Answer:

Water pollution; is when waste, chemicals, or other particles cause a body of water to become harmful to the fish and animals that need the water to survive. Water pollution can disrupt and negatively impact nature's water cycle as well.  A lot of water pollution comes from human activity. Some human causes include sewage, pesticides and fertilizers from farms, waste water and chemicals from factories, silt from construction sites, and trash from people littering.Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can actually suffocate. Sometimes pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Then bigger fishes eat the smaller fishes and get the pollutants too. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT. When birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished. Sewage can also cause major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up so much oxygen that there won't be enough left for the fish.Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.

How do scientists use fossils to study climate?<br> PLS HELP
faust18 [17]

Answer:

Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.

Landslides occur when earth materials that are no longer held by friction move down a slope with the help of gravity. I think th
xxTIMURxx [149]

Yes, the given statement is true.  

A landslide is illustrated as the movement of debris, the mass of rock, or earth down a slope. The landslides are a kind of mass wasting that signifies any down-slope movement of rock and soil under the direct effect of gravity.  

The slope movement takes place when the forces functioning on down-slope primarily because of gravity exceeds the strength of the Earth substances, which compose the slope. The causes comprise elements, which elevates the influences of down-slope forces and factors, which contribute to reduced or low strength.

The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.
