Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

The minerals are mostly characterized by the <u>Physical</u><u> </u><u>properties</u><u> </u><u>(</u><u>D</u><u>)</u> which includes the hardness, lustre, density etc. The mineralogists check the detailed view of minerals by using high powered microscope.
The minerals are chemical compounds which are formed as a result of physical processes or geological processes. They mostly occur in crystalline form. <u>For Example:</u> Cacite, Sulfur, Quartz etc

You need to recognize that the higher on the food chain, the fewer the number of organisms that occupy that level. This is because of the energy that is available from one level to the next has to decrease since it is used for life's processes.

Answer: Phagocytosis
Explanation:
Phagocytosis is the ingestion of cells or particles as a defence mechanism when white blood cells (macrophages) engulf foreign matter such as bacteria and viruses or as part of a digestion process in free-living cells such as amoeba.
