What is the purpose of heart rate monitors?
Heart rate monitors are used to monitor heart rate on a longer-time basis. You can buy heart rate monitors between £10-500. You can use them whilst you are exercising so that you avoid the risks of exceeding your maximal heart rate.
How different types of music effect on heart rate?
Different types of music can affect heart rate in various ways. Upbeat and fast-paced music can increase heart rate and blood pressure, while slower, calming music can help reduce heart rate and promote relaxation. Personal preferences and emotional connections to music can also influence how it impacts heart rate.
How do you find steady state heart rate?
To find steady state heart rate, subtract your age from 180, that's steady state. For example, 25 year old's steady state would be 155. This isn't 100% accurate, the best way would be to use lactate samples; however, this is the most practical.
How can the heart rate be temporarily disrupted from its equilibrium?
Heart rate can be temporarily disrupted from its equilibrium by factors such as exercise, stress, emotions, caffeine consumption, or certain medications. These factors can either increase or decrease heart rate from its resting state.
How is cardiac output calculated?
Cardiac output is calculated by multiplying the heart rate (number of heartbeats per minute) by the stroke volume (amount of blood ejected by the heart with each beat). The formula is: Cardiac output = Heart rate x Stroke volume.
What is the effect of alcohol on the heart rate of daphnia?
alcohol will lower the heart rate of a daphnia depending on the quantity
Does sugar effect a daphnia heart rate?
yes it does
Relationship between temperature and daphnia heart rate?
As temperature increases, the heart rate of Daphnia generally increases as well. This is because higher temperatures can lead to an increase in metabolic rate and enzyme activity, causing the heart to beat faster to circulate oxygen and nutrients throughout the body. However, there is an upper limit to this relationship, as extremely high temperatures can eventually become detrimental and even fatal to Daphnia.
Design an experiment that students can perform to verify the prediction that coffee will increase heart rate in daphnia?

Why does the Daphnia's heart rate increase when placed in nicotine solution?
beacues its a stimulant.
How does caffeine affect daphnia heart rate?
it makes it go up then down then up then down... like a rollercoaster! :D
2 If the Daphnia heart rate experiment were performed on an endothermic organism what results would you expect?
Nothing will happen. This is due to the endothermic circulatory system which regulates and maintains a stabilized temperature.
How do you think depressant would affect the heart rate of daphnia?
Caffeine is a drug that stimulates the body and causes increased amounts of stimulatory neurotransmitters to be released. At high levels of caffeine consumption it can and has been linked to restlessness, insomnia and anxiety, this therefore causes raised stress and blood pressure, thus, increasing the heart rate.
How many times does a daphnia's heart beat on average?
180 beats per minute
Do daphnia eat hydras?
No, Daphnia can not eat Hydra, Because the Hydra has tentacles to capture the Daphnia and eat it. The Daphnia therefore can not get free which means the Hydra can eat the Daphnia. The Hydra therefore has more force and can eat the Daphnia. Your answer is NO.
What has the author Dorothy Wilson Kirk written?

What are adaptations of daphnia?
Daphnia are cold-blooded animals, and they do not thermoregulate. This means that their body temperature is the same as the water they are floating in. The chemical reactions that occur in the cells of Daphnia are dependent on certain enzymes, or proteins, to help the reactions proceed. As you increase the temperature of the water, the metabolism of the Daphnia increases as well, because chemical reactions occur faster at higher temperatures. This means that the heart rate will speed up in order to provide oxygen to the cells as the metabolism increases. However at 40 degrees Celsius, the enzymes break down, and the chemical reactions can no longer occur, so metabolism stops and the Daphnia dies
