The country’s most prestigious medical entrance exam – AIIMS MBBS is scheduled to take place on 25th & 26th MAY 2019. Getting a seat into AIIMS college is a dream-come-true for every aspiring medical student. This exam not only tests your conceptual understanding of Physics, Chemistry and Biology with its variety of questions (MCQs+ A&R), but also examines your awareness regarding current affairs. AIIMS MBBS 2019 exam will consist of 200 objective type questions. This includes of 60 questions (40 MCQ’s + 20 A&R questions) from each Physics, Chemistry and Biology along with 10 MCQ’s on Aptitude & Logical thinking and 10 from General Knowledge.
Biology Assertion and Reason section is a trickier one, as it is difficult to come up to the correct choice. Assertion and Reason are two statements which may or may not hold any relation to each other and can be correct or incorrect. It is taxing to understand whether the two statements are related and the reason gives the correct explanation of the assertion or not. Any wrong response consumes your hard-earned points from the MCQS part. But, a GOOD Practise of this section can save you from such dreadful situation.
To help you master Assertion & Reason type questions for AIIMS exam, we are running quizzes from each subject viz, Physics, Chemistry and Biology. Here you can access an A&R Quiz of Biology, that offers you the most relevant questions with respect to AIIMS Biology 2019 exam. So, don’t hold back, participate in this quiz if you really want to get an MBBS seat in AIIMS college!
Let’s Start the Quiz!
1. ASSERTION : Mitochondria and chloroplasts have their own genome. REASON : Endoplasmic reticulum and Golgi body are the cell organelles which have their own DNA.
2. ASSERTION : The higher the turn-over number the more efficient an enzyme is. REASON : Turn-over number is not dependent upon the number of active sites present over an enzyme.
3. ASSERTION : Translocation of sugar from source (leaf) to sink is defined as pressure flow hypothesis. REASON : Translocation of the solute is facilitated through living phloem sieve tube cells.
4. ASSERTION : Glycolysis is the first step of respiration in which glucose completely breaks into CO2 and H2O. REASON : In glycolysis process, net gain of ATP is twenty four molecules.
5. ASSERTION : Trypsinogen is activated by enterokinase into active trypsin which in turn activates other enzymes in the pancreatic juice. REASON : The pancreatic juice contains inactive enzymes which are activated by intestinal juice.
6. ASSERTION : According to Haldane effect, binding of oxygen with haemoglobin tends to displace carbon dioxide from the blood. REASON : It is quantitatively far more important in promoting CO2 transport than the Bohr effect in promoting O2 transport.
7. ASSERTION : While on going down the loop of Henle, the filtrate becomes hypotonic. REASON : The descending limb of loop of Henle is impermeable to both water and electrolytes.
8. ASSERTION : On stimulation, a muscle cell releases calcium ions (Ca2+) from sarcoplasmic reticulum. REASON : By reacting with a protein complex, Ca2+ uncover active sites on the actin filaments.
9. ASSERTION : All copulations do not lead to the fertilisation and pregnancy. REASON : Fertilisation can occur only if the ovum and sperms are transported simultaneously to the ampullary – isthmic junction.
10. ASSERTION : Crossing over is important in evolution. REASON : Parts of homologous chromosomes are interchanged in crossing over.
