Answer:

Acquired immunity

Explanation:  

Acquired immunity is a type of immunity that we obtain by exposing ourselves to new antigens. When our body is exposed to a new antigen, the T cells, and the B cells, which are lymphocytes, attack the antigen by creating specific antibodies and activating other cells that prevent the antigen from harming the body. Some of these B and T cells transform into memory cells that will circulate through our body for years. As a result, when our body is exposed again to the same antigen, the memory cells recognize it and start a quick immune response by synthesizing specific antibodies.

Vaccines use this method. They have a modified or artificial pathogen similar to the real one, so when we are injected with it, our body develops antibodies for that specific pathogen. As a result, if we are infected with the pathogen again, our body will have a quick immune response and stop the infection.

melisa1 [442]
<span>Option C ie Learning to choose high quality sources of foods is the answer I would select as the least important role of nutrition and wellness education. This is because the judgement of quality requires several considerations that are subjective. For example a bargain price store or market may well supply high quality basic foodstuffs but that would not be taught easily in the classroom context.</span><span />

The nurse has educated a patient with low back pain about techniques to relieve the back pain and prevent further complications.
Licemer1 [7]

Answer:

d) "I will avoid prolonged sitting or walking.

Explanation:

In order to prevent chronic low back pain and further complications, the nurse will ask to limit the time of walking and sitting. the patient shall not stand for hours with low back pain, nor will the patient sit for hours in one posture. Both the postures i.e. prolonged sitting or continuous walking may exacerbate the pain. some activity like sitting and standing every now and then is essential to keep the low back muscles from stiffening. The patient needs to keep their posture straight i.e. bending the waist while lifting objects, twisting the waist, keeping the legs elevated thus shifting the load on back, are all prohibited and may increase severity of low back pain.
