2) The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere.
3) It protect us from harmful UV rays and radiation and help to reduce temperature.
Answer:
1. What is ozone? Ozone is a gas that is made up of 3 atoms, and is extremely reactive.
2. Where is the ozone layer? The ozone layer is located in the stratosphere.
3. Why is the ozone layer important to us? The ozone layer is important to us because it protects the Earth from UVB that comes form the Sun.

What is the anammox reaction, and when does it occur in the nitrogen cycle?
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidises ammonium to di-nitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.
The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.
Thus, In order to avoid the buildup of too much nitrogen (such as nitrates and nitrites) in the environment, which can result in water pollution and other ecological issues, denitrification is an essential phase in the nitrogen cycle.
Low oxygen conditions, such as sediments in wetlands, wastewater treatment facilities, and oxygen-depleted regions of oceans, are where anammox bacteria carry out the anammox process.
In the end, this process aids in maintaining the balance of nitrogen in ecosystems and preventing nitrogen pollution by naturally removing excess nitrogen molecules from these habitats.
Thus, The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.

integrated pest management (ipm) is a pest control method founded on the principles of ecology. it involves using several control tactics based on a knowledge of the crop, pests and associated natural enemies. compared to traditional pesticide use on crops, how does a farmer implement ipm and what are the long-term goals?
The overall goal of IPM is to reduce the environmental and health risks of pesticides within social and economic constraints.
Fix: The scope of IPM implementation will continue to change greatly in the future. What began as limited approaches to promote integration of control methods for key pests and provide guidelines for decisions regarding pesticide applications is evolving to an ecologically-based systems approach.
why is Valparaiso Chile hotter than Sydney Australia if they are at the same latitude?
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. ...

Explanation:
An apparatus for measuring thermal conductivity employs an electrical heater sandwiched between two identical samples of diameter 25 mm and length 60 mm, which are pressed between plates maintained at a uniform temperature To = 77°C by a circulating fluid. A conducting grease is placed between all the surfaces to ensure good thermal contact. Differential thermocouples are imbedded in the samples with a spacing of 15 mm. The lateral sides of the samples are insulated to ensure one-dimensional heat transfer through the samples.
Required:
a. What is the thermal conductivity of the stainless steel sample material?
b. What is the average temperature of the samples?
The thermal conductivity of the stainless steel sample material is 30Q/ΔT.
Thermal conductivity
The thermal conductivity of the stainless steel sample material is calculated as follows;
[tex]k = \frac{Ql}{A\Delta T}[/tex]
where;
Q is quantity of heat transferred
l is the length of heat flow = 15 mm = 0.015 mA is the area ΔT is change in temperatureArea = πd²/4
Area = π(25 x 10⁻³)²/4
Area = 0.0005 m³
[tex]k = \frac{Q \times 0.015}{0.0005 \times \Delta T} \\\\k = 30\frac{Q}{\Delta T}[/tex]
Thus, the thermal conductivity of the stainless steel sample material is 30Q/ΔT.
More information is needed on the heat supplied to the samples and the final temperature.
