Force=5,000N
Distance= 0.25m
Work done by the Jack=
force×distance
= 5,000×0.25
=1250joules
Therefore, the Workdone by the Jack is 1250Joules

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.
