True
Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments.
Prior to the experiments being performed, proper planning is done. After the experiment is carried out, the data is noted. Once the data is noted, results are inferred.
If the evidence agrees with the prediction then the hypothesis is being supported and validated. If the result fails to validate the hypothesis then the hypothesis need to be abandoned or modified.
<u>Answer</u>: d. it will release chemical messengers.
The action potential, which is an electric pulse, will travel down the axon untill it reaches the synapses. At the synapses, neurotransmitters (chemical messengers) will be released by the neuron.
Your spinal cord works like a Telephone wire, sending messages back and forth between your body and your brain.
Answer:
The carbohydrate is one of the most important nutrients needed in the diet of an athlete, as they are important to increase their performance during physical activity and exercise.
Carbohydrate is the main source of energy needed by the brain and by our body for its proper functioning. when carbohydrates are eaten up they are broken up into small sugar unit called as glucose.
These glucose unit are stored in the muscle and liver in the form of glycogen to be used as a fuel at the time of exercise and during intense physical activity. It is known to enhance the athlete performance by delaying the fatigue and help them to compete for a longer period of time.
