Answer
Creation of species which can resist disease and tolerance to harsh environmental condition like drought
scientific theory consists of one or more hypotheses that have been supported through repeated testing. Theories are one of the pinnacles of science and are widely accepted in the scientific community as being true. A theory must never be shown to be wrong; if it is, the theory is disproven. Theories can also evolve. This doesn’t mean the old theory was wrong. It just wasn’t complete.
Answer:
The biological activity of an enzyme depends mostly on its tertiary structure.
Explanation:
Enzymes are proteins, specifically, globular proteins, this means that they have a ball-like shape. Every enzyme has an active site that ensembles with its substrate. The union of the substrate to the enzyme depends on this active site. If this union didn't occur, the enzyme wouldn't have biological activity. The active site is formed by the folding of the protein or what is called "tertiary structure". Therefore, the biological activity of an enzyme mostly depends on its tertiary structure.
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.
