I think the correct answer is the microscope that Jack used is a light microscope. This type of microscope uses slides where a sample to be observed is placed. Also, it has a light source in order to have clear observations.

What is the basis on which the subdivisions in a Geological time scale are made
Andru [333]
 <span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them. 
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.

Sorry its so long but that the answer i think >:) ur welcome

Un compañero de tu salón presenta una condición especial llamada gigantismo, ya que su estatura es mucho mayor que la de los dem
MrRissso [65]

Answer:

Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.

Explanation:

En este caso presentado se encuentra una situación diferente a lo que sucede en el gigantismo: hay un problema hormonal en donde la hormona de crecimiento es secretada de manera excesiva. Recibe el nombre de acromegalia cuando sucede después del cierre de la epífisis del hueso, luego de la edad de crecimiento.

Contrast what happens to thermal energy in evaporation and condensation
Alex17521 [72]
Answer - Will try to Answer in simplest form with Reasoning. Since no one responded.

1.Solar-Thermal energy. For example the sun radiates thermal energy aka heat which then turns Liquid aka Water in gas molecules because they are escaping. (Evaporation) 

2. Condensation happens when the water molecule vapor clump together before thermal energy can be separated by it. Such as the clouds which they form tiny vapor/mist. Thats why when your on a plane and when you hit thru that cloud at hundreds of mph. Your hitting water molecules lol.
