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.
True because that will make you have a healthy water balance lol
Answer:
Activates or suppresses
Explanation:
The hormonal system or the endocrine system involves chemical systems where feedback loops of hormones are released directly into the circulatory system by internal glands.
It involves the interaction between the hypothalamus, pituitary glands and sex glands.
Release of hormones is dependent of signalling therefore behaviors such as stress, eating patterns and tension can activate or suppress various aspects of the hormonal system.
Answer:
The word photosynthesis contains clues to its meaning: the prefix photo comes from a Greek word meaning “light.” The root synthesis comes from another Greek word meaning “to put together.” Through photosynthesis, plants use the energy of light to put a meal together using water and carbon dioxide.
Explanation:
Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.
glycerol is a 3-carbon molecule with 3 -OH groups.
fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.
when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.
this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.
hope this helps!
