Answer:
According to the evidence, the Earth was formed about 4.6 billion years ago; Although there is no clear theory about how this happened, everything indicates that the Sun, Earth and other bodies in the Solar System were formed from the gravitational accumulation of a nebula. This was caused by the explosion of a nearby supernova, allowing the material to clump together.
Why was the Earth made up of layers?
There are two hypotheses in which the theory of accretion is based (Accretion: in astronomy it is the addition of matter to a body), and they indicate how the materials would have been grouped.
Even though the earth was created 6,000 to 10,000 years ago, this is according to research and scientists. :)
Waterborne pathogens can enter coastal waters via leaking sewer pipes and untreated wastewater.
Sewage and untreated wastewaters are filled with microbes some of which are capable of causing diseases to humans and livestock if given the opportunity. Hence, the seeping of these waters into coastal water is a risk to humans who might want to swim or make use of coastal waters.
Precipitation, changing of tides and the interactions of marine organisms and plants will ordinarily not form pathways through which pathogens can gain access to coastal waters.

Answer: True
Explanations:
Light diffraction is the bending of light around objects with very small openings whose sizes approach the wavelength of light.
Light scattering occurs in the transmission medium (such as air) due to density fluctuation, droplets, or particles in the transmission medium.
Phospholipids makes up majority of the cell membrane. Transmembrane proteins comes in second place.
