<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
Answer:
muscle cells in the legs of a marathon runner
Explanation:
Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.
Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.
The answer is e. global wind patterns
Answer: There is a lot
Explanation:
You're made partly of carbon, so is clothing, furniture, plastics and your household machines. There is carbon in the air we breathe. Diamonds and graphite are also made of carbon.
<span>In this case, all these statements are true. Salinity is the salt in the water. Jacques Piccard and Lt. on Walsh were the first people to explore the deepest part of the worlds ocean known as the Mariana Trench in The Challenger Deep, and Jason 1 is a satellite released by NASA to monitor world ocean circulation and study the way the atmosphere and ocean interact with each other to improve the predictions for the climate when it comes to major weather events like El Nino.</span>
