What is the purpose of hardening?
To eliminate all disease
To manage the population of endangered trees
To allow nursery plants to transition to the outdoors
To make sure that the trunk of the tree is as strong as possible before planting
Answer: To allow nursery plants to transition to the outdoors.
Explanation:
Hardening is a process in which the small seedling plants are exposed to the unprotected environment of the garden so that they develop some tolerance against those conditions. The small seedlings were earlier exposed to low water, sunlight, and wind conditions but for hardening they are kept at those areas of the garden where they experience harsh levels of these agents for a short duration and the duration is increased with routine so that plants can adapt the changes when they are planted outdoor or outside the care of garden. It is one of the gardening practices.

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight
A Spray irrigation
Furrow irrigation
Flood irrigation
Drip Irrigation
Answer: Furrow Irrigation (B)
Explanation:
Furrow irrigation
Salinization of the SoilThe accumulation of water-soluble salts in the soil is known as salinization. Excess salts inhibit crop growth by decreasing their ability to absorb water, making salinization a resource concern.Surface irrigation in which trenches or "furrows" are created between crop rows in a field is known as furrow irrigation. Furrow irrigation is done by laying down short parallel channels down the length of the field in the direction of the predominant slope.Furrow irrigation is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlightFor more information:

Utility companies use _ per month, to determine how much energy is being used.
What goes in the blank ?
Answer:
Kilowatt-hour
Explanation:
Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).
Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.
