Human health and Disease Quiz-16
Dear Readers,
NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions.
About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus.
Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience.

Q3. Surgical removal of thymus of a new born shall result in the failure to produce
Solution
Surgical removal of thymus of a new born shall result in failure to produce T-lymphocyte. Thymus provides the micro-environment for the development and maturation of T-lymphocytes

Q4. Which of the following diseases is caused due to allergic reaction?
Solution
Most common allergen for asthma is house dust, pollen grains, smoke, etc. Asthma is characterized by narrowing and inflammation of bronchi, bronchiospasm and difficulty in breathing

Q5.Acquired immunity is due to
Solution
The resistance that an individual acquires during life is called acquried immunity. Two major group of cells, i.e., lymphocytes (B and T-lymphocytes) and antigen presenting cells are involved in acquried immunity.

Q6. In India, AIDS was reported in
Solution
AIDS was first reported in USA in 1981. In India, first case of AIDS was detected in Chennai in 1986, AIDS (Acquired Immune Deficiency Syndrome) is caused by Immuno deficiency Virus (HIV).

Q7.During an allergic reaction, the binding of antigens to IgE antibodies initiates a response, in which chemicals cause the dilation of blood vessels and a host of other physiological changes. Such chemicals are
Solution
Histamine is released from mast cells during allergic reactions. Histamine can occur in various tissues but is concentrated in connective tissue. It is formed from the amino acids histidine . It causes dilation and increases permeability of small blood vessels, which results in such symptoms as localised swelling, itching, sneezing and runny eyes and nose.

Q8.The cancer of the epithelial cells is called
Solution
The cancer of epithelial cells is called carcinoma. It is a tumour that arises in the tissue that line the body’s organ like the nose, the colon, the penis, breast, etc. About 80% of all cancers are carcinomas. Leukaemia are cancers of blood or blood terming organ. Sarcoma originates in mesodermal tissue like bone, connective tissue muscle, cartilage, fibrous tissue or fat.

Q9.How does antigen-determinant differ from antigen binding site?
Solution
Antigenic determinants or epitopes are those sites on antigens, which are recognized by antibodies and receptors present on T and B-cells. Each antigen determinant can stimulate the formation of a particular kind of antibody or cell. The antibody’s antigen binding sites are located on the variable portion of the antibody. These sites help antibodies to combine specifically with antigens in the manner of lock and key. Hence, antigen determinants differ from antigen binding sites by their location, function and structure also.
