Explanation;
-About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa.
-The movement of Earth's tectonic plates formed Pangaea and ultimately broke it apart. Pangaea existed during the Permian and Triassic geological time periods, which were times of great change.
The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.

One of my passions is keeping up with creationist (and I include Intelligent Design here) attempts to change what science is. They wish to supplant the reason and evidence that is the basis for good science with faith instead – specifically their faith.
Sometimes, actually often, it can become discouraging looking at how many battles must be fought to ensure our schools continue to teach good science; listening to all the politicians expressing their ignorance of science by expressing doubts about evolution; and seeing all the letters and forum responses from those who let their religion totally blind their ability to reason and fairly judge evidence.
For example, consider these quotes from various prominent politicians:
“There are clear indications from our people who have amazing intellectual capability that this didn’t happen by accident and a creator put this in place,”
“Now, what was his time frame and how did he create the earth that we know? I’m not going to tell you that I’ve got the answers to that,” Perry said. “I believe that we were created by this all-powerful supreme being and how we got to today versus what we look like thousands of years ago, I think there’s enough holes in the theory of evolution to, you know, say there are some holes in that theory.” Governor and Presidential candidate Rick Perry
Answer: Cell membrane is layer which is present in all living cells. It is present under the cell wall but in some cases such as plant cells.
Explanation: It is composed of lipid bilayer and proteins embedded in it. Phospholipids, glycolipids and sterols is the composition. Its function is to protect the cell from extracellular environment. It is semipermeable membrane that js allow only selected molecules to pass.
