Answer:
The periosteum is one source of precursor cells which develop into chondroblasts and osteoblasts that are essential to the healing of bone. Other sources of precursor cells are the bone marrow (when present), endosteum, small blood vessels, and fibroblasts.
The alternation of generations is an important concept in the evolution of plants. All land plants have alternation of generations. In mosses and their relatives (Bryophytes), the haploid gametophyte is the dominant generation, and the diploid sporophytes are sporangium-bearing stalks growing from the gametophytes.
Autotroph: a creature that obtains its carbon from inorganic carbon dioxide
Chemotroph: an organism that obtains energy from chemical substances-Heterotroph: an organism that must receive its carbon in an organic form
Phototroph: an organism that produces energy from sunlight
The term "primary nutritional groups" refers to a category of creatures that are separated into subcategories based on the sources of carbon and energy that they require for survival, growth, and reproduction. Carbon can come from organic or inorganic sources, and energy can be derived from either light or chemical molecules. ATP, carbs, or proteins are used to store the liberated energy as potential energy. The energy is eventually put to use for activities essential to life, like movement, growth, and reproduction.

Answer:
B. a bowling ball
Explanation:
According to Newton's law of universal gravitation every body attracts another body by an amount of a force that is directly proportional to the product of the two bodies' masses and inversely proportional to the square of the distance between them. Knowing this then, it becomes clear that the body with the biggest mass will exert the greatest gravitational pull. From this list the ball with the biggest mass will be a bowling ball.
