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.
Answer:FALSE:
Explanation:Out of all the rocky planets, Mercury is NOT the one humans are most likely to colonize.

<em>Answer:</em>
<em>T cells ( The thymus cells) and B cells ( The bone marrow) are the major cellular components of the adaptive immune response . T cells are involved in cell- mediated immunity , whereas B cells are primarily responsible for humoral immunity </em>
<em>Explanation:</em>
<em>Your body can produce the most effective weapons that are against the invaders, which may be bacteria, viruses or parasites. Other types of T-cells recognise and kill virus-infected cells directly. Some help B-cells to make antibodies, which circulate and bind to antigens. A T-cell (orange) killing a cancer cell (mauve).</em>
