In connell’s classic experiment on barnacle distribution, the realized niche of the larger species b (semibalanus) is smaller than its fundamental niche. connell demonstrated that biotic interactions limited the distribution of the smaller species a (chthamalus). the control consisted of removing both barnacle species from one half of each rock. only abiotic factors such as desiccation (drying out) stress influenced the distribution of both species. connell demonstrated that biotic interactions limited the distribution of the larger species b (semibalanus).

When analyzing tree rings, what do scientists assume a thin ring indicates?

Hormones are chemical molecules produced by endocrine glands. one such endocrine gland is the thyroid gland, which synthesizes the thyroid hormone, which in turn affects the heart muscles. which two statements describe the probable reason for the function of the hormone? the cells in the heart have specific receptors that allow for the intake of hormones. the heart and the endocrine glands have the exact same types of cells. all cells make the same types of hormones. thyroid hormones show their effect on the heart by means of specialized cells. thyroid cells and cardiac cells have different dna.
