Answer:
Tendon sheaths <u>act as friction-reducing structures.</u>
Explanation:
Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.
The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.
The answer is Over-the counter.
Over-the-counter are medications sold without prescription. They got their name they are passed over the counter from the pharmacist to the patient. However, they, together with prescription and illegal drugs, are able to change the central nervous system.

<span>Els moduladors al·lostèrics que actuen en els humans són el 2,3-Bisfosfoglicerat (2-3-BPG),el CO2
i els H+
. El 2,3-BPG s'uneix al centre del tetrà mer de l'estat T i aixà l'estabilitzà launió per interaccions iòniques. Els protons actuen perquè quan el pH és baix l'hemoglobinadisminueix la seva afinitat per l'oxigen (efecte Bohr). L'augment de la concentració del CO2
té el mateix efecte perquè el CO2 es combina en H2O i es dissocia en HCO3-i H+
i per aixòdisminueix l'afinitat de l'hemoglobina perquè augmenta la concentració de protons</span>
Photosynthesis is endergonic (needing energy) because in the process OF photosynthesis, these plants use sunlight and carbon dioxide and water to make glucose which is sugar. It's taking substances to make the energy it needs.
