Answer:
Then the scientists studied how this mineral behaved. For example, they looked into how dense bridgmanite becomes and how much it squashes. The team then compared these traits to what is known about the blobs themselves.
This research showed that in the lab, bridgmanite behaves much as does the mineral seen in the mantle’s blobs. The scientists also showed that bridgmanite isn’t rigid enough to hold together as an intact blob without help from something else. “This challenges the assumption that these piles are self-supporting,” Jackson says. “It’s evidence that there is something else propping them up.”
Lymph vessels send lymph fluid through nodes throughout the body. Lymph nodes are small structures that work as filters for foreign substances, such as cancer cells and infections. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid.
A dna double helix consists of a purine base, such as adenine and guanine, paired with its complementary pyrimadine base, such as thymine and cytosine.
Adenine pairs with thymine; A-T
Cytosine pairs with guanine; C-G
This happens through the food chain. Herbivores eat the plants and carnivores eat the herbivores. If plants did not use photosynthesis,they would die from lack of energy and the other organisms would suffer as well.
