Mitosis and meiosis are similar processes, but they have some very important differences. Explain how mitosis and meiosis are al
solmaris [256]
Similarities: Mitosis and meiosis both involve cell replication. They both involve prophase, metaphase, anaphase, and telophase.
Differences: Meiosis creates gametes while mitosis creates somatic cells. Mitosis creates two daughter cells, while meiosis creates four sperm cells in men and one egg cell and three polar bodies in women. Mitosis involves one round of cell division, while meiosis involves two. Mitosis creates cells that have the same number of chromosomes as the original cell, while meiosis creates cells that have half the number of chromosomes as the original cell.
Hope that helped you. 
P.S. There are more similarities and differences, challenge yourself and see if you can find them! Good luck.

What landform develops on coral reefs as a result of wave action
Talja [164]
A reef is a ridge of a rock of any type of land that extends some distance just under the surface of the water. A coral reef is a lot of calcium carbonate that is also made up of living creatures. A coral reef is created when a small amount of dead coral turns into calcium carbonate. This process is very slow. The famous reefs are the Great barrier Reef of Austria and Belize and Cayman Islands.
Wave actions are usually not a problem due to hard coral reefs. The reef reduces a wave energy. But sometimes waves can break off or flatten large portions of coral reefs, forming grooves in once circular reef. The higher areas between the grooves are known as buttresses and may grow together at the top producing arches. 
Answer:  Landform that develops on coral reefs as a result of wave action are Arches.
