Answer:
The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.
Explanation:
You have to think of it as outside vs inside the cell.
Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration. Energy keeps the ions going from the way they would naturally happen.

Answer:
Lake A: pH = 4.5; Lake B: pH = 7.5
Explanation:
I think that one because if you look on the acid vs base chart acid is from 0-6 and bases are from 8-14 and acids are less toxic, so you would infer that lake A has acid and lake B has bases.
i would have picked the ones closest to 7 ,which is neutral, but I'm not sure that a base can be lower then 7 so I didn't pick answer C
Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>
