Paronychia might be the answer
Trying to determine whether a fossil is a human ancestor, we should always look for skeleton or bone that make us human today.
<h3>What is bone?</h3>
Bone is a connective tissue which is metabolically active and the main function of bone is to provide mechanical or structural support as well as perform movement, and protect important organs of the body.
The bone is made up of bone cells known as osteocytes and extracellular matrix. The total number of bone human body contain is 206 bones including bones of spine, legs, arms, ribs, and skull.
Bones are made up of calcium and carbonate and they have bone marrow in which blood cells are produced. By nature bones came in category of living and they are active tissue .
There are several types of bones such as flat bones, short bones, sesamoid bones, and long bones. The function of bone is to protect vital organs of the body.
Therefore, trying to determine whether a fossil is a human ancestor, we should always look for skeleton or bone that make us human today.

For walking, a group of four muscles, known as Quadriceps muscles are the most important. A complete bed rest for a longer period of time causes the reduction in the flexibility of the quadriceps. So, in order to prepare a person for ambulating after a long bed rest, the nurse should focus to restore the flexibility in the quadriceps. This can be done by alternating flexing and relaxing the quadriceps. This exercise would help in reviving the strength of the quadriceps.
Diffusion is the movement of particles from a high concentration area to a low concentration area.
Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane.
Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.
