How are the segments of a crayfish different from those of an earthworm?

As opposed to earthworms, arthropods (crayfish) segments often become fused. Therefore, certain parts of a crayfish that looks like one piece, was once multiple pieces before they became fused together, so some segments were actually once more than just that one segment. An earthworm on the other hand, is just as many segments as are seen, and always has been.

Why do scientists think arthropods and segmented worms have common ancestor?
all arthropods have segmented bodies, just certain ones, have a round segmented body, and others have a flat segmented body.

How do the lower pelvic arteries in human differ from those in cat?
Lower pelvic arteries differ from human from those of a cat in many different ways from the way the cat and human can go through labor and how the human and the cat can carry the babies of kittens are very different.
The fact that offspring may have characteristics somewhat different from those of their parents is primarily due to?
meiosis.
What is best viewed under a microscope paramecium earthworm or grasshopper?
those are for two different kinds of microscopes. Electron microscopes would be for looking at the paramecium and dissecting microscopes would be necessary for the earthworm and grasshopper.
What is isotomic?
It is an imaginary line drawn through the same segments of the same limb in different animals, to indicate those segments which have the same relative position in each animal.
Do tape worms have scales?
No, they have segments and part of those segments are called setae.
How are the respiratory organs of the grasshopper different from those of the earthworm?
Respiration by the entire exterior versus by staggered openings is the way that the respiratory organs of the grasshopper are different from those of the earthworm. The annelid in question manages to take in oxygen and to release carbon dioxide as long as the outside of the worm's body is moist. The insect in question uses spaced holes, known as spiracles, to release carbon dioxide and to transport oxygen to the trachea.
What segment of the earthworm is the ovary found?
not what those guys said
You live in North America and your lawn doesn't drain well after a rain so you have crayfish holes in your lawn How do you get rid of the crayfish without having to capture them?
Create a different drain route for the water, or you can try to fill those holes with dirt. You could set up a seafood stand, if you have a permit or license for it! Crayfish is kind of nasty though This is an interesting problem I have never heard of before. But if your lawn is still flooded, another thing you can try is set a crayfish trap, which can be purchased from a local sporting goods store. This is how they harvest crayfish from commercial crayfish farms.

Are there any spiracles on the thoracic segments?
No, the only spiracles are on the abdominal segments. Those open up th large tracheal tubes.
Can parallel lines be a different size but still be parallel?
Yes; but in math, if you talk about "lines", that means one that stretches infinitely in both directions. If you are talking about limited-length "lines", those are called "segments".Yes; but in math, if you talk about "lines", that means one that stretches infinitely in both directions.

How are the antennae other walking legs and swimmerets related?
They are related because they all perform some part in the crayfish. Without those parts the crayfish will not survive.They are not related at all!!
Why can a deletion have a potentially catastrophic result?
Cause segments of genes are lost. This means that you can't get them back. Some of those segments could be vital for survival.
The faces of a polyhedron are the line segments connecting each vertex.?
Not quite. Those line segments are the lines which are the edges of the faces.
