Diagram A correctly shows the movement of materials by osmosis.
- Osmosis can be defined as the net movement of a fluid (e.g., water) across a semipermeable biological membrane.
- Osmosis movement is due to different concentrations of one or more solutes on both sides of the cell membrane.
- Osmosis does not require energy to move substances across the membrane.
In conclusion, Diagram A correctly shows the movement of materials by osmosis.

Answer:
The correct option is a. Fibrocystic breast disease refers to the progressive development of fluid-filled cysts and fibrous tissue.
Explanation:
Fibrocystic breast disease is characterized by benign (non-cancerous) changes in fibrous tissue. These changes may include irregular lumps or cysts (Breast cysts are sacs full of fluid inside the breast) which tend to mix with the surrounding fibrous tissue, breast swelling, nipple tenderness. Fibrocystic breasts are composed of tissue that can have a lumpy or rope-like texture. Which is called "nodular or glandular breast tissue" in it, there are observable characteristics of the disease through the microscope as: a prominence of fibrous tissue, excessive growth of the cells lining the breast ducts, enlargement of the mammary lobes and the fluid-filled cysts.
Epstein (1965) presented observers that photographs of a quarter, dime, and half-dollar were all equal in physical size. The photographs were at the same distance from the observers. Using only one eye the observer said that <span>the dime was closest, the quarter was farther than the dime, and the half dollar was farthest of them all. Using two eyes this was not the result, because they were aware of the distance. So, t</span>his Epstein's results showed that familiar size is most effective when other information about depth is absent.
