Answer:
Diarthroses are freely movable joints.
Explanation:
Rheumatology may be defined as the branch of medicine that mainly deals with therapy and diagnosis of the rheumatic disease. The individual specialized in this field is known as rheumatologist.
Diarthroses joint is also known as synovial joint and lined in continuous with the periosteum of the joined bones. The synovial fluid is filled in the synovial joint. The synovial joints provide the free movable joints that allow abduction, extension and adduction of the body parts.
Thus, the correct answer is option (d).
Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
The process is called translation. Hope this helps!
I think its D because it requires more force to push something over a greater distance...but i could be wrong...
Hope this helps! Please correct me if I'm wrong :)
