In the case of two competing barnacle species, the larger species Semibalanus is able to eliminate individuals of the smaller species Chthamalus through interference competition over its entire fundamental niche by overgrowing or dislodging them as they grow larger. Which of the following could be an explanation (reasonable hypothesis) that is sufficient to fully explain why Chthamalus evades competitive exclusion within the high-tide zone? Select one: a. The fundamental niche of Semibalanus extends over the entire tidal zone (both high and low-tide). b. Semibalanus is outcompeted by Chthamalus in the high-tide zone. c. The high-tide zone is outside the range of tolerance for Semibalanus. d. Chthamalus is competitively excluded in the low-tide zone. e. The fundamental niche of Chthamalus extends over the entire tidal zone (both high and low-tide).

There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. take for example the cells that line the digestive tract. these cells must be frequently replaced because they are constantly eroded by the movement of food through the tract. what mechanism(s) is/are in place to ensure that these cells are exact copies of the mother cell
