The structure of DNA in eukaryotic cells resembles strands or filaments. DNA exists as chromosomes. Eukaryotic cells are significantly larger than prokaryotes and contain enclosed organelles within their cytoplasm, one of which is the nucleus.

What is the ratio of the volume of typical eukaryotic prokaryotic cells?
1000:1
What is animal cell?
Animal cells are refered to as eukaryotic cells. Eukaryotic cells are about 15 times wider than a typical prokaryote (plant cell) and can be as much as 1000 times greater in volume. The major difference between prokaryotes (plant cells) and eukaryotes is that eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place. Most important among these is a cell nucleus, a membrane-delineated compartment that houses the eukaryotic cell's DNA. This nucleus gives the eukaryote its name, which means "true nucleus."
Why are humans eukaryotes?
Eukaryotic cells are about 15 times wider than a typical prokaryote and can be as much as 1000 times greater in volume. The major difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place. Most important among these is acell nucleus, a membrane-delineated compartment that houses the eukaryotic cell's DNA. This nucleus gives the eukaryote its name, which means "true nucleus." Other differences include:The plasma membrane resembles that of prokaryotes in function, with minor differences in the setup. Cell walls may or may not be present.The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated withhistone proteins. All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. Some eukaryotic organelles such as mitochondria also contain some DNA.Many eukaryotic cells are ciliated with primary cilia. Primary cilia play important roles in chemosensation,mechanosensation, and thermosensation. Cilia may thus be "viewed as sensory cellular antennae that coordinate a large number of cellular signaling pathways, sometimes coupling the signaling to ciliary motility or alternatively to cell division and differentiation."[7]Eukaryotes can move using motile cilia or flagella. The flagella are more complex than those of prokaryotes.
How big are eukaryotic cells compared to prokaryotic cells?
Eukaryotic cells are much larger than prokaryotic cells. Most prokaryotic cells, such as bacteria, contain no nucleus, but instead has a nucleolus which contains its DNA structure. Eukaryotic cells, found in most plants and animals, are much larger in size and do contain a central nucleus, which holds its DNA.
Will water intake effect human blood volume?
For the short term and with reasonable amounts of water, ingested water will increase blood volume only transiently. However if there is kidney or cardiac problems or in cases where massive amounts of water is ingested the increase in volume plus the decrease in osmolarity of the blood is fatal.
Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom?
because of you
How does the volume of a nucleus to the volume of an atom?
the volume of atom is much greater than that of nucleus
How does the volume of a nucleus compare to the volume of an atom?
the volume of atom is much greater than that of nucleus
How does the structure of the nucleus relate to its function?
The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.

How do you calculate area from known volume and density?
You can't. A given volume can have very different amounts of area, depending on the shape.You can't. A given volume can have very different amounts of area, depending on the shape.You can't.

Is the most of the volume of an atom empty space or nucleus?
Most of the atom is empty space (between the electron orbitals and the nucleus itself). If your talking about nucleus vs. electrons then the nucleus is larger in volume and mass
Does the nucleus occupy most of the volume in the atom?
No it does not.

How much of an atom volume does the nucleus make up?

What are the 2 regions of the atom?
In general, the nucleus and the electron cloud are the two distinct features of the volume of the atom. The nucleus is home to the proton(s) and whatever neutrons are present, and the electron cloud is where the electrons all hang out. The nucleus, with its protons and neutrons, has most of an atom's mass concentrated there. The electrons are relatively far away, and the orbits they describe give the atom its "shape" by defining its volume in space.
