A new study suggests these tectonic plates control their own speed more than the mantle does. ... The velocities of these plates and the velocities of the boundaries between these plates vary significantly on Earth.
Bones contain three components that in itself make it strong and flexible. They are collagen, calcium phosphate, and living bone cells. Collagen gives bones their structure, calcium makes bones strong, and cells generate more bone cells to fill up weakened parts. Calcium intake from food supplements and milk are also good for the bones because it can strengthen them more and make the skeletal system protected from bone irregularities and problems while growing. Vitamin D is essential for the absorption of calcium in bones. In order to offer support to the muscles and tissues of the body, bone growth is very crucial, because a weak bone cannot make the body function well. Comments Report

Answer:Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
triglycerides- fat
phospholipids- plant and animal cell membrane
sterols- plant and animal cell membrane's microorganism.
Explanation:
The best answer is D.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across a plasma membrane without using the cell's energy . The energy is provided by the concentration gradient i.e. molecules are transported from higher to lower concentrations, into or out of the cell.
Glucose binds to carrier proteins of the GLUT family. Once bound, the change shape so as to fit in the membrane channels and thus they translocate the glucose molecule from one side of the plasma membrane to the other.
