chromosomes includes one chromosome from each parent. The 46 chromosomes in a human somatic cell are two sets of 23 one from the mother and one from the father. A diploid cell (2n) has two sets of chromosomes. For humans the diploid number is 46 (2n=46). 4) Meiosis is the production of gametes that result in one set of chromosomes in each gamete. Gametes fuse to form a diploid zygote that divides by mitosis and develop into a multicellular organism. 5) Mitosis and meiosis are alike in the respect that

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized
