Answer:
Nitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N2) to ammonia (NH3) in a process called nitrogen fixation.
Answer:
All of the listed responses are correct.
Explanation:
Ecotourism is the approach to allow humans to visit the natural habitats of flora and fauna without harming these natural resources in one or other ways. Some places/countries are specifically rich in natural habitats of species diversity and endemism. These habitats are mostly being destroyed by human activities.
These natural habitats of high endemism and habitat destruction are called biodiversity hotspots. These regions present in various countries should be protected to slow down the current loss of biodiversity. Non-native species mostly harm the native species. In absence of any competitors or natural predators, these non-native species flourish well in new habitats and deprive the native ones of resources.

I would say A because you don’t really need any achievements to take charge of your behavior and learn. You do need motivation to work hard though.
There is confusion over the definition of the term “viability state(s)” of microorganisms. “Viability staining” or “vital staining techniques” are used to distinguish live from dead bacteria. These stainings, first established on planctonic bacteria, may have serious shortcomings when applied to multispecies biofilms. Results of staining techniques should be compared with appropriate microbiological data.
