The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs.

Unlike coelomates (eucoelomates), animals with a true body cavity, acoelomates lack a fluid-filled cavity between the body wall and digestive tract. Acoelomates have a triploblastic body plan, meaning that their tissues and organs develop from three primary embryonic cell (germ cell) layers.

Pseudocoelomate animals have a pseudocoelom (literally "false cavity"), which is a fluid filled body cavity. Tissue derived from mesoderm partly lines the fluid filled body cavity of these animals. Thus, although organs are held in place loosely, they are not as well organized as in a coelomate.

Answer:

The main difference between acoelomate and coelomate is that acoelomate is an invertebrate that doesn't have a coelom whereas coelomate is an invertebrate that has a true coelom.

A coelom is a fluid-filled body cavity, which is completely lined by the tissues derived from the mesoderm.

What is the difference between good ‘seeing’ and good ‘transparency’? Give one condition for each.
iren [92.7K]

Answer:

Transparency is the <u><em>opacity of the atmosphere</em></u>, or how clear it is. Moisture and humidity lower the transparency, as does smoke or other kinds of pollution. It’s not entirely unlike light pollution in that it washes out the fainter details of astronomical targets. In fact, poor transparency typically makes light pollution worse because it scatters the light around instead of letting it escape into space away from your cameras and optics.

Transparency usually gets better with altitude, because you're looking through less air. That's why high altitudes are prized for observatories and star parties.

Transparency is also usually very good after a rainstorm has come through to clear all of the particulates out of the air. This is reason number one I figured my second friend had it right at the star party.

Seeing, on the other hand, is a measure of <u><em>atmospheric turbulence</em></u>. We know that if we take a photo of a fast-moving subject, such as at a sporting event, with a low shutter speed, we'll get a blurry image. So what happens when you have to take a very long dark-sky photo and the stars are jumping all about due to atmospheric turbulence? That’s right, blurry stars and deep sky objects.

Seeing is typically better in places where the geography is very flat. The air masses moving over the land encounter few obstacles and flow more smoothly (sometimes called a laminar flow). In Florida, the winds coming over the mountains gets all mixed up like a creek flowing over big boulders, which makes for terrible seeing.
