Video transcript

Hello everyone and welcome to today's video. So today we have a type of fish that is using local water movement in order to detect predators. And we are asked what type of receptors these organs that detect these water movements are. So whenever we have have a question like this where we are given a certain animal and were asked what type of receptor it is portraying. We first need to identify what signal it is getting. Well the fish is using this water movement a signal. So the main signal is motion or the motion of these waves. The motion of the water. So let's keep that in mind as we go over answer choices. Let's begin by answer choice A camel receptors. These camel receptors as these prefects implies are specialized in detecting chemicals so they detect certain chemicals in the environment here remember that we're looking for something that takes motion. So this is definitely not going to be. Then we have c thermal receptors. Again look, always look at the prefects thermal text changes in temperature. Again we're looking for changes emotions. So this is not going to be the answer choice either. Electoral receptors. The text changes in an electric field which is not mentioned in these questions. So we're going to also cancel that out. And this all leaves us with mechanized receptors but I want you to recall from previous videos what these mechanism receptors usually detect and they detect changes in touch pressure, stretching sound waves and motion which is what the question is asking for. So because of that answer. Choice B making A receptor is going to be the final answer to our question. I really hope this video helped you, and I hope to see you on the next one.

Considering that sounds and odors both trigger changes in the patterns of action potentials in sensory neurons, how does the brain perceive which sense is which when the action potentials reach the brain? a. The action potentials stimulated by sounds are different in size and shape from those stimulated by odors. b. The axons from different sensory neurons go to different areas of the brain. c. Mechanoreception is not consciously perceived by the brain, whereas chemoreception is. d. Chemoreception is not consciously perceived by the brain, whereas mechanoreception is.

Scientists generally think that a 'good hypothesis' is one that is reasonable and testable and inspires further research into a phenomenon. Using these criteria, explain whether Dalton's hypothesis about color vision was a good hypothesis. Was it correct?

Scientists collected data on the date of onset of the menstrual cycles in a group of women who moved into a college dormitory together in the fall. The y-axis of the graph shows the mean difference (in days) between the onset of a woman's cycle and the average onset date of the rest of the women. Evaluate whether these data provide evidence for the existence of a human pheromone.
