The correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto
Explanation
The Kuiper Belt is the most remote area of the solar system, it is an elliptical region, which is more or less 149.5 million kilometers from the sun. Its name refers to the fact that it is a belt, so it could be associated with the appearance of the asteroid belt that is located between Mars and Jupiter. However, in the Kuiper Belt most objects are icy rather than rocky. In this region of the solar system you can find several dwarf planets such as Pluto, these planets are classified as such because their size is enough to be considered as or asteroids, but they cannot be considered planets either because they do not meet any requirement. According to the above, the correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto

Answer:
Allergens differ from antigens because *they do no stimulate the immune system resulting in the production of leukocytes rather than the stmulate the IgE antibodies*
Explanation:
Allergen and antigen are both foreign substances that can cause certain disorders to animals, but there is some difference between them in terms of their nature and the diseases caused by them. An allergen is a nonparasitic foreign substance that can cause certain immune reactions in the body when it enters the body. Whereas, an antigen is a foreign substance that can trigger the immune system to produce a specific immune response. This immune response leads to produce antibodies that can neutralize or destroy the foreign substances that entered the body.
Allergens can produce Systemic Allergic Response. Allergens stimulate the IgE antibodies by binding to them on the mast cells and causing the mast cells to rupture and release histamine, serotonin, and heparin, initiating inflammatory response.
Answer: Growing is capable to a certain living organism. Growth means getting larger in size, and for multi-cellular organisms this is done by making more cells. Plants have special tissues called meristems where growth occurs. Single celled organisms increase their numbers by dividing and making more cells like themselves.
