The cell cycle is the replication and reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called Binary Fission, allows for them to live on by dividing into two new daughter cells
Answer:
<h2>Function as Waterproofing and works as a barrier to infection. </h2>
Explanation:
1. Keratinocytes are maintained at various stages of differentiation in the epidermis.
2. Keratinocytes are responsible for forming tight junctions with the nerves of the skin.
3. The outer layer of skin, the epidermis containing keratinocytes, which provides waterproofing and serves as a barrier to infection.
4. It is barrier to foreign particles and provide physical strength.
5. It helps in innate immune system.
I’m pretty sure it is a Jellyfish. Please let me know if it is correct.
Both the terms "living" and "biotic" describe an organism that holds life. However, an organisms stops "living" after it dies, but never stops being "biotic". This is because "biotic" means anything that has ever had life, whereas "living" only describes things currently alive.
Answer: Paracrine
Explanation:
Paracrine signaling is a form of cell signaling in which a cell produces a signal that induces changes in nearby cells, altering the behavior or differentiation of those cells. Molecules known as paracrine factors diffuse over relatively short distances (local action), unlike endocrine factors (hormones that travel considerable distances over the circulatory system), juxtacrine interactions, and autocrine signaling.
<u>Cells that produce paracrine factors secrete them into their immediate extracellular environment. </u>These factors then travel to nearby cells where the gradient of the factor received determines the outcome. However, the exact distance a paracrine factor can travel is not known with certainty.

In the case of infection, cells of the innate immune system secrete different cytokines into their immediate extracellular environment that attract other immune system cells such as neutrophils and lymphocytes, to fight the infection.
