Introduction:
The main type of cells which make up the epidermis are Markel cells, keratinocytes, with melanocytes and Langerhans cells. The subdivision of layers of the skin is strata carneum, strata lucidum, stratum granulosum, and stratum spinosum and stratum basale.
Answer to Problem 1TYR
Correct answer: Option (d) stratum carneum.
Explanation of Solution
Rationale: This is the topmost layer, consists of dead cells that shed periodically and is progressively replaced by cells formed from the basal layer.
Option (a). Papillary layer. It is the upper most layer of the dermis. It intertwines with the rete ridges of the epidermis and is composed of fine and loosely arranged collagen fibres.
Option (b). Stratum spinosum. It is a layer of the epidermis found between the stratum granulosum and stratum basale.
Option(c).Stratum basale. It also contains melanocytes, cells that produce melanin, the pigment primarily responsible for giving skin its colour.
Option (e). Stratum granulosum. It is a thin layer of cells in the epidermis.
Stratum carneum is the top layer of the skin and it protects the living cells beneath it by providing a tough barrier between the environment and the lower layers of the skin.

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references.
