Countercurrent exchange is evident in the flow of water across the gills of a fish and the blood within those gills. Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or component, between two flowing bodies flowing in opposite directions to each other. Biological countercurrent systems may be downhill exchanges and hairpin multipliers.
Answer:
Mendel saw purple flowers in the F1 generation, but both purple and white flowers in F2. How did this help him see that traits are inherited as discrete units?
Explanation:
Since the original parents were both purebred then it makes sense that both offspring are purple because of the purple flowers dominant allele.
In gluconeogenesis is synthesis of new glucose from noncarbohyhate precursors, provides glucose when dietary intake is sufficient.It is essential for regulation of acid base balance,amino acid metabolism and synthesis of carbohydrates.
It is the process of glucose synthesis. Glycoysis run backwards, three new reaction happen which involve new enzymes , make the standard free energy favorable. When every molecule of glucose synthesis from two molecules of pyruvate , 4ATP, 2GTP, 2NADH are used.
When the energy charge of the cell drops, the cell begins producing more ATP by glycolysis and turn off gluconeogenesis to conserve the ATP molecules.This process are stimulated and inhibited by similar allosteric effectors that bins to specific site on enzymes.

Answer:
its gonna be a line going up and down 4 to the left of the y axis (the line in the middle going up and down). Because no matter what y is, x is going to be -4. So you go over -4 and up and down all the way y don't matter
