Chapter 44, Problem 1IQ
Summary Introduction
To explain: The way Juvenile hormone affects insect life as it is also used as an insecticide.
Introduction: Insects have soft bodies with a chitinous exoskeleton. Insects have an endocrine system producing hormones. Hormones are chemicals messengers that are produced and circulated in the blood to regulate behavior, physiological, and

- How do hormones compare structurally and functionally in invertebrates and vertebrates?arrow_forwardWhat are four actions of hormones in invertebrates?arrow_forwardYou are studying the arthropod molting hormones. Your experimental organism is the silkworm. You are conducting a series of experiments. In the first experiment you decide to experimentally decrease the production of the ecdysone by inhibiting the activity of the prothoracic gland during the first instar stage while maintaining the production of the juvenile hormone at normal levels. In the second experiment, you decide to maintain the ecdysone level normal and spray the first instar with juvenile hormone. Predict the results of your two experiments.arrow_forward

- Peanut and tree allergies are on the rise in modern, industrialized countries. Exposure to a protein in the nuts causes sensitive people to react with skin hives, reddened skin, breathing problems including the closing of the throat (anaphylaxis), and even heart attack. Much like a mosquito bite or other insect bite, this is all mostly due to the actions of one hormone in particular. 1) What hormone triggers this reaction? 2) Why does it cause swelling/closing of the throat/airways? 3) How does it change or impact the heart rate and/or blood pressure to life-threatening levels?arrow_forwardPart 1: The hormones listed below all play a key role in male reproduction: A) Follicle Stimulating Hormone (FSH) B) Luteinising Hormone (LH) C) Testosterone Explain the function(s) of these hormones giving reference to: their origin (where they made and released from), their target (cell, tissue, or organ), their stimulatory effects, and where relevant, their inhibitory effects. Part 2: The hormones listed below are each involved in the female menstrual cycle: A) Follicle Stimulating Hormone (FSH) B) Luteinising Hormone (LH) C) Oestrogen D) Progesterone Explain the function(s) of these hormones during the different stages of the menstrual cycle (starting from the point of menstruation). You should consider the following; • their origin (where they made and released from), • their target (cell, tissue, or organ), • their stimulatory effects (and where relevant) their inhibitory effects. • when during the menstrual cycle, their concentrations peak.
