kogti [31]

Answer:

<u>1. type IV hypersensitivity: delayed-type hypersensitivity.  </u>

<u>2. type I hypersensitivity: IgE  </u>

<u>3. type II hypersensitivity: IgG  </u>

<u>4. type III hypersensitivity: immune complexes </u>

Explanation:

Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.

Which best explains the evolution of gymnosperm plants?

Gymnosperms, or sometimes termed as seed plants, are classified as vascular plants and has been thriving for centuries on earth through producing seeds. They are multicotyledonous and are the opposite of flowering plants. Conifers would be the most abundant group of gymnosperms while the cycads come in second. Gingko would place last with just having one species under its name.
