Sodium ions, oxygen (O2), and glucose pass directly through lipid bilayers at dramatically different rates. Which of the followi
Elodia [21]

Answer:

The correct order, from fastest to slowest, for the passage of molecules and ions through the cell membrane is oxygen, sodium ions, glucose (option D).

Explanation:

The plasma membrane is a lipid bilayer, with glycoproteins and membrane proteins, which constitutes a semi-permeable barrier to the passage of substances into and out of the cell.

The speed with which a substance can pass through the membrane depends on its chemical properties -hydrophilic substances pass through with greater difficulty than lipophilic ones- requiring in some cases specialized transport mechanisms. The different rates with which a substance passes depends on this.

  • <em>Oxygen (O₂) </em><em>passes through simple diffusion, depending on a concentration gradient. It's the molecule that passes through the membrane the fastest. </em>
  • <em>In second place, there would be the </em><em>Na⁺ ions</em><em> -charged atoms- that cross the membrane by facilitated diffusion, through specific ionic channels. </em>
  • <em>The </em><em>glucose</em><em> molecule, being larger, requires the use of transport proteins, being its passage through the membrane slower with respect to oxygen or sodium.</em>

Undoubtedly, molecular weight and affinity for the plasma membrane are determining factors for the passage of molecules through the lipid bilayer.

Explain why a natural ecosystem is both an open system and a closed system.
kotykmax [81]

Answer:An open system exchanges matter and energy with its surroundings (for example, an ecosystem). ... Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example,the water and nitrogen cycles, approximate to closed systems.Sep 18, 2020

A population is growing exponentially what can you conclude
storchak [24]

Answer AND Explanation:

Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:

  • An increase in number of cells dividing following a geometric progression.
  • Cells having adjusted to the new environment.
  • Food and other factors are not limiting hence cells are not competing for resources.
  • The rate of cell increase being higher than the rate of cell death.
