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.

In recent years, there has been controversy among biologists about whether Neanderthals should be placed within the same species
Natali [406]

Answer:

The correct answer would be - biological species concept.

Explanation:

The biological species concept is a concept of speciation or how a species forms in nature. According to this, a species is the group of the population that can naturally or potentially interbreed with each other, not on the basis of their physical similarities or habitats.

The physical appearance could be useful as recognizing a species but not defining it. As neanderthals show very little or no gene flow with a modern human it means they do not belong to the same species as modern homo sapiens.

Thus, the correct answer is- biological species concept.
