Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.
Their children would have AA,BB, or AB blood types. it is a 25% chance of AA, a 25% chance of BB, and a 50% chance of AB so most likely their child's blood type would be AB.
The overall function of the digestive system as digestion and absorption of food stuffs, and the general activities of each digestive system organ is; Ingest, digest, absorb, defecate.
Ingestion involves placing food into the mouth, propulsion involves propelling food from one organ to the next using peristalsis. Mechanical digestion involves the physical fragmenting food into smaller particles. Chemical digestion refers to breaking down food molecules to building blocks by enzymes. Absorption is the transport of digested end products to blood or lymph; and finally Defecation which involves the elimination of indigestable material from GI tract by anus.
You have rods and cones in your eye. Cones detect colour and fine detail. Rods are used for monochrome vision; usually, monochrome vision is used in poorly lit, dark environments. Rods and cones are both in the retina of the eye.
Cones = Colour. CC is a good mnemonic.
