do members of the same phylum share more characteristics than members of the same class?​ Explain why or why not.
SVEN [57.7K]

Answer: No, they don't.

Explanation:

In the taxonomic rank (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species-- in that order) because phylum comes before class, it means it covers a broader spectrum of organisms. So, the traits are less specific. As you narrow it down, the members of the rank will share more and more traits in common.

Here is an example:

Humans are a member of the phylum chordata. All members of phylum chordata share the same 5 traits at some point in their lifetime. (Some only show the traits when they are embryos/larvae). These 5 characteristics share a tail, a notochord, a single, hollow nerve cord, pharyngeal slits, and an endostyle (thyroid).

So, now that we've established that humans are from phylum chordata, we can narrow it down to what class they are in. Humans are in the class mammalia, meaning they are mammals. All mammals not only share those 5 characteristics of phylum chordata, but they also share characteristics that unite them with each other. They all have hair, mammary glands in females, and are endothermic.

So, while members of the phylum chordata share at least 5 traits, members of the class mammalia share at least 8.

I hope that makes sense!

Inessa05 [86]

Answer:

1. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE.

2. IgM

Explanation:

The antibodies are proteins that are Y-shaped and are also called immunoglobulins. The antibody is produced when any pathogen attacks the body. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE. The antibody contains two heavy and two light chains. The IgM is a pentamer immunoglobulin. The IgG is contains two gamma heavy chains and two light chains. The IgA is mostly monomeric. The IgD have two delta heavy chains and light chains. The IgE contains two ∈ chains and light chains.

IgM is produced first. The IgA produced after IgM on mucosal surfaces. The IgG is present in serum. The all immunoglobulins IgM, IgA, IgD, IgE, and IgG are abundant in blood circulation.
