Answer:

They all start out as a single cell and develop the same pattern of structures such as tails and pharyngeal slits. Some of those structures remain as the embryo gets older, but others go away.

Do cnidarians have an endoskeleton, exoskeleton, or no skeleton?
Sav [38]
In medusae, mesoglea comprises the bulk of the animal and forms a resilient skeleton. In polyps, the water-filled coelenteron acts as a hydrostatic skeleton, which, in concert with the mesoglea, maintains the form of these animals. Muscles in cnidarians are extensions of the bases of ectodermal and endodermal cells.

What is a geostrophic wind? Why would you not expect to observe a geostrophic wind at the equator?
elena-14-01-66 [18.8K]

A theoretical wind known as the geostrophic wind is produced when the Coriolis effect, as well as the pressure difference forces, are balanced (PGF). It is a decent estimate for the wind reported at middle latitudes at an altitude of greater than 1 km. Given that there is no Coriolis effect near the equator, there can be no geostrophic wind.

What does "geostrophic wind" mean?

Geostrophic flow, as used in atmospheric research, is the fictitious wind that would emerge from a precise balancing act between the Coriolis effect and the pressure difference forces. The term "geostrophic equilibrium" or "geostrophic balance" refers to this situation (also known as geostrophy). Parallel to the isobars is where the geostrophic wind is pointed. In nature, this equilibrium seldom occurs perfectly. Because of these factors, the genuine wind and geostrophic wind nearly never match up.

The location of geostrophic winds:

At elevations exceeding 1000 meters (3300 feet), geostrophic wind can be found. With the use of weather balloons, the geostrophic wind velocity may be calculated. At heights up to 100 meters, the ground surface has a significant impact on winds.
