To hypothesize: Why dolphin flippers do not freeze and also to describe an experiment to test the proposed hypothesis. In addition to this, also determine the result that would be expected if the hypothesis is correct. Concept introduction: Dolphins can maintain a constant internal body temperature. Therefore, they are endotherms. They have various mechanisms to maintain a constant body temperature, such as the presence of blubber, a thick layer of fat in their skin and counter current heat exchange mechanism.

Suppose a researcher is investigating the measurement ability of a new device intended to read the freezing point of a chemical compound. The substance used in the investigation has a known freezing point of -24 degrees Celsius. The researcher conducted a series of 10 sample measurements of the freezing point, and the results are represented below. What can we say about the device with regards to its precision, and potential bias? Measurement Freezing Point (degrees Celsius) 1 -26 2 -18 3 -32 4 -31 5 -24 6 -24 7 -24 8 -24 9 -11 10 -37

Consider the following scenario: A group of five treasure hunters have been hired to retrieve some artefacts believed to be in an abandoned castle in an environment similar to the Arctic tundra (this is a quasi-fantasy land where disparate climates can co-exist in ways they can’t in reality, but everyone is human and has human physiology). Their expedition is happening in winter, and the group set out each carrying a pack of supplies including tents, sleeping gear, and food for either 3 well-fed days or up to 8 days with rationing (approximately 30kg each). The treasure hunters travel on foot to get to the castle through lands where there are predators such as wolves and bears. They have two options in terms of speed of travel: slow (7 days to castle), and fast (4 days to castle). 1) As an advisor to the group, which speed would you say they should travel? Note – neither speed is wrong however your answer must justify your choice in terms of physiology. Once the group get to the…

In Science experiments, it is very important to “control the variables” so that there is only ONE independent variable and ONE dependent variable. We “control the variables” by making anything else that could change during the experiment into a constant. For example, if you are doing an experiment to find out what material can hold more water, then it is important to make sure all the materials you are testing are the same size. Why is it so important to control the variables? What would happen if we did not control them?
