Why is the environment more important than the economy?

Answers

We can’t live without an environment

But we can without an economy

The environment is more important than the economy because it provides us with clean air and water, healthy food, and preserved nature. These all components benefit human health and result in far more economic benefit than the economic cost.

What do you mean by Environment?

The environment may be characterized as the sum total of all sorts of living and non-living elements and their effects which consequently influence human life and other animals. There are basically two factors that contribute environment, i.e. biotic and abiotic factors.

The environment is more important than the economy because it delivers forests, rivers, oceans, and soils that provide us with the food we eat, the air we breathe, and the water we irrigate our crops with. We also rely on them for numerous other goods and services we depend on for our health, happiness, and prosperity.

What causes air to move towards the water from the land during the night?
Gravity moves the air towards the water because water is lower than the land.
The ground cools faster at night than the water which retains its heat warming the air above at.
The dry air over the land is heavier than the air over the water that contains more water vapor.
The ground retains the heat from the Sun longer than the water.

Answers

Answer:

C The ground cools faster at night than the water which retains its heat warming the air above at.

Explanation:

In simple words a land breeze is the flow of wind from the land towards the sea. During the night time, the land cools down quickly as compared to the day because there is no sun to heat surrounding air and the sea surface.

Explain why a food web is a better illustration of an ecosystem than a food chain

Answers

Answer:

In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

Explanation:

Food webs are more complex than food chains. Food webs show multiple organisms that predators eat while food chains don’t. If you need me to explain more I will! Hope I helped :)

Dew point is the temperature at which the rate of condensation equals the rate of evaporation.

True
False

Answers

Answer:

Called the dew point temperature, the point of saturation is where evaporation equals condensation. Therefore, a cloud results when a block of air (called a parcel) containing water vapor has cooled below the point of saturation. Air can reach the point of saturation in a number of ways.

Explanation:

The statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.

What is Evaporation?

Evaporation may be characterized as a type of chemical process through which an element or compound transforms from its liquid state to its gaseous state. This can certainly be achieved by consistently delivering energy to the compound.

Dew point temperature is the temperature at which air must be cooled in order to become saturated with water vapor. This water vapor is a form of a gaseous component that intermingles with the liquid components which are formed through the process of condensation. At this point, the rate of condensation equals the rate of evaporation.

Therefore, the statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.

Explanation:

Mitosis consists of specific phases that occur in a specific order. (PMAT!)

Prophase is the first phase of mitosis where chromosomes condense and become visible.  

Metaphase involves chromosomes moving to the center of the cell.  

Anaphase is where the chromosomes are equally pulled to either side of the cell.  

Telophase is where the chromosomes bunch up at either end of the cell and begin to unravel into their previous state.  

Cytokinesis then occurs where the whole cell divides between the newly forming nuclei.

What do you predict might happen if someone introduced a new species that could eat large amounts of algae at a rapid pace, outcompeting other species already present? Describe what you think might happen, making sure to specify how at least three of the organisms that might be affected and giving a detailed explanation for each organism. Make sure to include in your answer at least one organism that does not eat algae.

Answers

Answer:

Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!

describe how wind forms ocean waves in deep water and how these waves change as they develop in 6 sentences
PLEASE HELP

Answers

Wind-driven waves are created by friction between wind and surface water. When wind blows across the surface of an ocean the continual disturbance creates a wave crest. These waves can be created through local winds or distant winds. The waves can be affected by wind speed and wind duration. The faster the wind and the longer it blows, the bigger the waves. It also can depend on how far the wind blows uninterrupted.

I hope this helps :)
Wind forms ocean waves by creating friction between the wind and surface water. This creates a rising crest that forms into a wave. As the wind continues to blow, the waves also continue. Depending on the location, the waves change. For example, when deep water waves move to shallower waters, they change into breaking waves. As the wave travels into deeper waters, it slows down and the wavelength decreases.
