What types of epithelial Cells secrete mucus?
Goblet cells are specialized epithelial cells that secrete mucus in various parts of the body such as the respiratory and digestive tracts. These cells are responsible for producing the protective mucus layer that helps lubricate and protect the epithelial surfaces.
How can mutation affect protein synthesis in cell?
Mutations can make the protein synthesise incorrectly making diseases or weak parts in your body. Mutations can affect protein synthesis in cells by affecting the protein, messing up the whole DNA sequence and making the organism different from other average organisms.
What are the three parts of a virion?
The three parts of a virion are the genetic material (DNA or RNA), the protein coat (capsid), and sometimes an outer lipid envelope. The genetic material contains the instructions for replicating the virus, the protein coat provides protection and facilitates attachment to host cells, and the envelope helps the virus enter host cells.
What is psuedostratified columnar epithelium?
Pseudostratified columnar epithelium is a type of epithelial tissue that appears to be stratified but is actually a single layer of cells. It contains different types of cells, such as ciliated cells and goblet cells, which perform various functions like moving mucus and facilitating absorption. This tissue is typically found lining the respiratory tract and parts of the reproductive system.
What is correct concerning a spherical cell?
A spherical cell is round in shape, which can provide structural stability and allows for efficient nutrient and waste exchange. The spherical shape also minimizes the surface area-to-volume ratio, which can help with optimizing cellular functions.
