Answer:
The conclusion is false, because it is assuming that correlation = causation.
Explanation:
An important principle in statistical analysis is the principle that when correlation exist between two variables or more, it does not mean that one of the variables are causing the other to appear in a certain manner.
Remember that correlation means that you are investigating whether a relationships exists between two variables; in this example, as we can see, it is between the biodiversity in an ecosystem and the population of an insect.
The graph can be said to illustrate the result of the research; that as the biodiversity of the ecosystem goes down, the insect's population goes up. This is a form of negative correlation.
However - we do not know what is the direction of the relationship; the student concludes that as some insects die within the ecosystem, the researched insect's population goes up; assuming that the predator species died off and thus the researched insect's population increases.
Yet, it is also possible for the relationship to go towards the other direction; the researched insect population increases - perhaps by the introduction of a new food source that causes the species' population to increase - and thus, this damages the biodiversity of the ecosystem, making the population go down since it is possible that the researched insect is instead the species which is on top of the food chain at that ecosystem.
To investigate the direction of a relationship, further research need to be done and more sophisticated statistical methods need to be used.
Answer: option 'a' Is the correct option. ''officials should act according to the views of the electorate''.
Explanation:
See, before we start checking which option is right or not. Let us first know what the delegate theory of representation means;
The delegate theory of representation means that the electorates will vote in their candidates as delegates which acts according to whatever the electorates says they(delegates) should do.
Now let us look at the option 'e' which says that; 'opinion is only a barometer, to be used as the legislator sees fit'. This does not go with what is defined above that explains what the delegate theory of representation means.
This is the same with options 'd' ,' c' and 'b'. Only option 'a' goes with it. So, option 'a' is right.

Troponin binds to Ca2+ from the sarcoplasmic reticulum. The propagation of an action potential along a skeletal muscle fiber causes the release of Ca2+.
What is a cross-bridge cycle?
As seen by the cross-bridge cycling, the action of the contractile proteins shortens muscles. The cross-bridge muscular contraction cycle can be seen in many types of muscles, including cardiac, smooth, and skeletal muscles. Therefore, when riding across bridges, all muscle groups contract.
What transpires in skeletal muscle during a cross bridge cycle?
The Pi dissociates after the myosin creates a cross-bridge with actin, causing the myosin to proceed through the power stroke and shorten the sarcomere, which lowers its energy state. In order to dismantle the cross-bridge
