performing the same function. (Example= large intestines)
7. Organism- An organism is a living thing with multiple organ systems working together to maintain a comfortable inner environment.
8. Species- A species is a group of living things that can interbreed to produce fertile offspring.
9. Population- A population is a group of the same species living in a certain area.
10. Community- A community is all of the living things that live in a specific area.
11. Ecosystem- An ecosystem is all of the living (biotic) and nonliving (abiotic) factors that make up an area.
12. Biosphere- The biosphere is all parts of the Earth where living things can survive.
Atom > Molecule > Cell > Tissue > Organ > Organ System > Organism > Species > Population > Community > Ecosystem > Biosphere
Therefore, an atom would be the simplest level of life, while the biosphere would be the most complex unit of life.
Hope this helps!

The correct answer is the Polychaos dubium, an Amoeboid.
The mapping of life's genome is an on-going process and probably won't end any time soon. This is arguably one of the largest genomes mapped however, at 670,000,000,000 base pairs, in comparison to the human genome, which is mapped at 3,200,000,000.
Protists are considered the most complex unicellular organisms. Algae as well as some parasites, such as the type that cause malaria, are classified as protists.
The brain is the most complex organ, and the human brain is the most complex of all animals.
Which organism is not limited by size because of its structures and life cycle?

sponges
Ants
The Siphonaptera has most complex excretory system, don't be fooled by it's size, it's a very complex organism!
it takes million of year to evolve in a organism coacervates<nitrates particle<nuetron particle<simple bacteria <complex bacteria<simple organism<complex organism
Organ systems are most complex and fragile starting with the atoms. The most complex organ systems is the organism. In between are the molecules, cell, tissue, organ, and organ system.
Flatworm
The Golgi complex is an organelle found in Eukaryotic cells. It is not an organism. Its job is to process and package macromolecules.
atoms and molecules --> cell --> tissue --> organ --> organ system --> organism
Humans are not the most complex organisms. Water fleas are the most complex organisms, containing 31,000 genes, about 25% more than the average human. Their body has enough genes to transform itself based on the environment it's in.
nerve chord
A+ bacteria.

Organism.
The correct answer is (from least to most complex) atoms, molecules, cells, tissues, organs, organ systems.
A complex organism is classified as an organism that has multiple cells with each having its own function. Examples of complex organisms are plants, humans, and animals.
an organism because an organism can contain multiple organ systems
It is the most complex type of mollusks.
Development is the process of change that produces a more complex organism. Classification is the process of organism based on similarities.
