How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentences.Can someone please help me with this?

Answers

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Eventhough it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization

People could choose to practice organic farming, heirloom plants, or use GMOs.Governments could pass laws to limit the use of monoculture farming or require people to use alternate farming methods.

The water in a 150-mL flask is poured into a beaker that contains 600 mL of ethyl alcohol. Which substance is the solvent in this mixture?

Answers

Answer:

Ethyl alcohol is a solvent on the mixture.

Explanation:

Solution: It is a mixture of liquid in which solute (minor component) is distributed uniformly in a solvent (major component).

In a solution, mass of solute is always less than the mass of solvent.

Mass of water = 150 mL

Mass of ethyl alcohol = 600 mL

Mass of water < Mass of ethyl alcohol

Ethyl alcohol is a solvent on the mixture.
The solvent in the mixture is the ethyl alcohol assuming that the ethyl alcohol is not very dilute. The amount of the solvent must be greater than the amount of the solute. If the ethyl alcohol is dilute such that the resulting solution will have more water than pure ethyl alcohol, the solvent is water and the solute is ethyl alcohol.
