A lot of things, ranging from volcanic explosions to construction machines to cow farts. The biggest threat would be factories that are producing more than their share of emissions.

Explanation:

It's mainly because of the participants they're made of, and a big thing for the ozone is methane.

For the factories, it's because of the chemicals they put out. That's why they have emission limits.

Len [333]

Answer: To clean the exterior and keypad of the microwave.

Explanation:

It is proper to clean the exterior of the microwave including the keyboard. Although this isn't required to be done daily, Benjy saw his mum do it at the time she decided to clean it (maybe it was stained too) and being a child he picks up the act too.

It is advisable to clean not only the interior of your microwave but the exterior top including the keypad. Cleaning the keypad prevents dirt and dust from staying in them and causing the keypads to get stuck.

I hope this helps

En los alérgicos, a partir del segundo contacto con el alérgeno cuando se produce la reacción alérgica. ¿Cómo podrías explicarlo
dem82 [27]

Answer:

La segunda exposición desencadena la fase de 'respuesta' asociada a la reacción alérgica  

Explanation:

La alergia se puede considerar como una respuesta desmedida del sistema inmune cuando un individuo entra en contacto con ciertas sustancias que son inocuas para la mayoría de la población, pero que en personas alérgicas desencadenan fuertes reacciones de hipersensibilidad. La alergia tiene dos fases conocidas como fase de sensibilización y fase de respuesta. La primera fase de sensibilización es donde el individuo entra en contacto con los 'antígenos' del alérgeno, lo cual provoca que el individuo genere anticuerpos IgE los cuales combaten al alérgeno (el sistema inmune considera que esta sustancia es potencialmente dañina), mediante la generación de anticuerpos de IgE que se unen a receptores de células del sistema inmune (eosinófilos, basófilos y mastocitos). La segunda fase de respuesta se produce cuando el individuo entra de nuevo en contacto con el alérgeno. Durante el segundo contacto, los antígenos del alérgeno interactúan con anticuerpos específicos de IgE que se encuentran sobre la superficie de células del sistema inmune, desencadenando la degranulación de estas células (mastocitos) y la consecuente liberación de mediadores químicos de la alergia tales como, por ejemplo, histamina, los cuales son responsable de los síntomas típicos de la alergia (tos, estornudos, picor, enrojecimiento de ojos, urticaria, inflamación, etc.).
