a hurricane occures
Yes, it is true!

Sperm travels with the help of their tails. They are implanted into the cervix. From there, the sperm will travel up through the canal to reach the embryo to fertilize.
The flagella are located on the collar cells inside the sponge. When the sponge takes in water, the flagella reach out and grab the food that is found inside the water.
When you inhale in the lungs the air goes into little sacks called alveoli. In the alveoli gaseous exchange occurs this is when the carbon dioxide from the capillaries is exchanged for the oxygen you inhaled. When in the capillaries the red blood cells absorbs the oxygen and transports it around the body until all the oxygen is absorbed by the body it is then brought backed to the lungs where gaseous exchange occurs again.
Could be bad, but not if you get it removed as soon as possible, preferably within 12 hours at very most. If you can't reach it yourself, see a doctor. Leaving it and doing nothing is NOT an option.
Molecules move from an area from where there is a high concentration to an area where there is a low concentration. This occurs until equilibrium is reach. After equilibrium is reached, diffusion still occurs. (but in "equal trade") Diffusion is caused by the random movements of molecules.
A hurricane or typhoon depending on where it occurs.
When maximum sustained winds reach 39 mph.
When the sustained winds of a tropical cyclone reach 74 mph it is considered a hurricane.
A tropical depression is a tropical cyclone with winds under 39 mph. When winds reach or exceed that limit it is called a tropical storm and is given a name. Tropical depression 9 denotes the 9th tropical cyclone of that year in a particular ocean basin.
A tropical cyclone officially becomes a hurricane when sustained winds reach 74 mph (119 km/h)
They are both intensity levels of tropical cyclone. A tropical depressions forms when a tropical disturbance gains a defined center of circulation, but has sustained wind under 39 mph. If it continues to strenthen, it will become a tropical storm when winds reach 39 mph and a hurricane when winds reach 74 mph. Most hurricanes start development as tropical depressions.
A hurricane is a tropical cyclone with sustained winds of at least 74 mph. A tropical depression is a tropical cyclone with winds less than 39 mph. Above that limit it is considered a tropical storm. A tropical depression is of much lower intensity and is generally not as well organized as a hurricane.
A tropical depression is a weak tropical cyclone wind sustained winds of less than 39 miles per hour. As the depression is fueled by moisture from warm ocean water it gains strength and becomes more organized. When wind speeds reach 39 mph it becomes a tropical storm. When they reach 74 mph it becomes a hurricane.
A hurricane cannot be a tropical storm as by definition a tropical storm is weaker than a hurricane. A tropical storm is a tropical cyclone with winds of 39-73 mph. Only when winds reach 74 mph or greater is the storm considered a hurricane. A hurricane can weaken into a tropical storm and from there into a tropical depression (winds under 39 mph). A tropical storm or depression may also degenerate into a remnant low, which is too disorganized to be considered a tropical cyclone. A tropical cyclone (hurricane, tropical storm, or tropical depression) may also become an extratropical cyclone after moving over land or cold water. Around the world hurricanes have different names. In the northwest Pacific ocean they are called typhoons, In the Indian ocean they are called intense tropical cyclones, and in the south Pacific they are simply called cyclones. However, these are just different names for essentially the same kind of storm.
Tropical disturbance -> tropical depression -> tropical storm -> tropical cyclone (hurricane). *Hurricane is a local name, for tropical cyclones (official name) that appear in the Atlantic.
To qualify as a hurricane a tropical cyclone must have sustained winds of at least 74 mph. In rare cases, however, hurricane winds can reach nearly 200 mph.
No, it is not. Cyclone Tracy was the smallest storm to reach hurricane intensity, bu was strong enough to be considered a major hurricane. Hurricane Andrew, a category 5 hurricane, was also relatively small. By contrast Typhoon Tip was the largest tropical cyclone on record and also one of the strongest.
