Air pollution is one of the most serious threats facing national parks, harming visitors’ health, clouding scenic views and altering our climate.The air pollution affecting national parks — and the rest of the country — results from the burning of fossil fuels by power plants, oil and gas development, vehicles, agriculture, industrial emissions, and other sources. NPCA works to make sure our nation’s air laws are strong, to hold polluters and government accountable to those laws, and ultimately, to reduce the air pollution that harms our parks, climate and communities.
The Clean Air Act – which has helped improve air quality throughout the nation and the National Park System – is now under consistent threat as the Environmental Protection Agency works to roll back regulations, attack the use of science and offer polluters loopholes. NPCA advocates to defend and strengthen the clean air laws that protect park skies. We speak out for science and guard against policies driven only by politics and private industry.
Picture park skies free of pollution. While this sadly isn’t the case today, NPCA strives to make sure that parks are on the right track and that air pollution harming parks is reduced. We do this by helping to secure strong state plans to limit haze-causing and climate-altering pollution, and by defending existing plans – in court, if necessary.
Clean air laws are meaningless if polluters and the government don’t follow them. NPCA vigilantly monitors for sources that violate their permits or when officials aren’t following through on the safeguards in place to protect parks. We also look for opportunities to collaborate and work in state, local or regional processes to prevent threats of new pollution and help reduce harmful emissions.

B) False
2)The process of translation occurs at the ribosome
A)True
B) False
3)Transcription must occur before translation may occur
A) True
B) False
Answer:
1. False
2. True
3. True
Explanation:
hope this helps you :)
RNA contains ribose, not deoxyribose. Translation occurs at the ribosome. Transcription must occur before translation.
1) The sugar found in RNA is called deoxyribose
B) False
RNA contains the sugar ribose, not deoxyribose. Deoxyribose is the sugar found in DNA.
2) The process of translation occurs at the ribosome
A) True
Translation is the process of synthesizing proteins from mRNA at the ribosome.
3) Transcription must occur before translation may occur
A) True
Transcription is the process of synthesizing mRNA from a DNA template. It occurs before translation can begin.

glucose are bonded together differently. Because they have different
structures, they most likely - *
Starch
Cellulose
Glycogen
The complex carbohydrates pictured below are made by linking
molecules of glucose is Starch. Option A
Starch is formed through a process called photosynthesis in plants. Photosynthesis is the biochemical process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy stored in the form of glucose and other sugars. Starch serves as a primary storage form of this glucose in plants.
The linking together of the carbohydrates is what would lead to the starch formation.

Answer:
they perform different functions
Atmosphere
Biosphere
Geosphere
The correct answer is A. Asthenosphere.
Explanation
The earth is composed of three large layers: the nucleus, the mantle, and the crust. However, there are more layers within the main layers; in the case of the the asthenosphere, this is a layer of semi-molten materials that is located under the lithosphere (50 to 150km of depth) and has a thickness of around 650km. Additionally, this is located above the mesosphere, another layer of the crust that is part of the mantle, and extends to approximately 2700km deep. Additionally, this layer serves as a transition between the lithosphere and the mesosphere which are two major layers. So, the correct answer is A. Asthenosphere.
