The correct answer is C. The three germ layers.
The feature which is only shows higher invertebrates as compared to lower invertebrates is referred to s the three germ layers.
Germ layers is termed as the primary layer of cells which forms during embryogenesis. Three germ layers which are invertebrates are pronounced as eumetazoans which includes animals.
An example of an animal which produces two germ layers is Cnidarian which are endoderm and ectoderm and makes them diploblastic.
Chordates produce third layer which is mesoderm and makes triploblastic. Germ layers they give rise to all animals organs and tissues under process known as organogenesis.
Answer:
Melanocytes are located in the stratum basale.
Explanation:
Melanin is the pigment responsible for skin color. It is produced by melanocytes located in the base of the epidermis.
The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
Stratum basale is the innermost germinative, single, basal layer of the epidermis composed of basal cuboidal-shaped cells. These cells are the <em>precursor of keratinocytes</em>, this is why this layer is also called germinativum. In this basal layer, there are also <em>Merkel cells</em> as well as melanocytes.
