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.

If a woman is homozygous for red hair and her husband is homozygous for brown hair, what is the probability that they will have
boyakko [2]
Well, you failed to mention which one is the recessive trait in this instance. But, let’s say red hair is recessive, denoted by r and brown hair is dominant denoted by R. Mom is rr and dad is RR. All children are going to be Rr and so heterozygous. They will all carry the trait for red hair but will express brown hair themselves, so 0% probability of having a child with red hair from the initial parents
