See the answer below
Explanation:
1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.
2. Cellular respiration can be aerobic or anaerobic.
Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.
Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.
3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.
During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:
During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:
D. Same energy level but different sublevel.
<h3>Explanation</h3>There are four quantum numbers [1]:
- <em>n</em><em>, </em>the principal quantum number,
- <em>l</em>, the orbital angular momentum quantum number,
- <em>
</em>, the magnetic quantum number, and
- <em>
</em>, the electron spin quantum number.
As their names might suggest:
- <em>n </em>determines the main energy level of an electron.
- <em>l</em> determines the type of sublevel of an electron.
- Each sublevel might contain more than one orbital. <em>
- Each orbital contains up to two electrons. <em>
The two electrons in question come from the same atom. The question suggests that they have the same <em>n</em>, <em></em>, and <em>
</em>. As a result, both electrons are in main energy level <em>n</em> = 3. They share the same spin.
However, the two electrons differ in their value of <em>l</em>.
- <em>l </em>= 2 for the first electron. It belongs to a <em>d</em> sublevel.
- <em>l </em>= 1 for the second electron. It belongs to a <em>p</em> sublevel.
