Answer:
The correct answer is "Runaway sexual selection".
Explanation:
Runaway sexual selection, also known as Fisherian runaway in honor to Ronald Fisher the scientist that proposed it, is a type of sexual selection on birds, at which exaggerated male ornamentation are developed since females prefer males with these characteristics. Runaway sexual selection is a biological paradox, since male with exaggerated ornamentation are selected by the females but also are more easily caught by predators. Runaway sexual selection fits the description of the species of bird herein described.
A zoologist analyzes the jawbones of an extinct mammal and concludes that it was an herbivore. The zoologist most likely came to this conclusion based on the shape of the teeth.
Animals that consume plants, such as deer, elephants, cows, and many others, are known as herbivores. They eat a range of vegetables, fruits, grasses, grains, and other foods depending on the habitat of the specific animal, hence they are essentially vegetarians.
The broad, flat teeth of herbivores are perfect for chopping up the plant material they consume. These animals' teeth enable them to break down the fibers in their food, making it much simpler for them to digest.
Plant-eating animals known as herbivores have large, flat molars and sharp incisors. They don't own any dogs. The incisors, canines, and molars of omnivores are used for a range of foods. The teeth of herbivores are designed to crush and ground vegetation.

Answer:
IgE
Explanation:
Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.
They are known to be produced by produced by plasma cells (white blood cells).
Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.
In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
