Biology Lab Report on the Effects of Adrenalin on a Daphnia

Abstract For this experiment we tested the consummations of different epinephrine concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its jiffy by using the microscope. Aim In this Lab we leave alone study the effect of different concentrations of adrenalin on the message rate daphnia, the piddle flea. It is expected to recognize a doorstep of the daphnia in its reaction the three different adrenalin concentrations, in hurt of heart rate. Background The ductless gland scheme works with the nervous frame to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to specific body parts, the endocrine system takes a long-acting time to produce a longer-lasting effect. The system operates by relinquish chemical messengers called hormones into the gillyflowerstream, which travel end-to-end the body. Eventually the hormone reaches a target orga n or tissue to cause an effect. offshoot and development, sexual maturation and reproduction, transfiguration and homeostasis are some of the processes correct by endocrine gland secretions. Endocrine effects poop 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 competitiveness or fight, response and is secreted when sudden stress such as fear, pain, anger, or extreme physical perspiration requires a break out of energy.

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