Answer:
False
Explanation:
For glucose to go in and out of cells, the cells need to have a protein channel in their cell membrane.
Answer:
The correct answer is - auscultation.
Explanation:
Auscultation is one of the four diagnosis procedures that physical examiner uses to diagnose disease or infection of the body. In this procedure sound of the body are heard by the help of the stethoscope that helps to magnify the internal sound generating in lungs, heart, blood vessels and vein, and other part of the body.
Thus, the correct answer is - auscultation.
Responder:
<h2>1.892mol / L
</h2>
Explicación:
La molaridad se define como la relación del mol de una solución por litro de su solución.
Molaridad = Mole de soluto / solución (en litros)
La solución aquí es agua = 250 ml = 0.25L
El soluto es cloruro de potasio (KCl)
Para obtener el mol del soluto, usaremos la fórmula;
Mole del soluto = Masa de KCl / Masa molar de KCl
Masa dada de KCl = 35 g
Para la masa molar de KCl donde K = 39 g / mol y Cl = 35 g / mol
Masa molar de KCl = 39 + 35 = 74 g / mol
Mole del soluto = 35/74 = 0.473 mol
Molaridad = 0.473mol /
0.25L
Molaridad en la solución = 1.892mol / L
