Answer choice A. or Controlled variables, Answer choice B. or Manipulated variables, and Answer choice D. or Control groups are a part of what's found in a controlled experiment. (D.) Control groups are a part of what's found in a controlled experiment. Therefor this only leaves one answer and that answer is Like I said C-None of these are found in an observational study.

Explanation:
One of the edocrine processes the kidney is involved in is called the RAAS (Renin-Angiotensin-Aldosterone System) which is a signaling pathway involved in blood pressure control. It involves a number of hormones:
Angiotensinogen is produced by the liver in response tovarious inflammatory proteins
Renin is a protease produced by the kidneys in response tohypotension,
Angiotensin II increases blood pressure via a number of mechanisms:
Aldosterone acts to increase reabsorption of Na+ and water and increase elimination of K+ and H+ in the distal tubules of the kidneys for ion concentration maintenance
Answer:
Explanation: Malate regenerates oxaloacetate by action of NAD+-dependent malate dehydrogenase, completing the cycle. Coenzymes including FAD and NAD+ are reduced in the Krebs cycle, which transfers electrons by the electron transport chain with oxygen as the final acceptor.
