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.
Answer:
The answer is B
Explanation:
In the text, Frederick makes it clear to us the silver trump not only inspired the slaves, but him also. He couldn't see the trump without looking at it. He couldn't hear the trump without listening to it, and he couldn't feel the trump without feeling it either. [ i hope this helped :) ]
Answer: D. Acid from abandoned mines
Explanation:
Point source pollution can be define as the pollution that can be caused by a pollutant whose source of origin is known. As the source of origin is known the path of the pollutant can be traced back to it's origin hence, the pollution can be controlled.
Among the options given, D. Acid from abandoned mines. is the correct option this is because of the fact that the source of origin of the pollutant is known that is abandoned mines.
Tissue is a group of cells that have similar structure and that function together as a unit. ... There are four main tissue types in the body: epithelial, connective, muscle, and nervous. Each is designed for specific functions
Drawn bow because the flexing of the bow and the increased tension in the bow string contain the energy expended by the archer’s muscles transferred to the bow. The energy is transmitted to the arrow when then it’s released. All this is mechanical energy.
The other items in the list have potential electrical energy (battery), locked energy in the nutrients released during digestion (bun), electromagnetic energy (sun).
