Answer:
C
Explanation:
The cell membrane is the layer surrounding the cell. This is like a barrier.
I know that you can think of some thing.
<span>Fossil evidence helped prove the theory of continental drift because similar fossils could be found on separate continents, in rocks of roughly the same age, surrounded by layers that matched each other, and in some cases, found nowhere else in the world.
Examples include Mesosaurus and Lystrosaurus. Both are reptiles found in places now separated by oceans. Neither could have swum such great lengths across salt water.
Another example includes the plant Glossopteris, a fernlike plant from about 250 million years ago. That plant has been found in small areas in Africa, South America, Australia, India, and Antarctica, all in small sections that lined up in Alfred Wegener's (the guy who developed the theory of continental drift) view of the supercontinent Pangaea. It should be note that those other fossils also lined up too. Glossopteris has a seedlike structure to it that was too large to be carried such great distances by wind and not strong enough (too fragile) to survive a trip by water. You ask what about birds? That's quite a distance for a bird to travel while carrying a large seed.
All of this together, along with evidence from landforms that matched up just like the fossils, and evidence from climate helped convince Wegener that continental drift had happened.

Explanation:
Vitamin C, ascorbic acid, is one of the most important vitamins found in citrus juices, including orange juice.<span> The temperature and storage time affects the percent of vitamin C content of orange fruits and orange juice. Different varieties of oranges also have different levels of vitamin C. The mid-season variety, Pineapple Orange had the highest levels, followed by the main early-season variety, Hamlin Orange. The late-season Valencia Orange had the lowest vitamin C content. Additionally, it was found that the longer the Valencia Orange fruit stayed on the tree, the lower the vitamin C level. </span>
Answer: circulatory system
Explanation:
Blood that return from the upper and lower parts of the body are deoxygenated hence they are transported to the heart for oxygenation. therefore blood enter the heart through vena cava ( the main vein) to the right auricles and it goes to the lower part of the heart which is the right ventricles which is more muscular. due to this blood is pumped from the right ventricles through pulmonary vein which pumps blood to the left ventricles through pulmonary artery and it is allowed to the left ventricles in the lower part of the heart and it pumped back in the body through the aorta( the main artery) .
