The answer is NOT Widal test. The correct answer is blood culture.
Explanation: Widal test detects antibodies to typhoid bacilli, and not the bacilli itself. To detect the bacilli we must grow them on a simple nutritive media having pH 6 to 8, at temperature 37 deg C.
This answer is derived from Biology textbook by the Board(pg 130, below green box).
This is a tricky question. If students want to succeed at MHT-CET exam, they should practice a lot of such tricky questions. Commonly, students practice only simple questions which really have no value in competition. Every Tom, Dick and Harry knows those answers. If you want to beat them you should practice such questions.
Successful students do not read different books. They read the same books, but in a different manner.
Many question asked in actual MHT-CET Biology paper are tricky. As a matter of fact, most of the students score less than expected marks in Biology. Students who expect 90 marks in Biology usually score only 75 to 80 marks. Those who have already appeared for MHT-CET will know this by their own experience. If you are appearing for MHT-CET for the first time, you can ask your senior batch students about their experience.
Physics is difficult, hence students expect less marks and they score less marks. In Biology, they expect great marks, but score much lower then their expectation. This itself tells that special attention must be given to Biology. Also, not many students know that students with higher marks in Biology can get higher rank in MHT-CET.
The study material given by most of the coaching classes, MCQ practice books,etc. consists of simple questions only. They pickup single lines from the textbook and give it as a MCQ. Even a 10 yrs old kid can answer such simple MCQs. There is no competitive value in such questions.
Our test-series has been created with a special focus on such tricky, challenging and complex questions. We see to it that our students get complex questions to solve so that they can develop their skills and differentiate themselves from Tom, Dick and Harry. We know that merely giving simple questions to our students will not make they successful. In order to be successful, they need more than simple questions. The complex and tricky questions are created by Prof. Rohan Shenoy himself, and hence you will not find these questions in any other practice book or coaching classes’ study material.
