what are the function of root nodules?what are tge adverse effect of global warming? |

Answer» root nodulesoccur on therootsof plants (primarily Fabaceae) that associate with symbiotic nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. Theeffects ofglobal warmingare the environmental and social changes caused (directly or indirectly) by human emissions ofgreenhouse gases. There isa scientific consensus that climate change is occurring, and that human activities are the primary driver.Many impacts of climate change have already been observed, includingglacier retreat,changes in the timing of seasonal events(e.g., earlier flowering of plants),and changes in agricultural productivity.Anthropogenic forcing has likely contributed to some of the observed changes, includingsea level rise, changes in climateextremes,declines in Arctic sea iceextent and glacier retreat. |
