Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducin
Phoenix [80]

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.

The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.

Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

The resulting pain and inflammation when pleural fluid is unable to prevent friction between opposing pleural surfaces is known
Effectus [21]

Answer

The correct option is B.

Reason

            A brief technical explanation for each option is given below.

a. Asthma

                 It is lower respiratory disorder in which air passage way become narrow and swells, produce extra mucus which make difficulty in breathing, and trigger sneezing, wheezing and shortness of breath.

b. Pleurisy

                 It is lung disease in while pleura, lining of lung and chest cavity become inflamed due to accumulation of pleural fluid. The fluid is accumulated through the process of pleural effusion which may be transudate or exudate.

c. Pulmonary hypertension

                           It is a condition in which blood pressure increase in lung arteries. It leads to shortness of breath, swelling of legs and fast heartbeat.

d. COPD

               Stand for chronic obstructive pulmonary disorder. It is a progressive lung disorder accompanied with chronic bronchitis, emphysema and non-reversible asthma.  

e. Emphysema

at over 5 million degrees celsius the temperature of the sun core is high enough for nuclear to occur
Paraphin [41]

Answer:

Yes (but not how you think)

Explanation:

I'm assuming that you mean if nuclear fusion, where two atoms (in this case mostly hydrogen) fuse into one heavier atom, and release a lot of energy.

However, fusion happens when there is a tremendous amount of pressure or heat. This is found in the core

The 5 million degrees is found on the surface of the sun, but at the core, it is at 15 million degrees.

In addition, the pressure is so extreme that if forces atoms to become one, despite the fact they don't like being together (try finding 2 strong magnets and hold them so that they try to repel each other and try and make them touch, it's hard! Now imagine having to put a million of times the amount of strength!)

So, the sun is capable of nuclear fusion, but at the core, where it is 15 million degrees!

(fun fact: scientists are trying to build "mini-suns" called Fusion reactors to try and harvest the power of the sun!)

What is the nuclear charge of this ion?
saw5 [17]

nuclear charge is always positive, because there are only protons in the nucleus, and protons are always positive.

But this is in general, because you have not mentioned the ion name.
