Human health and Disease Quiz-20
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. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced.
.
Q1. Antibody
Solution
The B-lymphocytes (types of WBC) produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies

Q2. An example of innate immunity is
Solution
Innate immunity is inherited by the organisms from their parents and protects it from birth to throughout life. PMNL-neutrophils are example of innate immunity.

Q3. Smokeless tobacco causes
Solution
Chewing of tobacco causes oral cancer, which becomes fatal in extreme conditions
Chewing of tobacco causes oral cancer, which becomes fatal in extreme conditions
Q4. Smoking addiction is harmful because it produces polycyclic aromatic hydrocarbons, which cause
Solution
Polycyclic aromatic hydrocarbons are carcinogenic and thus, cause cancer.
Polycyclic aromatic hydrocarbons are carcinogenic and thus, cause cancer.
Q5.The primary and secondary immune responses are carried out with the help of
Solution
The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes. The B-lymphocytes produce an army of protein in response to pathogens into our blood to fight them. These proteins are called antibodies. Antibodies are protein molecules also called immunoglobins (lg)

Q6. Select the true statements
I. Cancer can be detected by the use of antibodies against cancer specific antigens for certain type of cancer
II. The tumour cells are surgically removed to reduce the load of cancerous cells
III. Certain chemotherapeutic drugs are used to kill the cancerous cells, but majority of the drugs have side affects like hair loss, anaemia, etc.
Solution
Monoclonal antibodies against cancer-specific antigens are also used for detection of certain cancer The tumour cells are removed with the help of surgery to check the spread of cancerous cells Cancerous cells are killed by several chemotherapeutic drugs. These drugs exhibit side effects like hair loss, anaemia. In immunotherapy, biological modifiers like α-interferons are used, which activate the immune system and help in destroying the tumour

Q7.The major phagocytic cells are
Solution
The major phagocytic cells are macrophages. Phagocytosis is the process of engulfing a solid particle by a phagocyte

Q8.Magic bullets are the
Solution
Monoclonal antibodies are highly specific antibodies derived from only one clone of a specific hybridoma cell. They recognize only one specific site of an antigen. These can be used in detecting allergies, diagnosing viral diseases and in detecting certain types of cancers. Monoclonal antibodies are now-a-days marketed as ‘magic bullets’ The idea of magic bullet was first proposed by Paul Ehrlich.

Q9.Which of the following diseases is not caused by virus?
Solution
Tuberculosis (TB) is caused by a rod-shaped bacterium named Mycobacterium tuberculosis. It commonly affects the lungs. The bacteria damage tissues and release a toxin named tuberculin
