Case Study Question for Class 10 Science Ch. 1 to 16
Case Study: 1
1) Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation. (CBSE Sample Paper 2022)
a.) What will be set of genes present in the F1 generation? (1 Mark)
Ans. Tt
b.) Give reason why only tall plants are observed in F1 progeny. (1 Mark)
Ans. Traits like ‘T’ are called dominant traits, while those that behave like ‘t’ are called recessive traits./Alternatively accept the definition of dominant and recessive traits with examples of T and t respectively /Alternatively accept the law of Dominance with examples of T and t.
c.) When F1 plants were self – pollinated, a total of 800 plants were produced.
How many of these would be tall, medium height or short plants? Give the genotype of F 2 generation. (2 Marks)
OR
When F1 plants were cross – pollinated with plants having tt genes, a total of 800 plants were produced. How many of these would be tall, medium height or short plants? Give the genotype of F 2 generation.
Ans. Out of 800 plants 600 plants will be tall and 200 plants will be small, 1
TT: 2Tt: 1tt (1 mark)
OR
In the cross between Tt X tt, 400 Tall (Tt) and 400 short (tt) plants will be produced.
1Tt:1tt
Case Study: 2 Question Class 10 Science
2) Ansari Sir was demonstrating an experiment in his class with the setup as shown in the figure below. (CBSE Sample Paper 2022)
A magnet is attached to a spring. The magnet can go in and out of the stationary coil.
He lifted the Magnet and released it to make it oscillate through the coil. Based on your understanding of the phenomenon, answer the following questions.
a.) What is the principle which Ansari Sir is trying to demonstrate?
Ans. Sir is trying to demonstrate the principle of Electromagnetic induction.
b.) What will be observed when the Magnet starts oscillating through the coil. Explain the reason behind this observation.
Ans. There will be induced current in the coil due to relative motion between the magnet and the coil. Changing the magnetic field around the coil generates induced current.
c.) Consider the situation where the Magnet goes in and out of the coil. State two changes which could be made to increase the deflection in the galvanometer.
OR
Is there any difference in the observations in the galvanometer when the Magnet swings in and then out of the stationary coil? Justify your answer.
Ans.
Using a stronger magnet, using a coil with more number of turns.
Or
When the magnet moves into the coil, the ammeter shows a momentary deflection towards one side say left.
When the magnet moves out of the coil, the ammeter shows a momentary deflection now towards right.
This is due to changing magnetic field /flux associated with the coil as the magnet moves in and out.
Alternatively, the flux increases when the magnet goes in and it decreases when the magnet goes out.

Key questions for 10th review science are outlined agreeing to the CBSE NCERT program. All address sorts are accessible within the PDF, from one-word to one-line answers, brief reply sorts to five point long reply sorts. Hence, understudies can plan for exams and indeed clarify their concepts through them. On the off chance that they refer to these questions, it’ll get ready their minds to pick up a competitive advantage. Understudies will gotten to be commonplace with question patterns and the sorts of questions that will show up on exams.
