The Doppler Effect is evidence that the universe is expanding. When stars or galaxies are moving away from us, we see their color as red shifted. Because the distant galaxies are red shifted, this means that they are all receding with respect to Earth.

Here are the steps:
(1) Prophase
<span>(a) Early prophase when cells starts to break down some structures and build others up. It sets up the stage when the chromosome is dividing.</span><span>(b) Prometaphase, mitotic spindle begins to capture and organize the chromosomes.
</span>
(2) Metaphase
<span>The spindle has captured all the chromosomes. They lined them up at the middle of the cell making it ready for division.
</span>
(3) Anaphase
<span>The sister chromatids separate from each other and are pulled towards opposite ends of the cell.

Can someone write me an essay on the effects of pollution on the ocean? 500 words
Kryger [21]

Explanation:

Everything in this world we use comes from the ocean in some way. The air we breathe, the water we drink, even the products we use day to day, would not be possible without the ocean. That's why the issue of ocean pollution is so important and needs to be addressed as soon as possible. We depend on the ocean for so much in our life, without it we would surely become extinct. People seem to think that since the ocean is so large and vast, we can dump as much waste as we'd like into it and it will never have an effect on us. However, since we've been polluting the ocean as far back as Roman times, the evidence of ocean pollution becoming a major problem is all too clear. There are many different ways the ocean can become polluted.Fishnets improperly discarded into the ocean can also cause major issues, tangling into unsuspecting mammals and fish. According to the Marin Academy's Oceanography website, there are over 46,000 pieces of plastic floating in each square mile of ocean off the Northeast coast of the United States, which contributes to the death of 100,000 marine mammals and two millions sea birds yearly. A way you wouldn't expect pollution to be caused is by noise. The pressure from the sounds omitted by ships, sonar devices, oil rigs, and earthquakes can disrupt communication, hunting, migration, and reproduction patterns from many marine animals like whales and dolphins. This can throw the whole system off balance. Air pollution can also cause ocean pollution by being absorbed into the water and contaminating it, and vice versa. Ocean pollution can eventually cause air pollution. Dirt can also spill into waterways from top soil or silt from fields or construction sites, causing endangerment to fish and wildlife habitats. Out of all of these ways, oil spills can cause a noticeably excessive amount of damage to the ocean. Although only 12% of the oil entering the sea is caused by spills, they can deteriorate ocean life and environment more than any other pollution. One gallon of used oil spilled into the ocean, which contains toxic chemicals and heavy metals severely dangerous to the micro-organism at the base of the food chain, can cause an eight-acre layer

out at the beautiful ocean, the silky sand and gorgeous seashells lay underneath my feet. The blue waves crashing down onto the shore. The ocean is truly a beautiful sight to see. However, we are slowly ruining this beautiful thing because of the way we treat this planet, the ocean is extremely polluted and marine life is paying for it. A few of the ways mankind is damaging marine life is by heavy oil pollution, and exposing marine life to dangerous chemicals. One way our oceans are polluted is because.

Ocean Pollution Ocean pollution kills marine life everyday and damages the ocean in many ways that sometimes can't be fixed. The real question is where does it all go? Much of it ends up on our beaches washed in with the waves and tides, some sinks, some is eaten by marine animals mistaking it for food. The majority of pollutants going into the ocean come from activities on land. According to the United Nations Environment Programme (UNEP).

Ocean pollution is one of the most urgent issues in our world today. The ocean is crucial to our ecosystem and it is being severely damaged at an alarmingly increasing rate. In this paper I will educate about the role the ocean plays in our beautiful Earth, why it is being so widely ignored and dismissed, the causes of pollution, and its effects on animals and humans alike. Since the beginning of the human race, people have flocked to the ocean. The largest civilizations were built in fertile, coastal

The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans

I'm in the ocean every day, it’s my second home. Because of this, I am very sensitive to literary and other pollution that ends up in our oceans. I can't walk down the beach today without seeing a pile of trash. Because of this curiosity, I wanted to research what another type of litter fill our local ocean. Our ocean is filthy, Plastics and fibers make their way into the sea naturally every day. Apart from the rest of the trash, some of these plastics and fibers are microscopic, coining the terms.
