The term is Facilitated diffusion.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.
The energy is provided by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell.
The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.
Red blood cells use facilitated diffusion to absorb glucose.

Answer:
D. Lactose is absorbed intact and transported through the portal vein to the liver.
Explanation:
Lactose is a disaccharide. It is a sugar composed of galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose as a disaccharide can never be absorbed just like that. It needs to be broken down into monosaccharides first.

Why do melting ice caps make Earth warmer?
The correct answer is C. Albedo decreases.
When the albedo is lower, more radiation from the Sun gets absorbed by the planet resulting in rise of temperature. When the snow covered area warms up and melts, the albedo goes down and more sunlight is absorbed in that area and the temperatures increase.
