Answer:
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
Answer:
velocidad de reacción
Explanation:
Las enzimas son proteínas que catalizan reacciones, es decir, aumentan la velocidad de reacción. Si se quiere evaluar el efecto de cambiar el pH en una reacción enzimática, se debe realizar la reacción a distintos valores de pH e ir midiendo la velocidad de reacción. Por lo tanto:
pH: variable independiente
velocidad de reacción: variable dependiente
La velocidad de reacción podría medirse a través de la cantidad de producto que se forma por unidad de tiempo, o a través de la cantidad de sustrato que se consume por tiempo.
Trophic Levels describe the transfer and different stages of the organisms transferring energy. I just called it Trophic level energy flow in school.
The structure of DNA is called a double helix because DNA is made up of two strands of nucleotides wound together in a spiral.
DNA has two strands that run opposite of each other and twist together much like a twisted ladder. Each backbone of the ladder is made up of alternating groups of sugar and phosphate groups.
