Human health and Disease Quiz-11
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.

Q4. Which among the following is an autoimmune disease?
Solution
Rheumatoid Arthritis (RA) is a form of inflammatory arthritis and an auto-immune disease
Rheumatoid Arthritis (RA) is a form of inflammatory arthritis and an auto-immune disease
Q5.A person has developed interferon in his body. He seems to carry an infection of
Solution
Interferons block viral reproduction in healthy cells. Measles is caused by the measles virus. Typhoid is a bacterial disease. Filariasis is a parasite disease (usually an infectious tropical disease) that is caused by thread-like nematodes. Malaria is caused by a protozoan (Plasmodium sp.) but carried by the female Anopheles mosquito

Q6.

A-Gametocytes, B-Salivary glands, C-Sporozoites
A-Gametocytes, B-Salivary glands, C-Sporozoites
Q7.Malignant tumours are
I. mass of neoplastic cells
II. cells that grow very rapidly and damaging the surrounding normal tissue
III. cells that show the property of metastisis
Which of the statements given above are correct?
Solution
The malignant tumours, is a mass of proliferating cells called neoplastic or tumour cells. These cells grow very rapidly, invading and damaging the surrounding normal tissues. As these cells actively divide and grow, they also starve the normal cells by competing for vital nutrients. Cells sloughed from such tumours reach distant sites through blood, and wherever they get lodged in the body, they start a new tumour there. This property called metastasis is the most feared property of malignant tumours

Q8.Which one of the following is correct matching of a vitamin, its nature and its deficiency disease?
Solution
Fat soluble vitamins are A, D, E and K. Deficiency of vitamin-A leads to night blindness or nyctalopia because vitamin-A is essential for the synthesis of visual pigment, rhodopsin.

Q9.Metastasis is associated with
Solution
A single faulty cell may divide to form clone of identical cells forming an irregular mass called tumour. Tumour cells can break away and spread to other parts of the body particularly in the blood stream causing secondary tumour. This process is called metastasis. Tumour that spread and cause ill health and death are described as malignant.
