Explanation:
RNA consists a ribose sugar while DNA consists deoxyribose sugar. Cellulose and lactose are not the components of DNA of RNA. Uracil is a nitrogenous base that is present in the structure of RNA.
Other than sugar, these molecule consist of nitrogenous base and a phosphate group.
The earth's crust varies in many places. in some areas, there are different variations of high elevation (such as ocean trenches), and low elevation (such as volcanoes ie. hawaii)
Most articulating bones are covered with thin layers of articular cartilage.
Articulating bones are connected via synovial joints. This means that the articulating extremity of each bone will be contained in a synovial capsule. This capsule will contain a fluid necessary for healthy and mobile articulations, commonly referred to as synovial fluid.
The <u>opposing surfaces</u> of bones that are connected in this way contain a thin layer of articular cartilage. This cartilage, along with the presence of synovial fluid, allows bones to <u>move smoothly along one another and prevents harm to the actual bone tissue.</u>
