Explanation / Answer

live bearing -> chorion (birth giving and not egg laying)

madreporite -> seive plate

claspers -> sex fins (part of male pelvic fins of sharks or rays under which they hold the female for copulation.)

neotenic -> gills retained in adult amphibians (morphological structures retained by adults)

allantois -> membrane that collects metabollic wastes (fluid filled membrane in womb which help in gaseous exchange and removal of liquid wastes.)

plastron -> ventral shell of turtle ( flat part of a turtle's shell at the ventral side)

precocial - > ready to move at birth (young one is ablie to fee itself just after getting born/hatched

omnivorous -> can eat anything (i.e eat plants as well as animals)

amphiartherosis -.> slightly moveable joints (eg. intervertabral disc)

diartheosis -> freely moveable joints (eg. in limbs)

perietal pericardium -> fibrbous outer pericardium (outer heart layer)

hematopoeisis -> gives rise to blood cell (process of forming blood cells from stem cells in the bone marrow)
