This is stratified keratinized squamous epithelium.
<h3>What are the characteristics of stratified keratinized squamous epithelium?</h3>
- A kind of stratified squamous epithelium known as keratinized stratified squamous epithelium has cells that have multiple layers of thick keratin in the apical portion of the cells.
- Skin and underlying tissues can benefit from the stiff, fibrous intracellular protein keratin's ability to protect them from heat, bacteria, and chemicals.
- In the process of keratinization, the cells build up keratin as they ascend, transforming into thin, metabolically inert pockets of keratin devoid of nuclei.
- As cells distance themselves from the nutritive blood supply and the organelles eventually perish, the relative amount of keratin in the cells rises.
- The cells on the top layer lose all function as a result of keratinization and are now primarily involved in protecting against mechanical stress and dehydration.

According to this question, a student is trying to decide which kind of bottle to purchase, however, he is considering the kind that will have lesser negative impact on the environment and society.

In accordance to the student's heart for the sustainability of the environment, he should choose the METAL BOTTLE because the metal bottle is RECYCLABLE i.e. can be reused. Recycling of most materials has been encouraged in order to curb the spread of non-biodegradable materials like plastic that can serve as pollutants to the environment.
