Answer:
Small, knot like protusion on the skin are called<u> Skin Cysts</u>
Explanation:
Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. When you have some, they feel like large peas under your skin. Cyts are usually caused by an infection, clogging of sebaceous glands, or around foreign bodies, such as earrings. They may contain pus, fluid, or other material.
Answer: The congenital insensitivity affects reflex arc receptors.
Explanation:
Congenital insensitivity to pain is a congenital disease caused by mutations of various genes that affect nociceptors throughout the body, which transmit information about pain. It mainly correlates with the SCN9A gene, which encodes information to form the sodium channel NaV1. .7., Whose function in neurons is to transmit electrical signals.
The reflex arc is a neutrophysiological mechanism to respond to a stimulus, they can be simple or compound, simple if it only consists of a neuron that encompasses the entire process or compound, as in most, thus, the latter consists of:
1. Receivers
2. Sensory or afferent neurons
3. Motor or emerging neurons
4. Effector organs.
There are 4 types of reflexes, the innate, conditioned, myotactic reflex and the spinal automatism reflex.
With this information we can deduce that the congenital insensitivity to pain involves the nociceptors, which are the receptors of the myotactic reflex, compound reflex, damaged by the disease, avoiding the withdrawal of the part of the body affected when a painful stimulus occurs, causing multiple characteristic lesions of this pathology.
Increased salivation is not a side effect of chemotherapy.
Cancer is a disease caused by the uncontrolled differentiation of the normal cells. To kill the fast growth of the normal cells use of multiple drugs treatment called Chemotherapy is done. This treatment is a primary treatment done to treat cancer patients. Chemotherapy treatment shrinks the cancerous cells so that they can be easily removed by radiation or surgery. This treatment apart from curing the disease also shows side effects like -
- Sudden weight loss is known as Anorexia.
- Hair loss is known as Alopecia.
- Swelling of the mouth is known as Stomatitis.

Answer:
False.
Explanation:
Power may be defined as the rate of doing work with time. The S.I. unit of power is J/s or watt. The power is a scalar quantity as it has only magnitude and no direction.
The power can be calculated by the formula:
Power = work done/ time taken.
From the formula, it is clear that power is inversely proportional to the time taken by the body. Hence, if the work remains constant, power will decrease with time.
Thus, the answer is false.
