Describe the change which will occur if a piece of peeled potato is placed in a concentrated sugar solution and explain why this
skelet666 [1.2K]

Answer:

Through the process of Osmosis, water will move from a region of high water potential ('concentration') to low water potential. Therefore, water will slowly leave the cells of the potato and enter the sugar solution in an attempt to reach equilibrium and the potato will therefore lose mass.

blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω

QUE SON LA BIOMOLECULAS​
DIA [1.3K]

Son consideradas biomoléculas aquellas moléculas que forman parte de los organismos vivos.  

Las moléculas son las unidades físicas de la materia, que se forman a partir de la unión de dos o más átomos agrupados a través de enlaces químicos.

Las biomoléculas se clasifican en inorgánicas u orgánicas.

• Las biomoléculas inorgánicas se encuentran ampliamente en la atmósfera. El agua, algunas sales como el cloruro de sodio, y gases como el oxígeno, son ejemplos de biomoléculas inorgánicas.  

• A las moléculas como azúcares, proteínas, combustibles, entre otras, las cuáles contienen átomos de carbono, hidrógeno, oxígeno y a veces nitrógeno se les llama moléculas orgánicas.

Cuando las moléculas orgánicas forman parte de la materia viva, se les conoce como biomoléculas orgánicas, las cuales incluyen fundamentalmente glúcidos, lípidos, proteínas y ácidos nucleicos.

Por lo tanto, podemos concluir que las moléculas (compuestos que se forman a partir de los elementos químicos) que se encuentran formando los seres vivos se conocen como biomoléculas y se clasifican en inorgánicas u orgánicas.
