Hormones are chemical substances produced in one organ that are released into the bloodstream and affect the function of a target organ. which of the following conditions is required for the target organ to respond to a particular hormone a) modify its plasma membrane to alter the hormone entering the cytoplasm b) be from the same cell type as the organ that produced the hormone c) experience an imbalance that disrupts its normal function d) have receptors that recognize and bind the hormone molecule

D

Explanation:

Receptor are special protein found on the surface of certain cells that form HRC hormone receptor complex

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
