One difference between a gastrovascular cavity and a complete digestive tract?

A gastrovascular cavity is a digestive sac with only a single opening. A complete digestive tract (otherwise known as an Alimentary canal) has two openings (a mouth and anus) between its digestive tubes unlike the gastrovascular cavity in which food is ingested and eliminated through the same opening (example would be hydra)


What would be the effect of running 3 phase single core supplies through separate steel openings?

You will induce a current into the steel surrounding each opening. It is, after all, a single turn transformer. That current will manifest as heat, and as a small loss of power. To prevent this, run all three conductors through the same opening, including the neutral conductor if there is one, and the net induced current will be zero. Alternatively, slot the side of the openings so that there is no complete circuit around each conductor.

How many holes are there on the bottom half of your body?

The male human body has two openings for the removal of waste products and for sexual reproductive purposes. The Female has three; however these would be considered major openings, whereas if you consider minor or microscopic openings (pores, sweat glands etc.) the number would be astronomical. There are three holes in a female: the anus for passing solid waste ("poo"), the opening of the urethra to pass urine ("pee"), and the opening of the vagina for sexual intercourse and childbirth.


How do you install the cpvc plumbing on the round single shower handles that twist in a circle?

On the back of the valve/diverter there are either four or three openings. One on either side for hot and cold water coming into the valve and one on top going up to the shower arm. If it is there the fourth opening is on the bottom and would go to the tub spout. Depending on the design you may have to solder adapters for the cpvc fittings into the openings of the valve.


Why do lungs have small external openings when large openings would let in more air?

There is an advantage to a smaller opening which is that it is easier to trap pathogens like fungal spores and bacteria. This is often cited as to why the lungs don't have openings with a shorter pathway that opens in the chest or back. Some pathogens are trapped in saliva or mucus in the throat but most of it is caught by the mucus in the trachea and bronchi.


What are two major differences among animals are?

If by animal you mean 'anything that respirates(oxygen)' then the two major subdivisions would be protozoic and metazoic. That is single celled and multi-celled. If by animal you mean 'Metazoic repirators(oxygen)' then the two major subdivisions would be protoastomes and dueterostomes. That is single opening to digestive tract and two openings to digestive tract. (With sponges forming a third branch that we will ignore for the sake of the two division criteria.)
