I believe the correct answer from the choices listed above is the first option. <span>The biodiversity and distribution of penguin species in the Antarctic Peninsula are changing as sea ice disappears. This is caused by the climate change which causes glaciers to melt down rising the sea levels. Hope this answers the question. Have a nice day.</span>
The physical location of a gene within the genome is called the Locus.
Answer:
The Na⁺/Ca²⁺ exchanger, which couples the movement of Na⁺ down its electrochemical gradient with the movement of Ca²⁺ against its electrochemical gradient, is a(n) <u>symporter secondary active transport </u>because Ca²⁺ and Na⁺ move in different directions across the membrane.
Explanation:
The Na⁺/Ca²⁺ exchanger is a secondary active transport because it uses the energy of the Na⁺ that moves in favor of its electrochemical gradient to bring a Ca²⁺ ion against its electrochemical gradient inside the cell. This transport needs the help of a symporter, which is a protein that moves two different ions in the same direction.
Can you provide the graph? I can't answer the question if I don't know what it is ^^
A.c.a for true and what else are u asking for
