Red blood cells have no nucleus. This allows them more space to carry oxygen.
I think you need to rephrase your question. A human cell IS an animal cell. Humans are animals. And yes, nuclei are found within animal cells, human are otherwise.
Yes, human body cells are eukaryotic and contain nuclei. The nucleus contains the cell's genetic material, which is organized into chromosomes and responsible for regulating cell activities like growth, metabolism, and reproduction.
A cell would die without its nucleus as it is its "brain" which controls the cell. Only human red blood cells have no nuclei after maturity.
It does not consist of nuclei
A cow's red blood cell does not have a nuclei. Most mammals do not have a nuclei in their red blood cells.
Fish blood contains nuclei in each blood cell and are much larger than human blood.
a nuclei a cytoplasem and cell membrane
In cell biology, nuclei refers to the plural form of nucleus. The nucleus is a membrane-bound organelle that contains the cell's genetic material, while nuclei are multiple nuclei found in a cell, such as in muscle cells or certain types of fungi.
cells come from other cells
The human sperm cell has 23 chromosomes. White blood cells have 46 chromosomes. Mature red blood cells to not contain a nucleus, and therefore has no chromosomes. Platelets are cell fragments and also do not contain nuclei.
there are binucleated cells in the liver and in the transitional epithelium of the urinary bladder
Broadly speaking, yes. It should be pointed out, however, that mature red blood cells are somatic cells which contain no chromosomes at all. Also, osteoclasts are somatic cells which contain multiple nuclei and thus multiple pairs of homologous chromosomes (although they only have 23 homologous chromosomes in any given nucleus).
