Correct Answer: A. Edicts

Correct Answer: D. 30

Explanation

Molar mass of \(C_2H_4O_2\),= (12 × 2) + (1 × 4) + (16 × 2)= 60 g/mol

Vapour density = RMM/2

=60/2=30

Correct Answer: C. Mechanical weathering

Correct Answer: A. for emphasis

Correct Answer: D) Conjugation

Explanation

The question is asking about a form of sexual reproduction in Biology. Sexual reproduction refers to the process of producing offspring through the combination of genetic material from two different individuals. The options given are grafting, budding, fission, conjugation, and regeneration. Option A, grafting, is a type of asexual reproduction in plants where a part of one plant is attached to another plant to form a new plant. This is not a form of sexual reproduction. Option B, budding, is also a type of asexual reproduction in which a new individual develops as an outgrowth from the parent organism. This is not a form of sexual reproduction. Option C, fission, is a type of asexual reproduction in which the parent organism divides into two or more individuals of about the same size. This is also not a form of sexual reproduction. Option D, conjugation, is a type of sexual reproduction that occurs in some single-celled organisms such as bacteria and protozoa. It involves the transfer of genetic material between two individuals to form new offspring with a combination of genetic material from both parents. Option E, regeneration, is a type of asexual reproduction in which an organism can regrow a lost body part into a complete organism. This is not a form of sexual reproduction. Therefore, the correct answer is option D, conjugation. It is important to understand the different forms of reproduction in Biology, including sexual and asexual reproduction, and how they are different.
