The scale let's us know how far apart certain places are on a map. It can also tell us how high something is, for example, a mountain, which is represented by contour lines on a map. Hope this helps!
They fire a harpoon-like filament called a nematocyst into their prey. Once injected with the paralyzing neurotoxin, the prey is guided into the mouth by the tentacles.

Answer:
requirement for the intensification of tropical cyclones is that there must be little change in the wind speed with height above the surface. If the winds increase too much with altitude, the core of the system will no longer be vertically aligned over the warm surface that provides its energy.
The NIST-F1 Cesium fountain clock is in Colorado. It is the standard for primary time and frequency in measuring time.
The NIST laboratories in Boulder, Colorado, developed the cesium fountain atomic clock NIST-F1, which serves as the country's primary time and frequency standard. NIST-F1 is a member of the global network of atomic clocks that establishes Coordinated Universal Time (UTC), the recognized global time.
The NIST-F1 is known as a fountain clock because it measures frequency and time intervals by using the atoms' fountain-like movement. Atomic clocks are the most precise means of measuring time intervals, or the amount of time that separates two events.
Atoms in the clocks leap from one energy level to another due to the precise frequency at which these clocks emit electromagnetic radiation, such as microwaves.
