In many regions, wetlands have been filled in so as to be able to use the land for farming. Wetlands are vital for reducing the intensity of floods, as they tend to hold back some of the water. Without wetlands, flood will tend to wash increased sediment and pollutants into the ocean, which can have a detrimental effect on marine life. Coastal developments can also have a negative effect on marine life. The removal or moving of beach sand is in particular damaging to intertidal organisms that depend on specific coastal environments, and rocky shores can be smothered by sand, whereas sand environments can change into bare rocky environments. Impounding of rivers and reduced river flow can result in estuaries becoming closed. Many marine organisms, such as fish, depend on estuaries as nursery areas where they lay their eggs. Reduced opening of estuaries means that many fish species cannot reproduce. Built harbours result in changed currents and alteration of the sea floor, which also disrupts marine ecosystems.

Evidence of glacial action can be observed all over the park. Which of these are way
Maru [420]

Abrasion, plucking, deposition, and physical weathering are the glacial actions which can be observed all over the park.

Explanation:

When the huge ice masses slope down to fall over the land surface during a glacier, many glacial actions or processes take place which defines the landforms formed on the surface. These actions include abrasion, plucking, deposition, and physical weathering.  

Abrasion is an erosive process which scrapes the surface of ice rocks and other frozen rocky material beneath the ice and causes striations over the rocks.

Plucking also an erosive process plucks the frozen rocks beneath the ice surface.

Physical or freeze-thaw weathering causes water to enter the cracks in the rocks when the temperature increases. This water enters inside and freezes inside when the temperature goes down. This repeated melting and freezing of water destabilizes the rocks and will break the rocks.

These materials which are worn off are transported and deposition on the land surface when the glacier settle down.  

Longshore drifts occur along coastlines and brings materials along the coast when waves move at an angle with the coastline.

Explain why cells need to supercoil their dna molecules
Len [333]
DNA supercoiling means under or over winding of the DNA strand and basically is to become more condensed and more organized. Supercoiling is very important as it compacts the genetic code and as if that was not enough supercoiling also regulates and oversees the access the the genetic code.
