Which of the following lists goes from least complex to most complex?
List the following in order from least complex to most complex: organ, cell, tissue, and organ system.
Which cell type is the least complex?
Prokaryotes and eukaryotes constitute two of the three domains of life (the third domain is archaea). Generally speaking, prokaryotic cells are smaller and less complex, whereas eukaryotic organisms are larger and can even be multicellular.
Which list represents a systems from the least to most complex?
In resume, the levels are: chemical, cellular, tissue, organ and organismal. From least to most complex.
Did all of the least complex organisms die off?
It’s generally thought that the evolution of complex life was a rare, once-in-4.5-billion-years event. But new research suggests that conditions were right for complex cells to evolve and die off at least once – or perhaps several times – before our lineage even got started.
Are atoms less complex than cells?
Molecules are made up of atoms, which are the least complex components on the list. A cell has many different molecules in it, and an organ is an organized structure made up of many cells. As complexity increases, novel properties emerge at each level that are absent from the preceding level.
What is the most complex level?

Which is the most complex level of body organization?
organismal level
The most complex level of organization is the organismal level, where all eleven organ systems function in the human organism, the whole living person.
What is the most complex level of organization?
How long does it take for complex life to develop?
4 billion years
After simple cells first appeared, there was an extraordinarily long hiatus – nearly half the lifetime of the planet – before complex ones evolved. In fact, it appears that simple cells gave rise to complex ones just once in 4 billion years of evolution, which is suggestive of a freak accident.
What caused life to become more complex?
Some possibilities include: The evolution of predators with skeletons in the Cambrian. Competition from more advanced Cambrian organisms. Changes in environmental conditions caused by supercontinent breakups such as rising sea level, limited nutrients, or changing atmospheric and oceanic chemistry.
Which is the smallest and largest cell in human body?
The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.
What is the most complex system in the human body?
The brain
The brain is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around 1.4 kilograms, contains a staggering one hundred billion nerve cells, or neurons.
Is human DNA the most complex?
Sequencing One of the Most Complex Genomes Known to Science. By comparison, the human genome is about five times smaller, with about three billion base pairs and two copies of 23 chromosomes. Previously published versions of the bread wheat genome have contained large gaps in its highly repetitive DNA sequence.
