Nails and claws are not constituted by cells. Instead, they are proteins called keratin secreted produced by nearby cells. That is also the same protein used to make hair.
The nucleus is a highly specialized organelle that serves as the information and administrative center of the cell.
A bacterial cell has no nucleus. It is prokaryotic, meaning before nucleus, whereas a plant cell has a nucleus and is eukaryotic, meaning true nucleus. Also, plant cells are often specialized whereas bacterial never are.
No, organelles do not have a nucleus. Organelles are specialized subunits within a cell that perform specific functions, while the nucleus is a membrane-bound organelle that houses the cell's genetic material.
Usually, it's the nucleus. Usually. But in multicellular organisms can sometimes have have specialized cells with specialized organelles that can dwarf the nucleus. For example, adipocytes (aka fat cells) contain enormous vacuoles filled with lipids.
Many things such as... a nucleus and specialized organelles.

The only cell that I am aware of that does not contain a nucleus is the red blood cell. This cell rely's on specialized cells in the bone marrow in order to reproduce due to the fact that is is a brainless organism.
Yes, they have a seperate nucleus and specialized organelles, so animals cells are indeed eukaryotic.
The cell nucleus in an animal cell is a membrane-bound organelle that houses the cell's genetic material in the form of DNA. It controls the cell's activities by regulating gene expression and directing cellular functions. The nucleus also contains a nucleolus, where ribosomal RNA synthesis occurs.
A cell wall, chloroplasts, a nucleus, and a vacuole which is in a leaf cell and just to let you know the chloroplasts make the leaf green.
