Answer:
The stratum corneum cells are flattened (filled with keratin) and the stratum basale cells are cuboidal-shaped to columnar, this is achieved through the keratinization process.
Explanation:
The epidermis is the outermost layer of the skin, it protects us against toxins, bacteria and fluid loss. It's composed of 5 sub-layers of cells called keratinocytes. These cells produced in the innermost sub-layer (stratum basale), migrate to the outermost sub-layer (stratum corneum) maturing and undergoing a series of changes. This process, known as keratinization (or cornification), makes each of the sub-layers different.
The stratum basale consists of a single layer of cuboidal cells that are arranged above the dermo-epidermal junction. In the stratum basale are the stem cells (adult stem cells) of the keratinocytes, which rise to the keratinocytes of the interfollicular epidermis (lacks hair follicles). Trunk cells have a cuboidal shape to columnar shape.
The stratum corneum is the most superficial layer formed by degenerated keratinocytes called corneocytes. In the last stage, the corneocytes lose the nucleus, are filled with keratin, and are surrounded by a cornified cell layer formed by a shell of interlaced proteins, in addition to a lipid wrapped covalently bonded. The cell death of granular stratum cells causes the progressive loss of desmosomes along the stratum corneum, which leads to peeling or shedding of cell debris. Filaggrin is added to keratin in very tight beams, which causes the cell to collapse into a flattened form.
It is important because it allows scientists to classify, group, identify, and properly name organisms through the method of taxonomy. This method was brought about by Linnaeus Carolus.
I really hope this helps! I love science :D
Answer:
Aquaculture is a type of farming performed in water bodies like lakes, ponds, oceans to breed aquatic plants and animals like fish, mollusks, crustaceans, algae, etc. Aquafarming is done to increase food production and to earn money from it.
Apart from the advantages aqua farming has several disadvantages. One of the main disadvantages is the transfer of parasites or diseases from one fish to another is easy in aquaculture because fishes live in dense populations in aquaculture. So fish in aquaculture are highly vulnerable to diseases.
Excess fecal matter produced by farmed fish can pollute the ecosystem which has an adverse effect on the other species live in that ecosystem.
Answer:
It would be=
14 protons -
17 electrons=
-3 :D
When you subtract protons from electrons, you get the electrical charge.
