Answer:
are there any sentences to choose from
Amoebas use extensions of their cell membrane (called pseudopodia) to move, as well as, to engulf food. When the pseudopodium traps a bit of food, the cell membrane closes around the meal. This encasement forms a food vacuole. Hope this helps.
The answer is C. Four genetically identical, diploid daughter cells.
Answer:
The correct answer is: Mucus membrane.
Explanation:
- The lining of the epithelial tissue forming the mucus membrane contains some specialised cells which are called the Goblet cells.
- These cells secrete a slippery substance called the Mucus.
- The Mucus is a dense, aqueous and slippery substance that is composed of anti-microbial enzymes like lysosyme, immunoglobulins (antibodies) and glycoproteins like mucins.
- The mucus secreting cells line the internal tracts of the body that come into contact with outside environment, like the respiratory tract, alimentary canal, urino-genital tract.
- If any microbial pathogen gain access into any of these tracts the lysosyme in the mucus causes the microbial cells to undergo lysis, hence killed.
- The immunoglobulins, on recognising a pathogen, activate the immune cells of the body to fight against the intruding pathogen.
