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:
F stands for feather R stands for red and W stands for white.
Explanation:
Answer:
C; Carbon dioxide concentrations increase with depth due to less uptake and decomposition of organic matter at depth.

Answer:
Because plants decrease the amount of CO2 in the air. By decreasing the plant population you decrease the amount of CO2 that can be removed.
Hydra reproduce through a process called budding, where a tiny knob-like structure begins to grow. As it continues to grow, it falls off, producing a new hydra.
