The brain is the body’s most complex organ. There are around 86 billion neurons in the human brain, all of which are in use. Each neuron communicates with many other neurons to form circuits and share information. Proper nervous system function involves coordinated action of neurons in many brain regions.

Q. What is the least complex organism?
In order, from least complex to most complex:
- cells.
- tissues.
- organs.
- organ systems.
- organism.
Q. What are 2 major types of cells?
Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
Q. What are 3 types of cells?
Cell Types
- Stem cells. Stem cells are cells that are yet to choose what they are going to become.
- Bone cells. There are at least three primary types of bone cell:
- Blood cells. There are three major types of blood cell:
- Muscle cells.
- Sperm cells.
- Female egg cell.
- Fat cells.
- Nerve cells.
Q. Does every human cell contain DNA?
Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Q. What are the only cells in the human body that don’t contain DNA?
Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA.
Q. What human cells do not contain DNA?
There is typically a lack of DNA in our mature red blood cells and cornified cells which are found in hair, skin, and our nails. These cells don’t contain a nucleus. It turns out, our red blood cells are actually trained to destroy their cells nuclei.
Q. Does saliva contain DNA?
Surprisingly, most people assume the source of DNA in saliva is strictly buccal epithelial cells. However, studies show that up to 74% of the DNA in saliva comes from white blood cells which are an excellent source of large amounts of high quality genomic DNA.
Q. Do plant cells have a nucleus?
Plant cell Plant cells have a cell wall and use organelles called chloroplasts to carry out photosynthesis. Like animal cells and other eukaryotic cells, plant cells have a nucleus that stores their DNA.
