Abiologist is comparing the growth of a population of flies per week to the number of flies a lizard will consume per week. she has devised an equation to solve for which day (x) the lizard would be able to eat the entire population. the equation is 3x = 5x - 1. however, she has observed that the lizard cannot eat more than seven flies in one week.

explain to the biologist how she can solve this on a graph using a system of equations. identify any possible constraints to the situation.

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.
