Answer:

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.

Paraphrase this quote, “Sometimes you have to go up really high to understand how small you really are.”
Helga [31]

Answer:

Sometimes you just have to get yourself hard to understand what you are really going through and how much you have done and how hard you are.

Explanation:

Tbh not all quotes are easy to express but this one sounds really interesting.

But in my opinion this is the best I could describe

Hope you agree. Let me know :)

describe how these nutrients and elements such as carbon, oxygen, and nitrogen are cycled through ecosystems.
Diano4ka-milaya [45]

Answer:

Carbon Cycle

Steps of the Carbon Cycle

  • CO2 is removed from the atmosphere by photosynthetic organisms (plants, cyanobacteria, etc.) and used to generate organic molecules and build biological mass.
  • Animals consume the photosynthetic organisms and acquire the carbon stored within the producers.
  • CO2 is returned to the atmosphere via respiration in all living organisms.
  • Decomposers break down dead and decaying organic matter and release CO2.
  • Some CO2 is returned to the atmosphere via the burning of organic matter (forest fires).
  • CO2 trapped in rock or fossil fuels can be returned to the atmosphere via erosion, volcanic eruptions, or fossil fuel combustion.

Nitrogen Cycle

Steps of the Nitrogen Cycle

  • Atmospheric nitrogen (N2) is converted to ammonia (NH3) by nitrogen-fixing bacteria in aquatic and soil environments. These organisms use nitrogen to synthesize the biological molecules they need to survive.
  • NH3 is subsequently converted to nitrite and nitrate by bacteria known as nitrifying bacteria.
  • Plants obtain nitrogen from the soil by absorbing ammonium (NH4-) and nitrate through their roots. Nitrate and ammonium are used to produce organic compounds.
  • Nitrogen in its organic form is obtained by animals when they consume plants or animals.
  • Decomposers return NH3 to the soil by decomposing solid waste and dead or decaying matter.
  • Nitrifying bacteria convert NH3 to nitrite and nitrate.
  • Denitrifying bacteria convert nitrite and nitrate to N2, releasing N2 back into the atmosphere.

Oxygen Cycle

Oxygen is an element that is essential to biological organisms. The vast majority of atmospheric oxygen (O2) is derived from photosynthesis. Plants and other photosynthetic organisms use CO2, water, and light energy to produce glucose and O2. Glucose is used to synthesize organic molecules, while O2 is released into the atmosphere. Oxygen is removed from the atmosphere through decomposition processes and respiration in living organisms.

Which of the following statements is false?

Answer:

a is write

Explanation:

Why are all ionic compounds crystalline in structure?

Ionic compounds are generally hard, but brittle. ... The repulsive forces between like-charged ions cause the crystal to shatter. When an ionic crystal breaks, it tends to do so along smooth planes because of the regular arrangement of the ions.
