Answer: Option A. "Cytoskeleton"

Explanation:

Cytoskeleton can be defined as the network of protein filaments in the cytoplasm eukaryotic cells interlinking from cell nucleus to cell membrane.

There are three basic types of protein fibers present in cytoskeleton that includes micro filaments (Actin filaments ), microtubules and intermediate filaments.

Microfilaments are consist many linked monomers of a protein known as actin, that combines in a double helix with a diameter of about 7 nano-meter and functions as serving tracks for myosin (motor protein).

Microtubules are arranged in a form of hollow straw like structure made up of consist of tubulin proteins having diameter of about 25 nano-meter and further consist of two subunits, α-tubulin and β-tubulin.

Intermediate filaments are the cytoskeletal element which are made up of multiple strands of fibrous proteins wounded together having an average diameter of 8 to 10 nano-meter.

The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.

What is Basal cell carcinoma?

The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).

  • It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.
  • When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
  • Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.

The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.

The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.

Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.

never [62]

Comparisons of the aging theory scientist made by the scientist :

In the early age the scientist assumed that aging is the process in which the wear and tear of cells occurs and this results in the process of aging. When our body functions for longer period the cells tends to wear out due to the continuous usage for a longer period.

The rate of living theory assumes that how faster an organism consumes oxygen the quicker the cells wore out and result in aging process. There are also several other theories which discuss in brief about the aging process.
