Cephalization is the development of nervous tissues becoming concentrated towards the anterior end of an animal. Triploblasty means that an organism has three tissue layers, an ectoderm (outer layer), mesoderm (middle layer), and an endoderm…

All of the hair was examined under a microscope under high magnification. We drew sketches of all the hair and identified the cuticle, cortex, and medulla. We identified all of the unique characteristics…

is when the keratinocytes and keratin are dead and shed off in the top layer of the epidermis. The skin completely renews entirely every 28 days. Keratin also plays a role in the hair. The hair has three levels the cuticle, the cortex and the medulla, the keratinocytes are in the cuticle which is the outermost layer. Keratin is also found in the Medulla in pigmented cells. Another place that keratin is very important in the nails, if we didn’t have keratin in the nails we wouldn’t have nails at…

Brown-Barnacle is the ability of crowded organisms on the shore to become columnar. This conserves space, which is a highly contested resource. Another structural adaptation of the Brown-Barnacle is their waterproof cuticle that provides an effective barrier to water and salt. This cuticle also provides protection against evaporation and water loss that occurs due to osmosis. Another structural adaptation of the Brown-Barnacle is their calcareous exoskeleton which is strong, and cements them to…

Think of me. Don’t go.” A rowdy woman was screaming at me on my right. She was the devil perched upon my shoulder while Werner was…
