If 322 particles of air are in a container , how many are Nitrogen? Oxygen? Argon?
arsen [322]

251.16‬ nitrogen gas particles

67.62‬ oxygen gas particles

0.13 argon gas particles

Explanation:

Air is a mixture of many gases. Different gases have their own percentage composition in air.

Nitrogen = 78%

Oxygen = 21%

Argon = 0.04%

Since the air in the container is made up of 322 particles, we can find the the number of nitrogen, oxygen and argon gases in it;

Number of Nitrogen gas = \frac{78}{100} x 322

                                         = 251.16‬ nitrogen gas particles

Number of oxygen gas = \frac{21}{100} x 322

                                       = 67.62‬ oxygen gas particles

Number of argon gas = \frac{0.04}{100} x 322

                                     = 0.13 argon gas particles

En un experimento un floricultor cruzó plantas de flores púrpuras con plantas de flores blancas, los resultados obtenidos durant
aliina [53]

Answer:

Los genotipos de los parentales son:

- pp (homicigota dominate con flores púrpura)

- bb (homocigota recesivo con flores blancas)  

Explanation:

Alelos:

p: púrpura y b: blanco

Genotipos parentales:  

- pp: homocigota dominante (flores púrpura)

- bb: homocigota recesivo (flores blanca)

Cruzamiento parental: pp X bb

F1: 100% pb  

Cruzamiento F1: pb X pb

F2: 25% pp (flores púrpuras), 50% pb (flores púrpuras) y 25% bb (flores blancas)

En este caso, el alelo que determina el color púrpura es dominante sobre el alelo que determina el color blanco. Es por esta razón que en la F1 todas las plantas heterocigotas exhiben un fenotipo con flores púrpura. En la F2 la proporción fenotípica será 1:2:1 (1 homocigota dominante, 2 heterocigotas y 1 homocigota recesivo), mientras que la proporción genotípica será 3:1 (3 plantas con flores púrpuras y 1 planta con flores blanca).
