In apiculture, the 'Apis mellifera' is preferred over the indigenous 'Apis cerana indica' primarily because:
A. It requires less floral nectar to produce honey
B. It has a higher honey collection capacity and stays in the hive for longer periods
C. It is more aggressive and defends the hive better
D. It does not sting
Answer: Option B
Solution (By JKExamLibrary)
Apis mellifera (the Italian or European honeybee) is widely preferred in commercial apiculture over the indigenous Apis cerana indica because it has a significantly higher honey collection capacity, yields more honey per hive, has a higher reproduction rate, and tends to stay in the hive for longer periods without swarming (absconding). While it can be more aggressive, its superior productivity makes it the choice for commercial beekeeping.
Explanation:
Translation is the process where the genetic code carried by mRNA is decoded to synthesize a specific sequence of amino acids, forming a protein. This process occurs at the ribosomes in the cytoplasm. Ribosomes read the mRNA codons and match them with the anticodons of tRNA molecules carrying the corresponding amino acids.
Explanation:
Anabaena azollae is a heterocystous cyanobacterium that lives symbiotically in the dorsal leaf cavities of the water fern Azolla. It fixes atmospheric nitrogen, providing a natural nitrogen source for rice paddies when Azolla is used as green manure. Nostoc is free-living or lichen symbiont, Rhizobium and Azotobacter are bacteria.
Explanation:
Fossils are direct evidence showing transitional forms. Lamarck proposed use and disuse, not natural selection. Analogous organs do not indicate common ancestry; homologous do. Appendix is vestigial.
