Remember that weight is calculated as mass * gravity
Explanation:
Weight is the result of the influence of gravity on the mass of an object. Therefore, differences in gravity will cause an object of the same mass to weight differently on a scale. On the moon, an astronaut would weight 1/3 of their weight on earth. This is because the gravity on the moon is approximately 1/3 that on earth. The influence of gravity is also higher the larger the mass of an object.

Correct me if I am wrong but I believe it’s option 1 and 2
The correct answer is option (A) trichomes.
Trichomes are the fine extensions from the epidermal surfaces covering the plant body. They are the result of epidermal cell division. They can be unicellular, multicellular and even glandular. They are characteristically present on the epidermal surfaces of leaves and roots. They reflect the solar radiation and help in mainitaining the internal temperature and reducing water loss. In roots, they absorb water and minerals and in leaves, they reduce water loss, lower the plant temperature. Plants may use trichomes to detect herbivore attacks as a defense mechanism.
While studying bases in the DNA of organisms, Chargaff discovered that the ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.
