Explanation:

Cell Structure

Creatures in kingdom Animalia are all multicellular organisms with eukaryotic cells that have nuclei and organelles. Unlike plants and fungi, animal cells do not have a cell wall. In addition, with the exception of sponges, cells are divided into specialized tissues or organs.

Movement

All Animalia members are mobile at some point in their lives. Motion is achieved through the musculoskeletal system and is one of the factors that allow animals to live in diverse ecosystems including oceans, mountains and deserts. Movement is achieved in various ways including legs, fins and wings.

Food and Respiration

All members of kingdom Animalia are "heterotrophs." They obtain nourishment from other organisms and digest the food internally. In addition, animals utilize aerobic respiration for cellular energy and food breakdown on a molecular level. Oxygen works at a molecular level to complete the metabolic processes necessary to turn fat and sugar into energy for the cells.

In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. ... After death, decomposition releases carbon into the air, soil and water.

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.

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

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