We know that sea turtle hatchlings use Earth's magnetic field to navigate. Do they also use light cues from the moon to get from the sand to the ocean waves? Outline an experiment to answer this question.

Question

Accepted Answer

Okay everyone, let's take a look at this practice problem. We have blank is a sense that allows an organism to detect the Earth's magnetic field. So our answer should be something that detects a magnetic field. Typically organisms detect changes in their bodies and environments using receptors. If we take a look at the suffix of each of our answers, we see that they all end in reception and that means that they are involved in some sort of detection for an organism. Since our answer should be something about magnetic fields, our prefix of the word should be associated with magnetism in some way. So let's go ahead and take a look at our answer choices. We have a thermal reception. This is a process that organisms use receptors to detect temperature changes. And remember we're looking for something about magnetic fields and so A. Is going to be incorrect. Then we have B. Chemo reception using chemo receptors. And organism uses this process to detect changes in the chemical stimuli. So think chemo means chemicals. So B is also going to be incorrect. See photo reception using photo receptors. An organism uses this process to detect light and so C. Is also going to be incorrect. Lastly we have magneto reception. The magneto prefix means magnetic and therefore this is the sense of an organism to detect Earth's magnetic field. And so d is going to be our final answer. I hope this was helpful and I'll see you guys for the next practice problem
