Las unidades de medida de temperatura son los grados Celsius (ºC), los grados Fahrenheit (ºF) y los grados Kelvin (K).
• Para convertir de ºC a ºF use la fórmula: ºF = ºC x 1.8 + 32.
• Para convertir de ºF a ºC use la fórmula: ºC = (ºF-32) ÷ 1.8.
• Para convertir de K a ºC use la fórmula: ºC = °K – 273.15.
• Para convertir de ºC a °K use la fórmula: °K = ºC + 273.15. Realice los siguientes ejercicios utilizando las formas de conversión
a. 50 °K a ºC
b. 70 ºC a °K
c. 485 ºC a ºF
d. 2380 ºF a ºC
e. 70 ºF a °K
f. 265 °K a ºF
g. 234 ºC a °K
h. 143 ºF a ºC
i. 432 °K a ºC

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
