The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

Effects of Caffeine and Nicotine on Lumbriculus variegatus INTRODUCTION An experiment was conducted to study and explore the circulatory system by exposing Lumbriculus variegatus‚ black worms‚ to household drugs. Lumbriculus variegatus was chosen as the experimental organism because of their transparent bodies and their simple physiology. Their transparent bodies help the experimenters to easily see their pulse. Another reason for choosing this specific organism is their body structure—large

1. Do you agree with the FDA that nicotine can be classified as a drug and that cigarettes can be classified as devices under the definitions in the Food‚ Drug and Cosmetics Act? I agree that nicotine can be classified as a drug because it falls into the categories of the three clauses (A)‚ (B)‚ (C) and (D) under the definitions in the Food‚ Drug and Cosmetics Act: - It is article recognized in the official U.S Pharmacopoeia (Clause A) - It is article that intended for use in the diagnosis

example of a heart rate is called resting heart rate. The resting heart rate of the body is the number of contractions of the heart that occur in a single minute while the body is at complete rest. The resting heart rate can differentiate upon age‚ gender‚ and health of a human. There will also be a difference in number upon the resting heart rate of athletes and a non-athletes. I calculated 68 beats per minute for my resting heart rate. Another example of heart rate is target heart rate. Mathematically

the experimental hypothesis was accepted. These findings could be due to the negative phototactic response that occurs when they are exposed to visible light that are above 600 Mn (nanometers) that are also considered the color red. This shows that Daphnia have a greater phototactic reaction to red light than when exposed to white light. When compared to a similar study‚ the same result was found. It was reported that there was a significant difference in the Daphnia’s phototactic reaction when exposed

different adrenalin 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 heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart rate. Background The endocrine system works with the nervous
