Answer:
Friction depends on the coefficient of friction which in turn depends upon the nature of the surface. Hence, this statement
is false.
Answer:
Explanation:
A. False - A symporter system requires that one of the molecules to be transported using passive transport.
B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.
C. False - sucrose moves through ion channels not by diffusion to better control its movement across the membrane.
D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.
E. False - One of the molecules needs to be moving against its concentration gradient.
F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.
I think the correct answer would be diarrhea. It is often a result of consumption of contaminated food and drinks. And each year, it was estimated that approximately 2 million children died due to this. It is a condition where bowel movements are frequent and is in liquid form which would lead to dehydration.
