Transport of Na+ from a place of low concentration to a place of higher concentration. <u>This is the right answer.</u>
<u />
The sodium-potassium pump is the most common and well-known example of active transport. At the cell membrane, the sodium-potassium pump moves 3 sodium ions out of the cell and two potassium ions into the cell per ATP. Examples of active transport include the uptake of glucose in the human intestine and the uptake of minerals and ions into the root hair cells of plants.
One of the greatest examples of active transport is the movement of calcium ions out of cardiomyocytes. Cells secrete proteins such as enzymes, antibodies, and various other peptide hormones. Amino acids are transported across the intestinal mucosa of the human intestine. The movement of ions or molecules across cell membranes to regions of a higher concentration is assisted by enzymes and requires energy.

When the surface of a mineral reflects light in manner that is similar to a metal, the mineral is said to have a <u>metallic luster.</u>
Explanation:
A mineral is a pure, naturally occurring, solid chemical substance. They have a crystalline structure and a definite chemical composition.
Another physical property that can be used to define a mineral is luster. It can be of two types: metallic luster and non-metallic luster.
A mineral is said to have a metallic luster, if it has high reflectivity like a metal. Examples : pyrite, galena.
