List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
Answers
Liquid water at 25 deg is so rapidly breaking bonds between H2O units and reforming them that extra water molecules get trapped inside the water lattice. This is the reason why liquid water is more dense than solid water.
The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules. At low temperature, more of the water has the same lattice as ice.
Wikipedia, Water Density
It is possible to have liquid water at temperatures well below 0 deg C. Molecules in this supercooled water are free to move. Bonds are made and broken. The long range structure is not perfect but the short range structure of supercooled water is very much like ice. Adding a crystal to supercooled water causes instantaneous ice formation.

The poles are opposite, so opposite closer together and the distance is closer together, so there is stronger magnetic field
The pair of magnet that have the greatest magnitude would be Pair 1.
Why do they have the greatest magnitude ?Magnets will only attract each other and therefore have a great magnitude if they are facing opposite poles. Pair 3 are therefore out because it has the same pole facing the other.
Magnitude of magnetic force will increase the closer the magnets are to each other. Seeing as Pair 1 has the lowest distance of 0. 3 cm, it means that Pair 1 would have the greatest magnitude.

Water, carbon and nitrogen cycles are biogeochemical cycles that exist in the biosphere to maintain a balance in the flow of energy and matter.
What patterns are observed in the cycles?There are three major biogeochemical cycles - water, nitrogen and carbon - that exist in nature which allow the transfer of matter and energy between the living and non-living things of the biosphere.
All the three cycles involve the exchange of gases from the plants to atmosphere to the animals or microbiota, which is again released back into the atmosphere.
Plants absorb the nitrogen, carbon and water in different forms from the environment which is then passed on.
Another similar pattern seen amongst the three is that humans release carbon, nitrogen and oxygen in various forms.

How do fossil fuels play a role in the carbon cycle?(1 point) Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere. Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Answers
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
The amount of carbon in the form of carbon dioxide in the atmosphere is about 0.03% by volume. This value is kept fairly constant by a natural process known as the CARBON CYCLE. This involves carbon dioxide being continually removed from the atmosphere by plants in photosynthesis, rain water as weak acids while in order to maintain this balance, carbon dioxide is at the same time returned to the atmosphere by:
→ burning of carbon containing substances (fossil fuel)
→ respiration of plants and animals and
→Decomposition of organic substances.
Hence, Fossil fuels which are rich in carbon content releases carbon into the atmosphere when burnt.
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.
Does the pattern in a food chain support the conclusion that climate change is caused by human activity and deforestion? Why or Why not?
Answers
Answer: No, it does not directly.
Explanation:
The pattern in a food chain cannot directly support the conclusion that climate change is caused by human activity and deforestation, as food chains only describe the transfer of energy and nutrients between different organisms in an ecosystem. However, the impacts of climate change and deforestation can disrupt food chains and have cascading effects on ecosystems, which can ultimately lead to the extinction of certain species and the loss of biodiversity.
Human activities, such as burning fossil fuels, deforestation, and agricultural practices, contribute to the emission of greenhouse gases, which trap heat in the atmosphere and cause global temperatures to rise. This increase in temperature can have a range of effects, including changes in precipitation patterns, rising sea levels, and more frequent and intense extreme weather events.
These changes can disrupt the habitats and food sources of many species, causing declines in their populations and even extinction in some cases. For example, deforestation can lead to the loss of habitat for many species, including those that are important components of food chains. Additionally, changes in precipitation patterns can affect the growth of plants and the availability of food for herbivores, which can then impact the populations of predators that depend on these herbivores for food.
In summary, while the pattern in a food chain itself does not provide direct evidence for the causes of climate change, the disruption of food chains and ecosystems due to human activities and deforestation can contribute to climate change and its impacts.
No, a food chain's pattern does not conclusively prove that human activity and deforestation are to blame for climate change.
The pattern in a food chain does not necessarily prove that human activity and deforestation are to blame for climate change. Natural processes, greenhouse gas emissions, changes in land use, and other factors are only a few of the many influences on the complex phenomenon known as climate change. While human actions like burning fossil fuels can raise greenhouse gas concentrations and deforestation can lessen carbon sinks and release stored carbon into the atmosphere, these factors cannot simply be attributed to the pattern in a food chain.
A thorough examination of the diverse scientific facts and evidence from numerous disciplines, such as atmospheric sciences, climatology, and earth sciences, is necessary to comprehend and handle climate change.
