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:
120 gramos de CO₂
Explanation:
La ecuación química balanceada para la combustión del hidrocarburo propano (C₃H₈) es la siguiente:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Para convertir las moles a gramos usamos el peso molecular (PM) de cada compuesto:
PM(C₃H₈)= (3 x 12 g/mol C) + (8 x 1 g/mol H) = 44 g/mol
masa de C₃H₈ = 1 mol x 44 g/mol = 44 g
PM(CO₂) = (1 x 12 g/mol C) + (2 x 16 g/mol O) = 44 g/mol
masa de CO₂ = 3 mol x 44 g/mol = 132 g
Ahora podemos ver que se producen 132 gramos de CO₂ (3 moles) a partir de 44 gramos de C₃H₈ (1 mol) ⇒ 132 CO₂/ 44 g C₃H₈
Multiplicamos la relación estequiométrica por la cantidad de propano que tenemos para calcular la cantidad de CO₂ producida:
40 g C₃H₈ x 132 CO₂/ 44 g C₃H₈ = 120 g CO₂
Entonces, se producen 120 gramos de dióxido de carbono al quemar 40 gramos de hidrocarburo C₃H₈.
Answer:
yes they both have midtochondeias
The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
