In biology, symbiotic nitrogen-fixing bacteria invade the root hairs of host plants where increment or multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. The bacteria that change nitrogen gas from the atmosphere into solid nitrogen usable by plants are called nitrogen-fixing bacteria. These bacteria are found both in the soil and in symbiotic relationship with plants.

Answer:
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The cartilage in the region of the epiphyseal plate next to the epiphysis continues to grow by mitosis. The chondrocytes, in the region next to the diaphysis, age, and degenerate.

Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food.
Explanation:
Answer;
can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes
The skin is permeable to organic solvents, such as acetone or turpentine, because they can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes.
Explanation;
-Human skin has a low permeability; that is, most foreign substances are unable to penetrate and diffuse through the skin. Skin's outermost layer, the stratum corneum, is an effective barrier to most inorganic nanosized particles
