Type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
The answer is 12.5%.
Each gram of protein has four calories. Therefore, 50 grams of protein contain 200 calories. In order to find the percentage of total energy intake that comes from protein, we need to do the division: 200/1600 * 100 = 12.5. Protein is needed for body growth and maintenance and energy.
The correct answer is - That some force lifted the rocks from the water.
The fact that there's sedimentary rocks on the tops of the mountains is an evidence that there has been some force that managed to lift upwards parts of the seafloor. Taking into consideration how slowly this force manages to lift up parts of the Earth, we can easily assume that the Earth is very old. The amount of time that is needed for a part of the seafloor to be lifted few thousand meters upwards is counted in tens of millions of years, thus giving us evidence that the Earth has been around for a very long time.
Answer:
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
