Answer:Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other. The organism that feeds is called the predator and the organism that is fed upon is the prey. There are literally hundreds of examples of predator-prey relations.

Licemer1 [7]

Cory is reluctant to leave her home and attend college despite just being finished with her teenage years. Usually, the people of this age are explorative and are trying to find their identity in the world separately, but Cory seems to stay isolated even from Mike, which indicates that she might be going through the stage of stress. Stress makes a person to avoid any kind of interaction with other people and inhibits the urge to explore the life outside one's comfort zone. So, Cory is going through the stress stage.

If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years
adelina 88 [10]

Answer:

15 atoms

Explanation:

About 15 atoms out of the 120 Adams would remain.

<em>Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.</em>

Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.

Out of 120 Adams,

  • <em>the first half-life will reduce 120 to 60 Adams</em>
  • <em>the second half-life will reduce 60 Adams to 30 Adams</em>
  • <em>the third half-life will reduce 30 Adams to 15 Adams.</em>

<em>Hence, at the end of the 17,190 years, approximately </em><em>15 Adams</em><em> would remain.</em>

Answer:

la tecnología del Sistema de Posicionamiento Global (GPS)

Explanation:

Los guepardos son animales capaces de acelerar rápidamente, llegando a alcanzar una velocidad de 29 metros por segundo (aproximadamente 110 km/h). Los biólogos de vida silvestre determinaron la velocidad de los guepardos mediante la utilización de collares con GPS. Para la colocación de estos collares, los guepardos tuvieron que ser parcialmente sedados mediante la utilización de dardos tranquilizantes. La tecnología del GPS permitió la localización y de este modo la determinación de la extraordinaria aceleración que alcanzan los guepardos; sin embargo, esto es sólo un aspecto de su estrategia para cazar, ya que a partir de esta tecnología fue también observado que estos animales son capaces de girar y detenerse repentinamente al atrapar una presa.
