Medicine
1 answer:
Aleksandr [31]4 years ago
5 0

Answer:

Most correct answer is all of the germ layers

Explanation:

Mucous membranes constitute the innermost layer of a number of hollow organs (i.e.: gastrointestinal tract). They are composed of an epithelial lining which overlies a deeper layer of connective tissue. Typically, each of these components arises from a different germ layer. For instance: the mucous lining of the gut arises from a combination of endoderm-derived epithelium and lateral mesoderm-derived connective tissue. Other mucous membranes may have different origins, for example: The mucous lining of the oral cavity is composed of ectoderm-derived epithelium and underlying connective tissue derived from head mesenchyme (combination of cephalic neural crest and paraxial mesoderm).

Summary:

Mucous Membrane = Epithelium (derived mainly from endoderm, followed by ectoderm, rarely mesoderm) + Underlying Connective Tissue (usually mesoderm)

ANEK [815]

Most health experts recommend eating tuna a few times a week and eating shark few times a month because: eating these fish could result in the buildup of pollutants in fat tissue of humans.

<h3>Why health experts recommend tuna and shark to be consumed less?</h3>

Large fish like sharks and tuna feed on smaller fish and can accumulate high levels of environmental pollutants like mercury and the risk also increases as off-shore pollution increases.

Shark meat is recommended only a few times a month because sharks are apex predators who accumulate high levels of toxic chemicals and heavy metals from both skin absorption and from consuming prey. This is called bioaccumulation.
