Answer: A and B
Explanation:
Monosynaptic reflex arc consists of only two neurons, one motor neuron and one sensory neuron. Monosynaptic means the presence of a single synapse of chemicals. Monosynaptic reflex Arc simple reflection that involves transferring input from the sensory neuron to the correct motor neuron through a single synapse in the spinal cord.
For example: the action of knee-je.rk reflex.
As the A refers to sensory neuron and B refers to motor neuron, sysnapse between A and B is a part of Monosynaptic reflex arc .
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.

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.
