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

Explain how the three hormones involved in insect growth— ecdysone, juvenile hormone, and PTTH—interact in molting and metamorphosis.
You 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.
Explain the action or effect of moult-inhibiting hormone in insects development (exclusively in mosquitoes).

- 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_forwardHormones are signaling molecules that can alter cellular activity and gene expression.
