write an essay about importance of studying in environmental education?
Answer:
Environmental education increases public awareness and knowledge about environmental issues or problems. In doing so,individuals develop a deeper understanding of environmental issues and have the skills to make informed and responsible decisions.
Besides, it provides food, shelter, air, and fulfills all the human needs whether big or small. Moreover, the entire life support of humans depends wholly on the environmental factors. In addition, it also helps in maintaining various life cycles on earth.
In conclusion, environmental education has become a critical issue. In addition to individuals and governmental bodies, associations and learned societies have taken up the cause and published directories and handbooks about environmental education.

Risk of toxicity is higher with fat- vitamins. True or False
Answer:
True
Explanation:
The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity than water-soluble vitamins when consumed in excess. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals.
6. Why can't water be used to dissolve the
caffeine found in coffee and tea?
Alcohol is used to extract caffeine
Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.
What is solubility?The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.
Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.
It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.
Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.
Thus, water can not be used to dissolve the caffeine found in coffee and tea.

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea
Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)
Explanation:
Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.
What is the greenhouse effect?
Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.
More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.
A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.
Therefore the correct option is D.

Answer:
i think that the higher the body temperature the higher the cellular respiration
Explanation:
The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.
What is cellular respiration?In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.
In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.
After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.
Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

Which statements about wells are true? Check all that apply.
Wells bring groundwater from the unsaturated zone to the surface of the water.
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water from wells is generally not safe to drink.
Water gushes from artesian wells due to pressure.
Answer:
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water gushes from artesian wells due to pressure.
Explanation:
The statements that assert a true claim regarding the wells would be as follows:
b). Wells need to be drilled below the water table.
c). If water is pumped from a well too quickly, the well may run dry.
e). Water gushes from artesian wells due to pressure.
The above statements offer appropriate claims regarding the wells that they are required to be penetrated down the water table because it assists in striking the water from the lower levels as well. The next statement asserts that water must be transported from wells in a hurry because it can impact the yielding ability of the wells.The streaming of water from the artesian wells is primarily because of the pressure as it helps in the release of the water effectively.Thus, options b, c, and e are the correct answers.

Tell the story of the predator/prey loop.
If the owl population goes up, then ...
Answer:
Below : )
Explanation:
Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.
In this scenario, if the owl is the predator, as the population rises, its prey will decrease.
If the owl is the prey, the predators would most likely increase.
