| Re: TIFR Biology Question Papers
The test will be extremely basic and cover topics in mathematics, physics, chemistry and biology. Here I’m providing you few questions of TIFR Biology: 1. Migrating birds often fly in a V-shaped formation. Why? a. To increase their visual range to aid navigation b. To deter predatory birds c. So that related individuals can fly together d. To conserve energy due to aerodynamic effects 2. Elephants sometimes use infrasound in the 5 –20 Hz range to communicate, rather than sounds in the human audible range of 20 – 20,000 Hz. This is probably because a. The large elephant ear cannot detect high frequencies b. There is too much competing sound in the 20 – 20,000 Hz range c. Infrasound has a longer distance range than higher frequency sound d. This keeps elephant herds hidden from predators 3. People with anaemia are most likely to be comfortable in a. Leh b. Lhasa c. Lucknow d. La Paz, Bolivia 4. Fifty rabbits from an isolated forest patch were captured, marked with special tags, and released. The next day, sixty rabbits were captured and ten of these were found to have tags. What assumptions do you need to make to estimate the number of rabbits in the forest from these data? a. All rabbits are equally likely to get captured b. The number of rabbits in the forest is very high c. All captured rabbits are approximately the same age and healthy d. Rabbits are equally active at all times of day 5. A medical test for some condition has a false positive rate of 0.1% and false negative rate of 0.1%. The condition is present in 0.1% of the population. What is the probability that a randomly tested individual who tests positive actually has the disease? a. 0.1 b. 0.5 c. 0.9 d. 0.999 TIFR Biology Question paper 2010  Here I’m attaching PDF format of question paper of TIFR biology: |
