With the advancement of technology, the development of biotechnology began. Biotechnology is defined as the use of living organisms for a specific purpose. The most familiar uses of biotechnology include pharmaceutical companies that create drugs for rare diseases, the transformation of biomass into fuel to power cars and buildings, and the use of enzymes to clean up oil spills.

Answer:
Yes, different cell types also have special duties, like building skin or bone, pumping out hormones, or making anti-bodies.
Explanation:
Cell is the basis structural and functional unit of a living organism. The body of a human is composed of trillions of cells that are organized in around 200 types of cells.
<u>A tissue is simply a group of specific kind of cell that have a specific role.</u>
- For example: The nervous system contains cells called neurons that have ability to transmit message from one place to another and allow us to respond to any environmental stimuli, such as heat, cold, danger etc.
- Skin cell is composed of cells that have a role in protecting the body against the attack of harmful microbes. They also protect have role in building new skin cells and adding the protection to our body.
- Blood cells have a role in providing us immunity (for example white blood cells) therefore, make us better able to protect ourselves from danger of diseases.
- Muscle cells help us in moving our organs as well as allowing the whole movement from one place to another.
Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.
Hope it help!
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
- Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
- Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
- Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
- Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
- Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
Answer:
Digestion
Explanation:
The breakdown of foods into forms that can be transported to cells and absorb into these cells(this process has two parts): Mechanical(breaks down large pieces of food into smaller ones) and Deglutition(swallowing).
