The process by which two different organisms live together and both benefit is: MCQ with Answer and Explanation

Explanation:
Stomatal transpiration, which occurs through the stomata (pores) on the leaf epidermis, accounts for about 90% of the total water loss in plants. Cuticular transpiration occurs through the waxy cuticle and is minimal. Lenticular transpiration occurs through lenticels in woody stems and is also very small.

Explanation:
RNAi is a cellular defense mechanism in eukaryotes that silences specific mRNA. To create nematode-resistant tobacco, scientists used Agrobacterium as a vector to introduce nematode-specific genes into the host plant. The plant then produced both sense and anti-sense RNA for these genes. The double-stranded RNA (dsRNA) formed triggered the RNAi pathway, degrading the nematide's mRNA when it tried to express those essential genes inside the plant roots, killing the nematode.

Explanation:
Frogs belong to the class Amphibia, characterized by a life cycle that includes an aquatic larval stage (tadpole) with gills and an adult stage with lungs, moist skin, and a three-chambered heart. Turtle, snake, and lizard are reptiles, with dry scaly skin and amniotic eggs. Amphibians are the first terrestrial vertebrates but depend on water for reproduction.
