So as the words speak for themselves, dependent variables are variables that aren't changed by outside factors unlike dependent variables which change based on an outside change. Knowing this, if you reread the problems you will be able to understand it a little bit more.
"When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside. "
The formation of the canyon provides a physical barrier that me lead to speciation between the two populations if interbreeding is prevented. The population to the west of the canyon will probably adapt to feeding on the berries on land, and might therefore evolve traits for a terrestrial, vegetarian existence. The turtles to the east of the canyon will evolve to take advantage of the river environment, and aquatic characteristics will be further emphasised.
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).
