Keratinocytes are differentiated skin cells found in the outermost layer of the epidermis. Dendritic cells are antigen-presenting cells that play important roles in the adaptive immune response.
- In addition to keratinocytes, the <em>stratum spinosum</em> also contains another epidermal cell type called epidermal DENDRITIC cells that help to fight infection.
- The s<em>tratum spinosum</em><em> </em>is an epidermal skin layer between the <em>stratum granulosum </em>and<em> stratum basale</em>.
- Dendritic cells are antigen-presenting cells that are capable of processing harmful antigens in order to present them on the cell surface to the T cells of the immune system.

Answer: The results will tell us about the correctness of hypothesis.
<u>Explanation:</u>
The Hypothesis is that explanation which is used as a starting of any investigation. The Hypothesis can or cannot be correct. We can test the hypothesis with scientific research.
Now a student can make conclusions about the hypothesis based on the results obtained. If results are the same as the hypothesis it means that our proposed explanation i.e hypothesis was correct but if the result differs than it means the hypothesis was not correct.

Answer:
It must belong to the Kingdom Fungi.
Explanation:
Fungi are the organisms that have long thread-like structures called hypha in their body. Many hyphae together form a mass called mycelium. Fungi are eukaryotes and have a well-defined nucleus in their cells. They also have cell walls that are made up of chitin. Fungi are mostly multicellular. However, yeast is the fungi that have a single cell in their body. Fungi are heterotrophs and derive their nutrition by parasitic or saprophytic mode of nutrition. Therefore, the given description tells that the microbe should be a fungus.
