Answer:
The correct answer is: True.
Explanation:
- Obesity is a disease condition in which the BMI or Basal Metabolic Index of a person goes beyond normal.
- The BMI of a person is calculated by finding the ratio between the weight of the person measured in kilograms and the square of the height of the person measured in metres.
- A person having a BMI below 18 is considered to be underweight, between 18 and 25 is normal weight, between 25 and 30 in overweight and above 30 is obese.
- The disease is caused more due to social reasons than biological reasons.
- When a person A lives near the vicinity of another person B who is obese, this means the person A lives in an environment where a proper balanced diet is not maintained during the consumption of food. They tend to consume food rich in oil and fat.
- Hence, the intake of the fat rich food by the person A will result him in consuming fat and oil in amounts far more than his body actually requires. Excess fats deposits in the body thereby increasing his BMI and resulting into obesity.
- Due to obesity the person B will also show the symptom of being lethargic and will not prefer to do exercises. This lethargy would be induced in person A as well.
When Timmy steps on the rose bush, the sensory receptor on his toe receives the stimuli, sends it the spinal cord through a sensory neuron which they initiates a response sent through a motor neuron to the muscle and he withdraws his leg in pain.
<h3>What is a reflex arc?</h3>

- withdrawing the foot quickly when one steps on a sharp object
- withdrawing the hand quickly when one touches a hot surface
- the je_rking of the knee
- coughing or sneezing, when irritants enter the nostrils.
Reflex actions do not need to involve the brain, hence they occur very quickly.
The path of a reflex arc begins with a sensory receptor which receives the stimuli, travels to the spinal cord through a sensory neuron which they initiates a response that is sent through a motor neuron to an effector such effector such as a skeletal muscle.
In conclusion, a reflex arc is the path of a reflex action through the body.
