B it's a vegstigial trait
Many biology texts today still refer to the appendix as a vestigial organ
It’s actually called anaerobic cellular respiration because you’re not using oxygen. For example, when you sprint you can’t breathe very well, so you’re not inhaling as much oxygen you need to make that energy for you to move. Your muscles will go into lactic acid fermentation, and the result of that is energy (ATP) along with lactate (lactic acid), and you will probably start feeling pain as the lactic acids build up.
Hope that helps!
An estuary is partly enclosed coastal body of water with one or more rivers flowing through it, and with a free connection to the open sea. it would be more of a collection. hope this help have a great day.
