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.
What is the advantage and disadvantage of increased pulse rate?
If you have an increased pulse rate it means that you are exercising you heart more often meaning that you have a chance of living longer because your heart is stronger but if you over work your heart then you will risk heart failure (if you have a weak heart)!
Can the heart slow down or stop?
Yes. Using a technique called "bio-feedback", it is possible to learn to control (within limits) your heart rate. Your heart rate naturally increases during times of excitement or vigorous exercise, such as running. Your heart rate will naturally decrease when you are relaxed and tranquil, and even more when you are asleep. If your heart stops, you will be dead.
When is your breathing likely to slow down?
when your heart rate slows down
How is cardiac output calculated?
It's the stroke volume times the heart rate.
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
Relationship between temperature and daphnia heart rate?
The higher the temperature, the faster the heart rate of the Daphnia. The lower the temperature, slower the heart rate of the Daphnia.
Does sugar effect a daphnia heart rate?
yes it does
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
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
Do daphnia have organelles?
Yes, daphnia do have backbones.
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.
