The two correct statements are

Question

Select the correctly written scientific name of Mango which was first described by Carolus Linnaeus:

Answer 1

Let's analyze each of the statements provided and determine which ones are correct based on established biological knowledge.

Statement A: "Definition of biological species was given by Ernst Mayr."
This statement is correct. Ernst Mayr, a renowned evolutionary biologist, defined the concept of biological species in terms of reproductive isolation. According to Mayr's Biological Species Concept, a species is a group of interbreeding natural populations that are reproductively isolated from other such groups.
Statement B: "Photoperiod does not affect reproduction in plants."
This statement is incorrect. Photoperiod, which refers to the length of day and night, significantly affects the reproductive cycles of many plants. It plays a crucial role in processes such as flowering, seed germination, and other phenological events.
Statement C: "Binomial nomenclature system was given by R.H. Whittaker."
This statement is incorrect. The binomial nomenclature system was developed by Carl Linnaeus, not R.H. Whittaker. Linnaeus is known for creating a systematic classification system based on the binomial nomenclature, which is the formal system of naming species.
Statement D: "In unicellular organisms, reproduction is synonymous with growth."
This statement is correct. In unicellular organisms, reproduction and growth are synonymous because a single cell divides to form two new cells. This division is essentially both growth (increase in number) and a form of asexual reproduction.

Based on the analysis above, the two correct statements are A and D. Hence, the correct answer is: A and D.
