A student wants to test if a bean plant will grow taller under green light than under sunlight. Select from the drop-down menu the correct step of the scientific method that each statement describes. Two identical bean plants are grown next to each other. They receive the same amount of water and sunlight. One plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. Measurements of the bean plants’ heights are recorded every day for two weeks.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
