Prokaryotic and eukaryotic cells have many differences but they also share some common features which of the following may be found in either type of cells

1. Ribosomes

2. DNA

3. Cytoplasm

4. Cell membrane

Explanation:

Prokaryotic and eukaryotic cells possess important differences but also share some similarities. The main difference between these types of cells is that eukaryotes contain membrane-bound organelles and a nucleus. Moreover, eukaryotic cells, in contrast to prokaryotic cells, contain a cell wall and chloroplasts (in plants) and mitochondria, Golgi apparatus, amongst other differences, including the genetic material which, in prokaryotic cells, is a single and circular DNA.

The similarities, on the other hand, involve, for example, the presence of ribosomes, vesicles, vacuoles, DNA, cytoplasm, and cell membrane. Although there is a significant difference in size and arrangement, we could say they share the similarity of possessing these structures.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
