Answer:
The digestive system!
Explanation:
The digestive system is made up of the digestive tract - a series of hollow organs joined in a long, twisting tube from the mouth to the anus - and other organs that help the body break down and absorb food.
Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine - also called the colon - rectum, and anus.
The answer would be: Endometrium.
Centrioles is only found in animal cells but not in plant cells.
Answer:
Both electron transport and a proton gradient
Explanation:
The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.
Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.
Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.
Thus, the selected option is correct.
