I would say A. Quantitative data involves numbers and stuff like that. Unlike qualitative data, which involves pictures and not numerical data. I hope this helped.
By definition, an arthropod is an animal that is invertebrate and has an exoskeleton also known as an external skeleton. In addition they have a jointed appendages. Other characteristics include segmented bodies, open circulatory systems and bilateral symmetry. Based on this we can say that from the list given we can select "endoskeleton" "jointed appendages"
The three types of symbiotic relationships are commensalism, mutualism, and parasitism.
Commensalism: One organism benefits from the symbiotic relationship while the other remains unaffected. Example: Barnacles and whales.
Mutualism: Both organisms benefit in the symbiotic relationship. Example: Humans and the bacteria in their digestive tract.
Parasitism: One organism in the symbiotic relationship benefits at the other organism's expense. Example: Fleas and dogs.
C. Hypothermia
Answers A, B, and D are all good strategies to ensure that you do not overheat during practices. Hypothermia is a condition that occurs when your body becomes unhealthily cold. It is not something that you can/should do to yourself, and would only hurt you if you were to attempt it as a strategy to stop overheating.
