Maggie is a member of her school’s environmental club and is interested in recycling. She asks the question, “How does exposure to the environment affect recyclable plastics?”

What best describes why and how Maggie should change her question to make it a better scientific question

A. The answer to the question leads to a testable hypothesis, so the question should be changed to prevent testing.
B. The question involves giving an opinion about recycling, so it should be changed to rely only on facts.
C. The focus of the question is too broad, so it should be narrowed to a single environmental factor.
D. The results are too uncertain, so the question should be changed to one that has a known outcome.

Aresearcher is studying the science of attractiveness and asks volunteer test subjects to rank what trait they find most attractive in a person what type of variable is the dependent variable in this experiment

For each of the following, decide whether the statement describes photosynthesis, cellular respiration, or both. releases energy in the form of atp. stores energy in glucose molecules. performed by producers. performed by consumers.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
