Answer:
A. a lamp being turned on
B. a toaster being used to toast bread
D. a car horn honking
Explanation:
Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.
From the examples given in this question, the following are examples of scenarios that involve energy transformation:
- A lamp being turned on: This converts chemical energy to light energy.
- A toaster being used to toast bread: This converts electrical energy to heat energy.
- A car horn honking: This converts electrical energy to sound energy.
Note that, melting of a chocolate does not transform any form of energy.
Like all life on earth, plants need water to survive and grow. Indeed, like humans, water is the primary element that makes up the structure of plants. Human bodies are comprised of around 70 percent water, but in plants this proportion can be as much as 95 percent. Water is also essential to the way a plant receives nutrients and provides energy for itself. Thus, water is arguably the most essential substance required by plants. That is why many elements of permaculture design – from using swales and contouring to slow runoff from the land and allowing it to sink into the soil to mulching to prevent evaporation of moisture from the soil surface – emphasis the preservation of water so that it can be provided to plants.

Answer:
pesticides are in the form of insecticides,fungicides,herbicides plant growth regulators and so on
Explanation:
Pesticides are lethal to target pests but not to the non-target pests it includes humans as well. The application of pesticides brings gain to the farmers by getting higher yields for better and protected crops. Insecticides act against insects growth, herbicides protects herbs, weeds from its pests, rodenticides protects from rats,avicides protects birds fungicides act against fungi and nematicides act against nematodes. Pesticides are divided according to their types.To protect some plant and animals population which can withstand with pesticides environment.
Answer/Explanation:
Chilli and Beans are two different groups of crops having different nutrient requirement for them to grow well.
Beans is a leguminous crop that can help fix nitrogen back to the soil after the soil nitrogen content has been depleted by crops that use up nitrogen in the soil.
So, one of the possible reasons why Sangay plants Chilli the first, and beans the next year could be to ensure optimal productivity, as beans would replenish the soil with nitrogen. Also, both crops have different nutrient requirement. Nutrient requirement for both crops vary.
