However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

D. Body systems are like individual parts of one big story.
Answers
Answer:
the answer would be b
Explanation:
the body sytsem needs to depend on eah other in order to work
Body systems are like runners in a marathon, who each run alone and don't need the other runners to finish the race, is not a good way to describe a body system, hence option B is correct.
How body systems work together?Your digestive tract takes nutrients and water from the food you eat in to your body. The body's cells receive oxygen, water, and nutrients through your circulatory system.
Your skin, excretory system, and respiratory system all function to remove wastes from your cells.
Your body's many systems depend on one another to function properly. While your heart's muscles require oxygen from your lungs to beat, your respiratory system depends on your circulatory system to distribute the oxygen it collects.
Therefore, option B is correct.

Corona
Explanation:
The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.
