Biology Lab Report on the Effects of Adrenalin on a Daphnia

Abstract For this experiment we tested the consummations of different epinephrin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a glide with cover slip in order to examine its twinkling by using the microscope. Aim In this Lab we allow for study the effect of different concentrations of adrenalin on the kernel rate daphnia, the piddle flea. It is expected to recognize a room access of the daphnia in its reaction the three different adrenalin concentrations, in hurt of heart rate. Background The endocrine gland dodging works with the nervous frame to regulate and coordinate bole functions. While the nervous system works quickly and sends messages direct to specific body parts, the endocrine system takes a long-lasting time to produce a longer-lasting effect. The system operates by relinquish chemical messengers called hormones into the racestream, which travel end-to-end the body. Eventually the hormone reaches a target organ or tissue to cause an effect. growth and development, sexual maturation and reproduction, transfiguration and homeostasis are some of the processes modulate by endocrine gland secretions. Endocrine effects butt last hours, days, or rase years. Adrenalin is a hormone secreted by the adrenal glands that helps the body megabucks with strain. It produces the emergency, or crusade or fight, response and is secreted when sudden stress such as fear, pain, anger, or extreme physical perspiration requires a pause of energy.

Adrenalin causes increases in metabolic rate, active rate, heart rate, blood pressure, swea ting and even blood clotting. It is a conven! ient hormone to study because its effect is relatively swift. Materials required Materials list daphnia culture, music dropper, slides, cover slips, bristles or threads, paper and pencil, paper towels, marine museum water, retrieval beaker, dropper bottles containing adrenalin in various concentrations, microscope. order 1) With a undress medicine dropper, remove a daphnia...
