The goal of sustainable agriculture is to ensure adequate food production, while also protecting the environment by minimizing the use of non-renewable resources.
true or false

The right answer is True.

Sustainable agriculture is the application to agriculture of the principles of sustainable or sustainable development as recognized by the international community in Rio de Janeiro in June 1992. It is a system of agricultural production that aims to ensure sustainable production of food, wood and fiber respecting the ecological, economic and social limits that ensure the maintenance over time of this production.

Sustainable agriculture aims to reduce the environmental impact of the sector. It is in particular an agriculture that better protects the biodiversity, the water and the soils that are necessary for it and which uses it better through the auxiliaries of agriculture and the ecosystem services.  And also by creating more per capita wealth per unit of production, on a more equitable basis. These principles are based on the recognition that natural resources are not infinite and that they must be used wisely to ensure long-term economic profitability, social well-being, and respect for the environment (all three are pillars of sustainable development).

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
