They are anucleate cells.
Note that only mammals have anucleate red blood cells.
No, reticulocytes do not have a nucleus. They are immature red blood cells that still contain some residual RNA when released from the bone marrow. As they mature into erythrocytes (mature red blood cells), the nucleus is extruded.
No. As part of the RBC maturation process in mammals, the red blood cells loses its nucleus and is no longer able to synthesize RNA. Immature RBC's, called reticulocytes, do still have small amounts of RNA. However, it is atypical to see more then 1% in a healthy blood smear.
No, reticulocytes are immature red blood cells that have expelled their nucleus during development. This loss of the nucleus allows more space for hemoglobin, enabling the cell to efficiently transport oxygen.
An akaryotic cell is a type of cell that lacks a nucleus and other membrane-bound organelles. This term is often used to describe certain types of cells, such as red blood cells in mammals, which lose their nucleus during maturation to maximize space for hemoglobin. Akaryotic cells can also refer to some prokaryotic cells, which do not have a defined nucleus. These cells still carry genetic material, but it is not enclosed within a membrane.
A Animal Cell is both a Eukaryotic and Prokaryotic Cell. The Blood cells have no nucleus so they are considered Prokaryotic. That is also why they cannot divide and they do not live very long. The other cells are all Eukaryotic.Added:The above is totally wrong. Red blood cells may have no nucleus, as they mature to not have one, but they are still eukaryotic cells and all animal cells are eukaryotic.

NRBCs (nucleated red blood cells) are immature red blood cells that still contain a nucleus, typically seen in the blood of infants or in certain medical conditions. Reticulocytes are also immature red blood cells, but they have lost their nucleus. Reticulocytes are released from the bone marrow into the bloodstream to eventually mature into erythrocytes (mature red blood cells).
It is still blood, just without platelets. It still contains the red blood cells and plasma, which are valuable for use even without the clotting factors. Plasma without clotting factors is serum.

Not all cells have a nucleus. Also nuclei is plural many cells only have one nucleus. Generally cells that have a nucleus have DNA in it. It is suspected that originally the nucleus of cells had RNA instead of DNA and it is suspected that some cells still have RNA in their nucleus. A number of viruses use RNA instead of DNA.

No, white blood cells are not eukaryotes.Eukaryotes are organisms that have eukaryotic cells. People are eukaryotes, with many millions of eukaryotic cells.White blood cells are eukaryotic cells in eukaryotes.
A cell without a nucleus is called a prokaryotic cell, such as bacteria. While it lacks a nucleus, it still contains other cellular components necessary for its function, so it is still considered a cell.
No they don't. Eukaryotic cells are the ones that contain a nucleus. However, just because prokaryote cells don't contain a nucleus, they still contain DNA. It just floats freely in the cytoplasm.
No, kidney cells are eukaryotic.All cells in the human body are eukaryotic except one. Red blood cells are, strictly speaking, prokaryotic because they do not have a nucleus but this is a structural adaptation that allows the cells to carry as much oxygen as possible so they are still listed as eukaryotic.
A human blood smear comprises eukaryotic cells, as human cells are eukaryotic in nature. Eukaryotic cells have membrane-bound organelles, a nucleus containing genetic material, and are more complex compared to prokaryotic cells.
