If you count the cephalothorax as one body segment, how many major segments does an arthropod with a cephalothorax have?
Two
200
What type of symmetry does this have?

If an arthropod did not have any predators living in it's ecosystem, would it still need an exoskeleton?
Yes it needs it for the support of the body.
300
An organism with this symmetry can only be cut into two identical halves by a single longitudinal cut along the center-right and left halves. Human Body

300
These are divided into these three segments-
Thorax, Abdomen, and Cephalothorax

Repiration
500
The transfer of pollen grains from the anther to the carpel in flowering plants.
Pollination
500
Why do we say that arthropods are constantly bleeding internally?
They have an open circulatory system, and blood flows directly onto the tissue from the arteries
