The noble gases are stable because they have how many electrons in their outer energy level?2
4
6
or 8

Answers

Answer 1
Answer: Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons. Noble gases are gaseous elements; Including , neon , argon, krypton xenon and radon. These gases belong to the group 0 (18) of the periodic table. I hope this helps

Answers

Ribosomes are organelles that create proteins. Cells use proteins to perform important functions such as repairing cellular damage and directing chemical processes. ... Without these ribosomes, cells would not be able to produce protein and would not be able to function properly.

How can photosynthesis be related to cellular respiration?

Answers

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Final answer:

Photosynthesis and cellular respiration are two interdependent processes. Photosynthesis uses carbon dioxide and water to produce carbohydrates and oxygen, while cellular respiration uses these carbohydrates to produce energy, carbon dioxide, and water. They form a cyclical biological harmony vital to life.

Explanation:

Photosynthesis and cellular respiration are two fundamental processes in the carbon cycle that share reciprocal reactants and products. In photosynthesis, plants absorb light energy to build carbohydrates in chloroplasts, using carbon dioxide and water. The resulting byproduct of this process is oxygen. On the other hand, cellular respiration occurs in the cytoplasm and mitochondria, where organisms metabolize these carbohydrates to produce energy, in the process releasing carbon dioxide and water. Both processes use electron transport chains to capture the energy necessary to drive other reactions.

Thus, photosynthesis and cellular respiration are linked in a cyclical biological harmony; they provide the life-sustaining energy that originates millions of miles away in the sun. Photosynthesis produces the carbohydrates needed for cellular respiration, and cellular respiration releases the carbon dioxide required for photosynthesis, creating an interdependent cycle vital to most forms of life on Earth.
