BIOLOGY HEALTH AND DISEASES QUIZ-9
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. Large group of lymphoid tissue in respiratory, digestive and urogenital tract are collectively called
Solution
(a) There is lymphoid tissue also located within the lining of the major tracts (respiratory, digestive and urogentital tracts) called Mucosa Associated Lymphoid Tissue (MALT). It constitutes about 50% of the lymphoid tissue in human body

Q2.X-rays are used in
Solution
(c) X-rays are used in CT-scan (computed tomographic scanning). It uses X-rays but employs a computer for reconstructing the image instead of directly recording it on a photographic film.

Q3. Tumour viruses or cancer causing viruses called …A… have …B… . Here A and B refers to
Solution
(b) Tumour viruses or cancer causing viruses called oncogenic viruses, have viral oncogenes
(b) Tumour viruses or cancer causing viruses called oncogenic viruses, have viral oncogenes
Q4. What is true about T-lymphocytes is mammals?
Solution
(c) The function of T-cells is to provide immunity (cellular type) and not to scavenge damaged cells and cells and cell debris. These are produced in bone marrow and mature in thymus. Hence, the only true statement is that there are three types of T-cells, i.e.,cytotoxic, helper and suppressor.

Q5.Plasmodium life cycle is
Solution
(a) Plasmodium life cycle is digenetic. Plasmodium completes its life cycle in two hosts (digenetic). i.e., man and female Anopheles mosquito

Q6. Damage to thymus in a child may lead to
Solution
(a) Thymus is the “seedbed” of thymic lymphocytes (T-lymphocytes). Some stem cells in the bone marrow give rise to immature lymphocytes. These lymphocytes migrate via the blood to the thymus, where they mature as T-lymphocytes, and produce cell-mediated immunity. Thus, damage to thymus in a child may lead to loss of cell-mediated immunity.

Q7.Triple antigen vaccine is not used for
Solution
(a) Disease like whooping cough (pertussis), diphtheria and tetanus (lock jaw) can be prevented by immunizing all infants with triple vaccine-DTP (i.e.,diphtheria, pertussis, tetanus vaccine). Typhoid, caused by bacterium Salmonella typhi, cannot be cure with triple vaccine but typhoid did vaccine is available.

Q8.Which technique uses the body’s water molecules as the bases for its images?
Solution
(b) In MRI, the body’s water molecules are used for the base of images.

Q9.Immunoglobulins are made up of
Solution
(b) Immunoglobulins are present in serum and provide immunity to body against diseases. Each immunoglobulin is made up of four polypeptide chains-two heavy weight chains and two light weight chains. These chains are joined to each other by disulphide bonds.

Q10. Which one of the following diseases is caused by virus?
Solution
(c) Measles is a viral disease while diphtheria, cholera and whooping cough are bacterial diseases.
