Answer:

Explanation:

The responding variable always is measured against the variable that you have control over.

In this case, you have control over the volume of air.

The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.

Which best explains how heat plays a role in the movement of materials within Earth's interior?

vfiekz [6]

Answer:

Hot material near the core is less dense and rises, when it cools, it becomes more dense and sinks.

Explanation:

This best explains how heat plays a role in the movement of materials within Earth's interior because it's how convection works. Convection is the circular motion that happens when warmer air or liquid which has faster moving molecules, making it less dense rises, while the cooler air or liquid drops down. Convection currents within the earth move layers of magma, and convection in the ocean creates currents.

Escriba las fórmulas semi desarrollada y global correspondientes a: 2,3-dimetil-1-penteno

hammer [34]

Answer:

En la imagen adjunta.

Explanation:

Hola.

En este caso, debemos recordar que la fórmula semi desarrollada se relaciona con la fórmula estructural del compuesto orgánico a representar; de este modo, primeramente encontramos una cadena de cinco carbonos con un doble enlace en el primer carbono y dos radicales metil tanto en el segundo como en el tercer carbono. Por otro lado, la formula global muestra el tipo y número de átomos presentes en el compuesto, que para el dado, son siete átomos de carbono y catorce de oxígeno, según se puede observar en la imagen adjunta.

¡Saludos!
