You need to make 3 pies, one for NaCl, one for C6H12O6, and one for NaOH.

NaCl has two elements, Na (sodium) and Cl (chlorine).

C6H12O6 has three different elements, carbon (C), hydrogen (H), and oxygen (O).

NaOH has three elements, Na (sodium), O (oxygen), and H (hydrogen).

Researchers have noticed that some men who were sterile because their sperm cells were unable to move also had chronic infection
zimovet [89]

Answer:

Kartegener's disorder

Explanation:

The respiratory tract has cilia which move. Sperms also have a tail that moves. They both have the same protein in their structure called microtubules. There is a disorder in which there is the absence of a part in the microtubule. Dynein arms absent in microtubules. Because the respiratory system and sperm both contain cilia that's why these two systems have a connection and not work properly.

If the concentration of sodium is greater outside a cell than inside the cell, which process could move sodium out of the cell?
Papessa [141]
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.<span>

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplas
Marysya12 [62]

Answer:

Why are molecules such as valinomycin effective at transporting ions across the membrane?

Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.

Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?

Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.

Explanation:

Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
