Answer:
Go through your kitchen waste. Vegetables and fruit peelings are the number one food remnants you should keep aside. ...
Add other organic materials to the compost. ...
Collect some garden waste. ...
Create the compost. ...
Apply the fertilizer.
Answer:
AbstractOrganic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance. WHO guidelines for the reuse of excreta and other organic matters identify the risk for the exposed groups to the reuse of the

How did the industrial revolution contribute to global climate change
Answer:humans have put ridiculous amounts of carbon dioxide into the atmosphereThese events are linked to the mass burning of fossil fuels to meet an increase in human demand
So the answer is True
Explanation:
Burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of Earth includes five primary layers and a number of minor ones.
Industrial revolution is defined as the transition of an economy based on agriculture and handicrafts to one driven by industry and machine production. The causes of industrial revolution are the advent of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution are some of the factors that historians have recognized as contributing to the Industrial Revolution.
Thus, burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

Explanation:
Chlorine and oxygen form many different compounds, including CIO, and Cl2O3. How do the names of these compounds differentiate one chlorine oxide from another?
Answer:
We can mix two compounds and create a third that bears little resemblance to its parents. For instance, by mixing two parts of hydrogen gas with one of oxygen - liquid water is formed. We should not be misled by the fact that chlorine and chlorine dioxide share a word in common. The chemistries of the two compounds are completely different.
Chlorine and chlorine dioxide are both oxidizing agents (electron receivers). However, chlorine has the capacity to take in two electrons, whereas chlorine dioxide can absorb five. This means that mole for mole, ClO2 is 2.6 times more effective than chlorine.
If equal, if not greater importance is the fact that chlorine dioxide will not react with many organic compounds, and as a result, ClO2 does not produce environmentally dangerous chlorinated organics. For example; aromatic compounds have carbon atoms arranged in rings and they may have other atoms, such as chlorine, attached to these rings, to form a chlorinated aromatic - a highly toxic compound that persists in the environment long after it is produced.
Chlorine dioxide's behaviour as an oxidizing agent is quite dissimilar. Like ozone, the predominant oxidation reaction mechanism for chlorine dioxide proceeds through a process known as free radical electrophilic (i.e. electron-attracting) abstraction rather than by oxidative substitution or addition (as in chlorinating agents such as chlorine or hypochlorite). This means that chlorinated organic compounds such as THMs and HAAs are not produced as a result of disinfection using chlorine dioxide
Hope this helps, have a nice day! :D
The way that the names of these compounds show that the Chlorine oxides are different is by making reference to the number of individual molecules in the compound.
How are the chlorine oxides differentiated?The number of chlorine and oxygen molecules in each compound are used to name the compounds which ensures that they are differentiated.
ClO₂ is called "Chlorine Dioxide" which shows that there are two Oxygen atoms.
Cl₂O₃ is called "Dichlorine Trioxide" which shows that there are two Chlorine molecules and 3 Oxygen molecules.

Look at the three kinds of houses shown in the simulation. Which house do you think will best resist damage from a tsunami? Which house will suffer the most damage from a tsunami? Do you think any of the houses will survive a large tsunami? Write down your predictions.
Answer:
The brick house will best resist damage from a tsunami, and the straw house will suffer the most damage from a tsunami. I predict these reasons because brick has a stronger material than the rest of the houses, while the straw house has the weakest material than the rest of the houses. No, I do not think any of the houses can survive a massive tsunami because if the tsunami was 22 feet tall, the brick house would become damaged due to the lack of support. And, the other houses can't take a tsunami higher than 10 feet. The brick house can only take tsunamis less than 20 feet.

9*24 = 216 seconds = 3.6 minutes
Explanation:
Answer:
216 Seconds

The first stage of the experiment is focusing only on the physical properties of acidic property.
What is physical property?A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.
Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.
