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 Moon completes a circle around the Earth in approximately 28 days.
Answer:
After constructing a prototype of the device, the student concludes that in many regions the monetary cost of building and installing the device would be higher than the cost of acquiring water from other sources. Which of the following would be most appropriate for the student to do next?
redesign the device without the solar panel so that it plugs into an electrical outlet
Explanation:
Because of cost implication, the device is redesigned in order to use other source rather than water which would be cost-effective and generally accepted for use.
Humans have an interdependent relationship with other organisms just like organisms in an ecosystem are interdependent.
<h3>How are organisms interdependent?</h3>
To be interdependent means that the involved parties are mutually dependent i.e. they are reliant on one another.
Living organisms in their natural habitat are dependent on one another for food, space, mate and other resources.
However, humans are also interdependent on other organisms for resources like food, raw materials. For example, we eat plant and flesh derived from other organisms.

Answer:
Respiration links up the simple sugar, <u><em>glucose</em></u><em>,</em> with the gas <u><em>oxygen .</em></u>
Explanation:
In the process of respiration, oxygen is used to breakdown glucose. Water and carbon dioxide are produced due as a result of this reaction. A huge amount of energy, in the form of ATP is also released during this process. ATP is used by almost every cell of the body to carry out normal cellular functions. Energy is mainly stored in the linkage between the second and third phosphate of an ATP molecule.
