Answer:
A. Cellular Respiration.
Explanation:
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.

Imagine that the climate in your region became extremely arid, and freshwater became a scarce and precious resource. Wasteful uses of water, such as watering lawns and filling swimming pools, would be strictly outlawed, and water from the municipal water supply would cost 100 times what it does now. Discuss how you would adapt to that situation.

One way to adapt to this situation would be by reducing water use to strictly necessary activities and collecting water from alternative sources such as rain.
What would change in this situation?Due to scarcity, in this situation, people could not use water for recreation such as water in pools, and in general water usage is limited.
How to adapt to this situation?Possibilities are restricted in this situation since it is not a good idea to continue using water excessively. Instead, the best is to:

example of potential or kinetic energy?
Potential energy is the buildup of energy.
Example: When a bow is pulled back it creates a buildup of energy (potential energy) for the arrow to go forward.
Kinetic energy is the the energy of motion

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.

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.

in developed countries which of the following is a positive effect of agricultural changes in the past century?
A. Desertification
B. Clearing rainforests
C. Contamination due to run off
D. Amount of food produced has increased
E. Nutrient rich soil for farmland increasing
In developed countries , amount of food produced being increased is a positive effect of agricultural changes in the past century.
Agricultural changes in developed countries were set up such as application of fertilizers etc so as to achieve a maximum yield as the increasing population all over the world means increase in food production to cater for individuals and to prevent starvation and death.
Agricultural changes were also done to ensure goods produced have a very high quality.
The remaining options such as Desertification, Clearing of rainforests and contamination can be referred to as part of the negative effect of agricultural changes in the past century.

It is very difficult to add or remove electrons from an atom that has eight electrons in its outer shell.
True
False
Explanation:
Electrons are typically removed from the valence shells, which are the highest s and p orbitals. Also, Hund's rule still applies here, but backwards. Electrons will be removed from their orbitals until all of them are unpaired, and then the unpaired ones will be removed.
May be true because velence shell is the outermost shell which can be removed.
