I can't see an options so it's complicated to answer this question. But I think I've forund what you mean via Internet. So in my opinion the right one is <span> "Get into a bikini by this summer with our muscle toner machine." </span>
Food is squirted from the stomach into the small intestine. Here it mixes with digestive juices from the liver and pancreas. Bile from the liver breaks up fat. Pancreatic juice neutralizes stomach acid and contains enzymes that digest carbohydrates, proteins, and fats.
C. The uneven heated of Earth's different surfaces. For e.g., land changes temperatures quicker as compared to the sea.
When the sun comes up, the land heats up quicker than the sea. As a result, air above the land will also heat up more than air above the sea. As hotter air rises from the land, the cooler air travels to the space which the hotter air rose from. This creates wind, or a cycle of air currents.
Hope this helps! :)
P.S. By the way, this seems to be more so of Geography as compared to Biology. :) No worries though!
The answer is C. decreases.
C-14 and C-12 are carbon isotopes used to measure the approximate age of organic remains. C-12 is stable, and it does not break down into other elements over time. C-14 is not stable. It breaks down into N-14.
Organisms can incorporate C-14 into their bodies during the life. But when the die, C-14 is not incorporated anymore. After organisms' death, C-12 will remain stable, but C-14 will start to breaks down into N-14. So, it will be less C-14 and C-12 will remain the same. The ratio of C-14 to C-12 must decrease over time.
