Treehoppers have a major predator, the jumping spider. Researchers hypothesized that the ants would protect the treehoppers from the spiders. In an experiment, researchers followed study plots with ants removed from the system and compared them to a control plot. Which of the following is consistent with the results shown in the graph? 100, Plants with ants 80- 60 408 Plants without ants 20어 20 25 30 10 August 15 July O Ants reduce the numbers of treehoppers. O Ants do somehow protect the treehoppers from spiders. Spiders eat treehoppers when ants are present. O Treehoppers do not produce honeydew in July and are not protected by the ants. Ants eat the honeydew produced by treehoppers. Average number of young treehoppers per plant

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
