Which of the following lymphoid organs is NOT matched with its function? bone marrow:_________ a) form lymphocytes Peyer's patches: b) site of B cell maturation thymus: c) site of T cell maturation spleen: d) remove old red blood cells

Answers

Answer 1

Answer:

Answer:

Peyer's patches: b) site of B cell maturation

Explanation:

B lymphocytes are produced in the bone marrow and get mature in the bone marrow only so the site of B cell maturation is bone marrow, not Peyer's patches. B cells produce antibodies that help in destroying microbes.

Peyer's patches are lymphatic tissue mass which is found especially in the mucosa and submucosa of the ileum. This lymphoid organ has a large number of B lymphocytes which monitors the intestinal bacteria and prevents the growth of pathogenic bacteria in the intestine.

Electromagnetic technology is used in many different ways today. Which of these are uses of this technology?

Answers

Electromagnetic spectrum is used in electromagnetic technology in making of high-speed trains ,metal detectors,etc.

What is electromagnetic spectrum?

The electromagnetic spectrum consists of radiation which consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The waves are arranged in decreasing order of energy and decreasing order of wavelength.Gamma rays have the highest energy while radio waves have the lowest energy.

What is the likely motivation for a person giving up soup after an extended illness? Values Habit Social interactions Positive associations Negative associations

Answers

Answer:

The correct answer is: Positive Associations.

Explanation:

Due to prolonged illness the person has lost all desire to survive.
This is the reason why he stopped consuming food.
Under such a situation, it is necessary that the person should be exposed to people who can positively counsel the person and make the ill person realise the importance of life.
It is necessary to make the person realise what he would gain if he chooses to survive and what he would lose if he chooses to die.
It is necessary to remind the person of all the possible goals he could achieve in his life if he chooses to survive.

Final answer:

A person may give up soup after an illness because they might develop a negative association with it. This is due to a psychological phenomenon called conditioned taste aversion, where the person associates the food with the unpleasant feelings of being sick.

Explanation:

The most likely motivation for a person to give up soup after an extended illness may be due to negative associations. After a long period of illness, a person may associate the consumption of soup with the period of sickness and, thus, develop aversion to it. This aversion could lead to the decision to stop consuming soup. This psychological phenomenon is also known as 'conditioned taste aversion'.

For example, imagine a person consumed a particular soup while sick for an extended time. Even after recovery, each time this individual thinks about or tries to eat that soup, it might trigger memories of being unwell. These negative emotions can be so strong that the person might steer clear of that soup in the future, despite soup being originally a comfort food or a staple in their diet.Remember, this is associated with our survival instinct—an evolutionary mechanism to prevent us from consuming harmful food substances that might have caused illness in the past.
