Answer:
2, that’s what the 2 means.
Explanation:
The answer is
C. The way the layer interacts with the layer below it.
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.
1)Without photosynthesis: If we didn't have plants, algae and bacteria to do the photosynthesis, CO2, a air pollutant wouldn't be converted in to glucose for those organisms and there would be no more Oxygen released to the atmosphere. Less photosynthesis means less oxygen production and many organisms, like us, would die.
2)Without cellular respiration: Without this process we couldn't convert our food into the energy, ATP, necessary for the cells to function properly. Plus, this process also forms water, and without it, it would be another reason for the death of the cells.
Ultimately, will cause the death of the aerobic organism.
