Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar moleculesfructose and glucose. Green plants use energy from sunlight to build sugarmolecules from carbon dioxide and
Answer:
The correct answers are "will not" and option B. "unit elastic".
Explanation:
The authors of an article in the New York Times about the New York Metropolitan Opera (the Met) suggest that the popularity of opera might be increased if the ticket prices for the opera are reduced, but in order to do so, the Met should receive a very generous economical gift. The authors of the article make this statement based on two assumptions: first, the Met will not increase its revenue as a result of the gift (therefore the money will be used to support a reduction in the ticket prices) ; and second, the demand for tickets to the Met is unit elastic (the demand would increase proportionally to the reduction in price, therefore the popularity of opera might be increased).
Answer:
2%
Explanation:
The scientist believe that around 2% of the species that existed on Earth have been preserved in the fossil records. It is still a hot debate about it though, as there are only around 250,000 species identified in the fossil records so far, which is less than a quarter from the species that live in the present.
The reason why scientists believe that the majority of the species have not been preserved are very logical though. One of the reasons is that lot of species existed very long time ago, so their remains just didn't lasted so long. Other reason is the movement of the plates, where we have situation where plates that existed in the past have been totally suducted and melted in the mantle, while others are at the verge of it, so every fossil with them is melted and destroyed too. Another reason is that lot of species do not have hard parts, solid bone structure, so their preservation has been pretty much impossible,
