Getting a seat at 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 60 questions (40 MCQs + 20 A&R questions) from each Physics, Chemistry, and Biology along with 10 MCQs on Aptitude & Logical thinking and 10 from General Knowledge.
The biology Assertion and Reason section is a trickier one, as it is difficult to come up with the correct choice. Assertion and Reason are two statements that 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 Practice of this section can save you from such a dreadful situation.
To help you master Assertion & Reason type questions for the 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 the 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!
ASSERTION : Insulin chain B and C are produced separately in E.coli and then combined by disulphide bonds. REASON : Insulin chain A is not present in the mature insulin.
ASSERTION : Agrobacterium tumefaciens is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops. REASON : A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated.
ASSERTION : Intraspecific competition is always more acute than interspecific one. REASON : Intraspecific competition controls the size of population.
ASSERTION : Lichens and mosses are said to form the pioneer community in xerarch succession. REASON : Other species get established later, during the course of succession.
ASSERTION : Presence of large amounts of nutrients in water body causes excessive growth of planktonic algae. REASON : Presence of nutrient in water body is due to biomagnification.
ASSERTION : Presence of pneumatophores is a special adaptation of hydrophytes. REASON : Pneumatophores are positively geotropic shoots that have lenticels and help in gaseous exchange.
ASSERTION : In angiosperms the conduction of water is more efficient because their xylem has vessels. REASON : Conduction of water by vessel elements is an active process with energy supplied by xylem parenchyma rich in mitochondria.
ASSERTION : Blood in cockroach is colourless haemolymph with no respiratory pigment. REASON : Respiration in cockroach occurs through diffusion in haemolymph.
ASSERTION : Enzymes lower the activation energy. REASON : A substrate molecule can be acted upon by a particular enzyme.
ASSERTION : In mitosis each replication cycle of DNA is followed by one cell division. REASON : In meiosis one replication cycle of DNA is followed by two divisions.
