Answer:
Sperm-egg interaction
Explanation:
The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.
Answer:
1. there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
2. Hurricanes are classified using the Saffir-Simpson Hurricane Wind Scale — a 1 to 5 rating that's based on maximum sustained wind speed, according to the National Hurricane Center.
3. When a hurricane strikes a coastal area, it brings a number of serious hazards. These hazards include heavy rains, high winds, a storm surge, and even tornadoes. Storm surge pushes seawater on shore during a hurricane, flooding towns near the coast. Heavy rains cause flooding in inland places as well.
