What is the immovable object in a supernova explosion? choose one: a. the outermost layers of the star b. the intermediate layer
balandron [24]

The <u>innermost core</u> is the immovable object in a supernova explosion.

<h3>What is Supernova?</h3>
  • The enormous and dazzling explosion of a star is known as a supernova.
  • This sporadic astronomical event occurs either when a white dwarf is sent off into uncontrollable nuclear fusion or in the latter stages of the formation of a massive star.
  • The initial object referred to as the progenitor either entirely vaporizes or falls into a neutron star or black hole.
  • A supernova's peak optical luminosity can be comparable to that of an entire galaxy before diminishing over the course of a few weeks or months.
  • The most recent supernova remains have been found, although Kepler's Supernova, which happened in 1604, was the last one in the Milky Way that could be directly observed.

What are the consequences of increased nitrogen and phosphorus into water systems?
larisa86 [58]

Nutrient pollution has impacted many streams, rivers, lakes, bays and coastal waters for the past several decades, resulting in serious environmental and human health issues, and impacting the economy. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.

<u>What are two sources of increased nitrogen and phosphorus in a river that result from human activity?</u>

Phosphorus (P) and nitrogen (N) are the primary nutrients that in excessive amounts pollute our lakes, streams, and wetlands. Nitrogen is essential to the production of plant and animal tissue. It is used primarily by plants and animals to synthesize protein.

<u>What happens if there is too much nitrogen in an aquatic ecosystem?</u>

Excess nitrogen can harm water bodies. Excess nitrogen can cause overstimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters.

<u>How does phosphorus affect algae growth?</u>

Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.

<u>What are the effects of nitrates and phosphates in aquatic ecosystems?</u>

However, at night, dissolved oxygen may decrease to very low levels as a result of large numbers of oxygen consuming bacteria feeding on dead or decaying algae and other plants. Eutrophication – “The process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates.

<u>Why do nitrogen and phosphorus promote algae growth?</u>

Nutrients promote and support the growth of algae and Cyanobacteria. The eutrophication (nutrient enrichment) of waterways is considered as a major factor. The main nutrients contributing to eutrophication are phosphorus and nitrogen. ... This phenomenon encourages the growth of algae.

<u>Why is too much nitrogen and phosphorus bad for the environment?</u>

Nutrient pollution is one of America's most widespread, costly and challenging environmental problems, and is caused by excess nitrogen and phosphorus in the air and water. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.

Hope this helps :)
