Reason (R): Ciliary muscles control the power of the eye lens.
In the light of the above statements, choose the most appropriate answer from the options given below:
Show Hint
The ciliary muscles change the shape of the eye lens, allowing it to focus on objects at various distances. This is called accommodation.

- Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
- Both Assertion (A) and Reason (R) are true, and Reason (R) is not the correct explanation of Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false, but Reason (R) is true.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Assertion (A) is correct as contraction of ciliary muscles results in the lens becoming thinner. However, Reason (R) is incorrect. The ciliary muscles do not directly control the power of the lens; they alter the shape of the lens to focus on nearby or distant objects, thus adjusting its power.
Therefore, the correct answer is option (3).

- More than three million carbon compounds have been discovered in the field of chemistry. The diversity of these compounds is due to the capacity of carbon atoms for bonding with one another as well as with other atoms. Most of the carbon compounds are poor conductors of electricity and have low melting and boiling points.
- Human digestive system is a tube running from mouth to anus. Its main function is to breakdown complex molecules present in the food which cannot be absorbed as such into smaller molecules. These molecules are absorbed across the walls of the tube and the absorbed food reaches each and every cell of the body where it is utilised for obtaining energy.
- A student has three convex lenses A, B, and C of different focal lengths. He wants to observe the images formed by these lenses on a screen by placing a candle flame at different distances as given in the following table:
Case No. Lens Focal Length Object Distance 1 \(A\) 50 cm 25 cm 2 B 20 cm 60 cm 3 C 15 cm 30 cm - Consider the unbalanced chemical equations of the chemical reactions listed below:

- When a pure-tall pea plant is crossed with a pure-dwarf pea plant, the percentage of tall pea plants in F1 and F2 generation pea plants will be respectively:
- Which one of the following has half the number of chromosomes and half the amount of DNA as compared to the non-reproductive body cells?
Pure-tall (TT) pea plants are crossed with pure-dwarf (tt) pea plants. The pea plants obtained in F1 generation are then self-pollinated to produce F2 generation.
(i) What do the plants of F1 generation look like? Justify your answer.
(ii) What is the ratio of pure-tall plants to pure-dwarf plants in F2 generation?- What is regeneration? Give one example of an organism that shows this process and one organism that does not. Why does regeneration not occur in the latter?

Print Comes to India
From 1780, James Augustus Hickey began to edit the Bengal Gazette, a weekly maga zine that described itself as ‘a commercial paper open to all, but influenced by none’. So it was private English enterprise, proud of its independence from colonial influence, that began English printing in India. Hickey published a lot of advertisements, including those that related to the import and sale of slaves. But he also published a lot of gossip about the Company’s senior officials in India. Enraged by this, Governor-General War ren Hastings persecuted Hickey, and encouraged the publication of officially sanctioned newspapers that could counter the flow of information that damaged the image of the colonial government. By the close of the eighteenth century, a number of newspapers and journals appeared in print. There were Indians, too, who began to publish Indian news papers. The first to appear was the weekly Bengal Gazette, brought out by Gangadhar Bhattacharya, who was close to Raja Rammohan Roy. - Read the following source carefully and answer the questions that follow:
