Answer:
The Thymus is a unique gland which protects the body against autoimmunity when the immune system act against itself.Hence the Thymus plays a significant role the dual systems i.e.,the lymphatic system (body’s defensive mechanism) and the endocrine system
Explanation:
The Thymus is special gland located anteriorly to the chest directly behind the sternum and in between the lungs. Active until puberty and gradually shrinks to become fat after puberty.
Function: Prior to birth and during childhood thymus engage in producing and maturation of T-lymphocytes or T-cells a particular type of white blood cells which defence the body against infectious disease germs.Though the organ does not function throughout the life span but it plays a significant role protecting the body against autoimmunity refers to an immune system works against itself .Therefore the thymus plays a key role in lymphatic system and an endocrine system.
Secretion:Thymus secretes Thymosin a hormone it instigates the development of T-Cells ( disease resisting cells) Thymosin stimulates the development of T-Cells until a human attains its puberty.
At the age of 75 thymus becomes a fatty tissue.
This disease is classified as a latent disease.
<h3>Classification of diseases</h3>
Latent disease is a classification of disease whereby the infectious agent remains inert in the body of its host between episodes of recurrent diseases.
Examples of viral pathogens that causes latent diseases include:
- <em>Herpes simplex, </em>
- <em>Varicella zoster, </em>
- <em>Human cytomegalovirus, </em>
- Adenovirus, and Kaposi's sarcoma.
The infection caused by the listed viral pathogens exhibit a latent disease phase whereby there is no noticeable symptoms of infection.

The time period was called the Hadean Eon, and the rocks themselves are nearly 4.4 billion years old
The correct statements are:
1. The atmosphere interacts with the hydrosphere to redistribute water over the surface of the Earth;
2. The atmosphere interacts with several Earth spheres, including the lithosphere;
3. Wind from the atmosphere creates ocean waves and currents;
The atmosphere is one of the few spheres, and it is of crucial importance for the life on our planet, but also for the shape of the world, and redistribution of temperature. Any slight change in it affects the whole planet significantly, and that just proves its importance. It can be a blessing, and it can be a curse with its activity, but whichever way it is, it is part of the natural process of our planet.
Answer:
The preferable option will be - D.
D. CNS and PNS
Explanation:
Multiple Sclerosis is a demyelinating disease affecting axons in the <u>CNS </u>nervous system, in contrast to Guillain Barre Syndrome, which strips the myelin sheath from axons in the <u>PNS</u> nervous system.
- Multiple sclerosis is an inflammatory disease in which our own immune system attacks our own nerve tissues and damages the central nervous system (brain and spinal cord).
- Guillain-Barre syndrome is an autoimmune disease in which our peripheral nervous system (PNS) gets affected.
