Which statement describes a similarity between the calcium pump and the sodium-potassium pump? Both pumps move substances from h
igh concentration to low concentration. Both pumps only move substances into cells. Both pumps require no energy to function. Both pumps use proteins to transport substances across the cell membrane.
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.

such as tissue paper, do not allow light to pass through as easily, and images cannot be seen clearly. Opaque materials, such as wood and metals, allow no light to pass through.
Answer: In diploid stage the two spores fuse together to form a prothallus which is a diploid stage. Hence, the similarity in the reproductive cycle of fungus and a pteridophyte is that both organisms produce haploid spores and exhibit diploid and haploid stages
