Natural gas burns
cleaner than coal, yet it is considered a pollutant. Why?
Answer:
Cleaner burning than other fossil fuels, the combustion of natural gas produces negligible amounts of sulfur, mercury, and particulates. Burning natural gas does produce nitrogen oxides (NOx), which are precursors to smog, but at lower levels than gasoline and diesel used for motor vehicles.

What are three ways radioactive dating is or was used in the real world?
Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating.
Answer:
Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past

Which of the following is not a contributing factor to ecosystem stability species, genetic,ecosystem, or abiotic diversity.
Answer:
Ecosystem.
Explanation:
Ecosystem is not a contributing factor to ecosystem stability whereas, species, genetic, and abiotic diversity are the factors that contributes in the stability of an ecosystem. The diversity of species greatly affected the ecosystem stability if more species are present in he ecosystem. The abiotic factors also plays an important role in the stability of an ecosystem because these abiotic factors causes changes in the ecosystem environmental conditions.
water in plants can be lost through what
Answer:
transpirationExplanation:
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
I hope my answer will help you keep safeFor a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration gradients such that a signal can be propagated down the axon of a neuron without the necessity of ATP. The system could have worked the opposite way. The neuron could have used ATP to move ions across when a signal was being propagated and then allow natural diffusion to return the ions to their respective sides of the membrane. What advantage does the organism have using ATP up front
Answer:
The lack of ATP would slow nerve responses to generate an action potential
Explanation:
Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

Explanation:
Explain why there must be at least one barrier to reproduction in order for speciation to occur
Answer:
Speciation occurs when a single species becomes two or more separate species, which can no longer interbreed with one another. Reproductive isolation is required for speciation. Reproductive isolation means the groups in question cannot mate with one another, often because of physical barriers.

Choose ALL that apply. A) Top level predators may leave the area in search of food. B) Overall, there will be a reduction in biodiversity in the area. C) Once prey species are caught, the food web in the area will be disrupted. D) Predators from other regions will move in to replace absent polar bears and seals. E) The trawl net will scoop up everything in its path, including marine life and seafloor structure.
Answer: A, B, C, E
Explanation: USA test prep
The Arctic marine habitat comprises diverse ecosystems such as special ice berms, long year sea ice, etc. Therefore applicable statements are A, B, C and E.
Why is the Arctic habitat important?The Arctic is a special ecosystem with a complex food web made up of organisms acclimated to its harsh conditions.
It supports multiple large fisheries and massive populations of roaming birds that come to the Arctic in the summer to mate.

Which level has the most number of organisms but the least specific characteristics?
Answer:
Kingdom
Explanation:
Out of all the taxonomic categories, the Kingdom is the least specific, which means it has the least filters.
I like to think of taxonomic categories as filters/sieves. If you put your animals through the Kingdom filter, then all the animals are in that category. if you have a finer sieve, then less animals get through, this goes down all the way to the most specific which is Species.

Write an argument for or against the idea of using controlled fires to protect wild areas.
Answer:
Wild forest fires cause extensive damage to flora and fauna and result in the destruction of man-made property in and around the area of the fire. To maintain the health of the forest and prevent the large wild forest people or man]nagers use prescribe fire or controlled fired when there is no risk of loss of life and resources.
These controlled fires are used by forest officials and fire managers to prevent or keep wildfires at bay. It helps in cleared-off areas by playing the role of a barrier for fire from spreading further.
There is always the risk of flora fauna and the life of wild animals. They can get killed and lose their habitat and the smoke rose from this fire causes for environmental concern too.

What are the types of vascular plants? How do they reproduce?
crytogams - this type of vascular plant reproduces by spore.
phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.
Angiosperms - this type of vascular plant reproduces flowers and fruits
Gymnosperms - this type of vascular plant reproduces cones and seeds only.
Answer:
Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).
Explanation:
Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.

There is something new! There is now 5 seasons instead of 4. Everyone is really happy. It is called the second summer. This is pretty cool because summer does not last very long, and with a second summer it could last longer.
Some people might not enjoy having a longer summer though. It is a big change for everyone. Me and my friends like summer because there is more time for us to do things together, and spend more time together. Summer is fun for a lot of people for example, there is no school. When you dont have school it makes more time for people to spend with family and friends.
If there is a second summer there is more time to spend outside, with friends, going on trips with family, and lots of other things. This is because there would be more time off school. If there was more time off school then there is more free time to do what ever you want. But.... some people do not like summer as much as others. The people that dont really like summer would just have to get used to it. There is nothing you can do that is part of earths rotation.
So if there is 5 seasons now, no one can change it. They can not change it because no one can rotate or tilt the earth. The earth tilts when it is changing seasons. No one can just go up and tilt the earth so they could have the season they want. But that is what i think would be cool if there were 2 summers. Also during summer is when family, and Friends can plan vacations. So people could go on vacation more to!
