Diffusion is the process by which gases such as oxygen and carbon dioxide cross the plasma membrane.
Further Explanation
Plasma membrane present in all the animals and plant. Plasma membrane in plants is covered by a cell wall. plasma membrane is made up of lipid bilayer which is semipermeable to some molecule ions and gases. Through this lipid bilayer, plasma membrane regulates the influx and efflux of a molecule.
Main functions of plasma membrane is to,
• Maintain the structure of a cell
• Help in interaction with other cells
• Provide protection from outside
• Help in transport nutrient in the cell and transport toxic substances out of the cell.
The lipid bilayer is made up of phospholipids and these are an amphipathic molecule that contains hydrophilic as well as the hydrophobic region. the plasma membrane has 2 bilayers closely packed together and interior of membrane is hydrophobic,altogether these structures make plasma membrane selectively permeable and allow flux of small non-polar material like carbon dioxide, oxygen through simple diffusion.
Diffusion is a movement of a small molecule from higher concentration to a lower concentration. For example, oxygen is used by our cell very easily during metabolism and concentration of oxygen in cell become less and concentration of oxygen is high outside, so oxygen can easily diffuse through bilayer into the cell cytoplasm.

Why are the gas planets also known as Jovian planets? :))
Answer: because they're bigger planets
Explanation:
They have a larger mass so therefore they're called jovian GIANTS
B) intellectual disability
C) a mutation in his offspring
D) a change in his somatic cells
The germline mutation is heritable variation in the lineage of germ cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell (man's gamete) but not in a body cell. If present in the sperm cell, after fertilization with an egg cell, the mutation will be present in formed zygote. So, man's offspring will have the mutation
B. lightweight.
C. large.
D. sweet and fleshy.
Answer:
Option B, lightweight
Explanation:
Wind basically carries away the seeds which are light weight and winged which makes them peculiar to fit in the criteria required for floating. For example seeds of swan plants and cotton wood are light weight and also have some feather like bristles which allow them to be carried away by wind to a longer distance.
Water also carries light weight seeds as they can easily float on the water for example seeds of mangrove trees.
Thus, Option B is the correct answer
