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.
A higher temperature gradient causes faster heat transfer, and thus faster convection currents. If the core were cooler, the temperature gradient would be lower, so the convection currents would likely slow down.

Answer:
Matter is mass, Element is matter, and Atom is element.
Explanation:
Matter is anything that has mass or takes up space (Volume). Matter is made of elements. Elements such as carbon dioxide or gold. An atom is the smallest unit of matter. Elements are made of atoms. Atoms are what chemically makes an element. :) Hope she gets her phone!
