Hunt and her team designed an experiment to test her hypothesis about the effect of BPA on mice. They administered daily doses o
katovenus [111]

Answer and Explanation: The figure below shows the doses of BPA administered to the female mice over time.

An experiment is used to determine cause and effect among variables. When the research is for the impact of a treatment, researchers randomly separate individuals in two groups:

  • <em><u>Control</u></em> <em><u>Group</u></em> doesn't receive any treament or a placebo or a treatment whose outcome is already known;
  • <em><u>Treatment</u></em> <em><u>Group</u></em> receives the treatment;

For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the <u>others</u> are <u>treatment group</u>.

The variables in a experiment are classified as independents or dependents:

  • <em><u>Independent</u></em> <em><u>Variable</u></em> is the cause;
  • <em><u>Dependent</u></em> <em><u>Variable</u></em> is the effect;

For the BPA research, since it is the effect of BPA over time on the mice's cells it is being investigated, <u>dosage</u> of BPA is the <u>independent</u> variable and <em>time</em> is the <em>dependent</em> variable.

alex41 [277]

Answer:

r-selected species (e.g., American bullfrog)

Explanation:

The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
