Ayud Aproximadamente el 70% de los norteamericanos blancos perciben el gusto de la sustancia química feniltiocarbamida, y el resto no es capaz de percibirla. La capacidad para percibir el sabor de esta substancia química está determinada por el alelo "T", mientras que la incapacidad para percibirlo se determina por el alelo recesivo "t". ¿Cuál es la frecuencia de los alelos "p", "pq" y "q" en la población mencionada para que la misma se encuentre en equilibrio, conforme al Principio de Hardy-Weinberg?

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the answer would be d

allowed for the prediction of the properties of missing elements.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
