What does the nucleus do? The nucleus was discovered in 1911 by Ernest Rutherford, a physicist from New Zealand, according to theAmerican Institute of Physics. In 1920, Rutherford proposed the name proton for the positively charged particles of the atom. He also theorized that there was a neut...
The nucleus is an organelle that contains the genetic information for that organism. In an animal cell, the nucleus is located inthe central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell....
What neurotransmitter controls the somatic nervous system? What tissues does the somatic nervous system stimulate? What does the nucleus do in a neuron? How many neurons are in the somatic nervous system? Where are somatic motor neuron cell bodies located?
The protons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are held very loosely. They can move from one atom to another. An atom that loses electrons has more positive charges (protons) than negative charges...
If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...

What types of cells do Endostatins go after? What is the role of goblet cells in pseudostratified ciliated columnar epithelial tissue of the upper respiratory tract? Dipalmitoylphosphatidylcholine is secreted by what cells? What is the more complex cell type that has a membrane-enclosed nucleus and...
How do atoms make ions? Atoms aren't just packets of matter: they contain electrical energy too. Each proton in the nucleus of an atom has a tiny positive charge (electricity that stays in one place). We say it has a charge of +1 to make everything simple (in reality, a proton's...
Identify a single squamous cell and its nucleus. Which leukocyte(s) are classified as agranulocytes? What is chromatophilic substance? What are gyri? What is a sarcomere? How are its proteins organized? a. What is fibroblast? b. What does it produce?
And we could see that they didn’t have what we call a nucleus. So they got their own kingdom, a kingdom of very tiny things without nucleoli. So then we had several kingdoms for plants and for animals, and the different kinds of fungus like mushrooms, and for these tiny bacteria. ...
