What is the least complex body system?
In order, from least complex to most complex: cells. tissues. organs. organ systems.
Why are eukaryotic systems so complex as compared to bacteria or prokaryotes?
The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it’s a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.
What is the correct order from least complex to most complex?

What diseases can the cytoskeleton cause?
Indeed, many diseases have now been associated with abnormalities in cytoskeletal and nucleoskeletal proteins, including several cardiovascular disease syndromes, neurodegeneration, cancer (invasion), liver cirrhosis, pulmonary fibrosis, and blistering skin diseases.
How does cytoskeleton affect the body?
The cytoskeleton can be compared to a transport network facilitating various types of movement in the cell. It helps with cell reproduction, the movement of organelles, the functions of muscles and intracellular transport between the organelles.
What disease affects the nerves?
Disorders of the nervous system Structural disorders, such as brain or spinal cord injury, Bell’s palsy, cervical spondylosis, carpal tunnel syndrome, brain or spinal cord tumors, peripheral neuropathy, and Guillain-Barré syndrome. Functional disorders, such as headache, epilepsy, dizziness, and neuralgia.
What is the most common neurodegenerative disorder?
Alzheimer’s disease and Parkinson’s disease are the most common neurodegenerative diseases. In 2016, an estimated 5.4 million Americans were living with Alzheimer’s disease. An estimated 930,000 people in the United States could be living with Parkinson’s disease by 2020.
How can you prevent neurodegeneration?
Examples of lifestyle choices that can help to reduce the risk of neurodegenerative disease include regular physical activity, a healthy diet, intake of certain dietary supplements, adequate sleep, and engaging in cognitive activity.
