¿Qué sucede con un pasajero que está de pie en un autobús cuando este inicia el
movimiento?
¿Por qué sucede eso?

Answer:

El pasajero se mueve hacia atrás.

Explicación:

Cuando el autobús comienza a moverse hacia adelante, el pasajero que está parado en un autobús se mueve hacia atrás debido a la inercia. La inercia es una propiedad en la que un cuerpo resiste cualquier cambio en su estado de reposo o movimiento. Al principio, el pasajero está en reposo, por lo que cuando el autobús comienza a moverse en la dirección de avance, el pasajero se mueve en la dirección de retroceso para permanecer en reposo debido a la propiedad de la inercia. Por eso el pasajero se mueve hacia atrás.

Indicate whether the statements below are TRUE or FALSE.

1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.

2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.

3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus adds 5 units of risk for the disorder and that a recessive allele at any locus adds 3 units of risk for the disorder. Individuals with 26 or more units of risk develop the disorder. The environment does not affect the presence or absence of this disorder. How many risk units will be present in an individual of genotype AABbcc
