i said Oxygen but my teacher said it was wrong need help

Answers

Answer 1
Answer: Oxygen is the final electron acceptor in the electron transport chain in aerobic respirationThe electron transport chain of the mitochondria is the means by which electrons are removed from reduced carrier NADH and transferred to oxygen to yield water.In the cytochrome oxidase complex of the electron transport chain, four electrons interact with a molecule of oxygen and eight hydrogen ions. The four electrons, four of the hydrogen ions and the molecule oxygen are used to form water molecules.In anaerobic respiration the final electron acceptor can be of many types such as Ferric iron which is used by denitrifying bacteria

Which part of the kidney serves as the outer layer of fat that gives kidneys their shape?

Answers

Answer:

Renal Capsule

Explanation:

Externally, the kidneys are surrounded by three layers. The outermost layer is a tough connective tissue layer called the renal fascia. The second layer is called the perirenal fat capsule, which helps anchor the kidney in place. The third and innermost later is the renal Capsule.
Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.
