I'd say first question, "life changes over time".
Second question, "when there are physical similarities in the early stages of embryonic development, it suggests that each of the modern organisms once had a common ancestor".
Third, appendix.
Fourth, "they are evidence that all came from a common ancestor and that life changed over time for all these organisms to exist".
Fifth, "they all share at least 50% of the same DNA arrangement".
I might be a little late but hopefully this helps!
Cnidarians uses arm-like parts called <u>tentacles</u> to sting.
Explanation:
Animals belonging to genus Cnidaria use arm-like structures called tentacles to sting. The cnidarians tentacles are present with specialized stinging cells called cnidocytes.
These cnidocytes are responsible for the stinging action which is done by the cnidocyte organelle called the nematocysts or the stingers.
Nemotocyts contain coiled thread or barb-like or hair-like structures which fires the toxin out while stinging.
The opening or the mouth-like parts on the tentacles contain numerous cnidocytes which releases toxin when the tentacles are touched by another organism or when the cnindarian touches its prey.
Glycolysis, the first process in cell respiration, produces four ATP, but it uses two of the ATP molecules, therefore producing a net two ATP molecules. The process also has two molecules of NADH.Glycolysis begins with glucose and breaks it down into two molecules of phosphoglyceraldehyde.
