iris [78.8K]

Answer:

A.  passive transport by diffusion

Explanation:

Diffusion and osmosis are both types of passive transport. They do not require energy. Diffusion is the general term for the process. Osmosis is the diffusion of water molecules.

Many small, uncharged molecules can cross the cell membrane by diffusion. Oxygen and carbon dioxide are examples of two small molecules that pass the cell membrane by passive transport.

Larger or charged molecules require energy to cross the cell membrane. This is achieved by active transport.

The appearance of a pebbly texture on the surface of a deep wound indicates what process is taking place?
irakobra [83]
In a deep wound, there might be a few layers of tissue that need to be rebuilt because they were lost. In this rebuilding process this pebbly texture can be seen and it indicates that granulation is taking place (that's the process). Granulation is when small blood vessels and capillaries start to develop vertically to the outside part of the wound, being supported by connective tissue, and surrounded by cells of many other types for different purposes, such as immunitary functions or specialised tissue functions. This tissue growing is characteristic of healing and it presents this granulated/pebbly texture to it.
