You are to respond to the following conversation in Spanish. You are having a conversation with a friend from school about an upcoming test in your math class. Friend: Hola, amigo! Cómo estás? You (1): Friend: Estás listo por el examen de matemáticas el viernes? Me siento muy preocupado porque no hey estudiado bastante! You (2): Friend: Si fuera el examen de español, sería fácil, pero no entiendo matemáticas. You (3): Friend: Quieres estudiar conmigo hoy en la biblioteca después de las clases? You (4): Friend: Ah, entiendo! Está bien! Quizás podemos estudiar mañana durante la hora del almuerzo. You (5): Friend: Bueno, hasta luego! Ciao!

(1) Hola! Estoy bien y tú? (2) No, no estoy lista todavía. No he tenido la oportunidad de estudiar esta semana. Estoy muy preocupada también. (3) Sí, estoy de acuerdo. A mi me gusta más el inglés que matemáticas. Es demasiado difícil. (4) Ay! No puedo! Tengo que practicar con mi equipo de vóleibol. Tenemos un torneo muy importante este fin de semana. (5) Perfecto! Mañana nos vemos en la biblioteca a las 12:00?

A population of dingoes in an Outback region of Australia includes 120 individuals at the start of 2011. At the start of 2012, researchers had observed 18 births and 2 deaths. In addition, they observed 2 individuals immigrating and 3 individuals emigrating. What is the population's net growth rate?

To solve this problem, we must first figure out how much the population has changed from 2011 to 2012. We will divide the change by the initial population to get a percentage growth rate. Population change = (births + immigrants) - (deaths + emigrants). In this case (18 + 2) - (2 + 3) = 15. To determine the growth rate, we must divide the change in population (+15) by the initial population of 2011 (120). 15 / 120 = 0.125. To convert this answer into a percentage, we simply multiply by 100. 100 x 0.125 = 12.5. The population's net growth rate is 12.5%.

While out hiking with friends you see a rattlesnake. Your friends tell you to stay away from the "poisonous" snake. Describe to your friends the difference between poison and venom, state whether the rattlesnake is a poisonous or a venomous animal.

The rattlesnake is a venomous animal because it has venom in specialized sacs that are injected into its prey by biting it with fangs. The difference between poison and venom is that poison must be ingested (you eat, bite, or lick it), whereas venom must be injected (it bites or stings you). Some examples of poisonous animals are Poison Dart Frogs, Cane Toads, and Monarch Butterflies. Some examples of venomous animals are bees, King Cobras, and Black-Widow spiders.
