None of the above but present below epithelial cells
All epithelia are separated from their underlying tissues by an extracellular basement membrane which is fibrous in nature. The basement membrane is the fusion of two lamina namely, the basal lamina and the reticular lamina. The lamina reticularis is attached to the basal lamina with collagen anchoring fibrils and fibrillin microfibrils. The two layers together are collectively referred to as the basement membrane.

Division of the nucleus is called ..........
-
Cytokinesis
-
Karyokinesis
-
Replication
-
None of the above
Division of the nucleus is called karyokinesis. The process of partition of a cell's nucleus into the daughter cells during cell division is called karyokinesis. All the changes in a nucleus that occur during cell division are collectively termed as karyokinesis. It has four stages prophase, metaphase, anaphase, and telophase.
All nuclear changes that occur during mitotic cell division are collectively called as
-
Karyokinesis
-
Cytokinesis
-
Recombination
-
Both A and B
All nuclear changes (Prophase, metaphase, anaphase, and telophase) that occurs during mitotic cell division are collectively called as karyokinesis. Mitotic cell division consists of two steps. The first step is karyokinesis where nuclear division takes place which is followed by cytokinesis i.e the division of cytoplasm takes place and individual daughter cells are formed. So, the correct answer is 'Karyokinesis'.
The epithelial cells lining the stomach of vertebrates are protected from damage by HCl because.
-
HCl is too dilute
-
The epithelial cells are resistant to the action of HCl
-
HCl is neutralized in the stomach
-
The epithelial cells are covered by mucus
