Answer:

when you try to stand or stretch your legs to relieve the discomfort.

Explanation:

n turn, the brain directs a response through the spinal cord, which sends impulses through the motor neurons. In turn, the motor neurons direct the muscles to execute the response. The end result is when you try to stand or stretch your legs to relieve the discomfort.

Which surface of an epithelial cell lies closest to its blood supply
Anettt [7]

Answer: The surface of an epithelial cell which lies closest to its blood supply is called as the Basal surface.

Epithelial cell is primarily composed of two surface-

1) Apical surface- It is exposed to the environment and lies towards the lumen or internal organ cavity.  

2) Basal/ Basolateral surface- It is not exposed to the environment. It lies interiorly and attached to the basement membrane via integrin.

Epithelial cells do not have own blood supply. For obtaining nutrients, they are dependent on the blood capillaries which are present in the nearby tissues. For accomplishing this, the basal surface of epithelial cell plays an essential role. The nutrients from blood enters basal surface via basement membrane which is a selectively permeable membrane.

Thus, basal surface of epithelial cells lies closest to the blood supply.

Which example illustrates adhesion? A.water droplets sticking to a window B.water forming a large drop C.water evaporating from
shusha [124]

Adhesion can be defined as the process of attachment of a substance on the surface another. This attachment can be because of the physical or chemical linkage. The physical adhesion can be reversed using enough force.

Among the given options, the water droplets sticking to a window represents the process of adhesion. The water droplets are attached to the surface of the glass. The water forming a large drop is example of cohesion. The water evaporating from leaf is an example of evaporation, and the water falling from the sky is an example of condensation.

Hence, the correct answer is option (A) - water droplets sticking to a window.

12.36Un balón lleno contiene 12 kg de oxígeno, O2, bajo una presión ma-nométrica de 40 atm. Determine la masa de oxígeno que se
const2013 [10]

Answer:

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Explanation:

Asúmase que el balón es rígido. Supongamos que el oxígeno se comporta como un gas ideal, entonces la ecuación de estado es la siguiente:

P\cdot V = \frac{m\cdot R_{u}\cdot T}{M} (1)

Donde:

P - Presión, medida en atmósferas.

V - Volumen, medido en litros.

m - Masa, medida en kilogramos.

M - Masa molar, medida en kilogramos por kilomol.

T - Temperatura, medida en Kelvin.

R_{u} - Constante de los gases ideales, medida en atmósfera-litros por kilomol-Kelvin.

El aire experimenta un proceso isocórico e isotérmico, entonces obtenemos la siguiente relación:

\frac{P_{1}}{m_{1}} = \frac{P_{2}}{m_{2}} (2)

Nótese que los subíndices 1 y 2 representan los estados inicial y final de proceso.

Si sabemos que P_{1} = 41\,atm, m_{1} = 12\,kg y P_{2} = 25\,atm, entonces la masa final del aire es:

m_{2} = \frac{P_{2}}{P_{1}} \cdot m_{1}

m_{2} = \left(\frac{25\,atm}{41\,atm}\right)\cdot (12\,kg)

m_{2} = 7.317\,kg

La masa que se ha extraído del balón es:

\Delta m = m_{1}-m_{2}

\Delta m = 12\,kg-7.317\,kg

\Delta m = 4.683\,kg

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.
