In Experiment 5, how did the shape of the epidermal cells in the outer skin surface slide compare to the shape of the epidermal
Phoenix [80]

Answer:

The correct answer is B. <em>The cells in the outer skin surface appeared flat, whereas the cells in the cross section were not flat.</em>

Explanation:

The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.  

  • <u><em>Stratum basale</em></u> is the <em>innermost germinative, single, basal layer of the epidermis </em>composed of basal cuboidal-shaped cells. These cells are the precursor of keratinocytes, this is why this layer is also called germinativum. In this basal layer, there are also Merkel cells as well as melanocytes.
  • <em><u>Stratum spinosum</u></em> refers to the keratinocytes which produce keratin.
  • <u><em>Stratum granulosum</em></u>, this is the layer where keratinization begins. Cells produce hard granules that change to keratin and lipids as they ascend.
  • <u><em>Stratum lucidum</em></u> is conformed of densely compressed cells, which begins to flatten and appear indistinguishable between each other.
  • <u><em>Stratum corneum</em></u> is the most external layer, composed of dead, flattened cells which are released regularly in a process known as desquamation.

Answer:

A - Hypothalamus and Antidiuretic Hormones

Explanation:

Whenever their is a sudden change in the fluid level in the bodyb, either the blood, sugar, etc., the osmoreceptors, a special group of cells within the hypothalamus part of the brain, will detect this.

Thereafter, a signal is sent to the posterior pituitary gland to release the antidiuretic hormones (ADH), whose job is to maintain the fluid level by causing an increase in water reabsorption into the body through the expansion of the epithelial cells of the kidney.
