- Desert owls are inactive during the day and active at night. They also have small bodies. This describes a ________ adaptation to the hot and dry desert. CHECK ALL THAT WOULD APPLY A)physiological B)anatomical C)behavioral D)No answerA fish poisoned with 100 units of mercury was caught and eaten. That mercury was obtained from eating 10 smaller fish that had 10 units of mercury. Those smaller fish each ate 10 even smaller fish that each had one unit of mercury. Describe what is happening.Experiment on The Predator-prey Interactions Between Zebrafish and Daphnia1. Six 1-L beakers were filled with aged tap water.2. To test the effect of light on the survival of Daphnia, the 6 beakers were divided equally into 2 treatments: light & dark. Beakers assigned to the dark treatment were covered w/ aluminum foil.3. One zebrafish (about 2-3 cm) starved for 24 hours was placed in each beaker.4. Fifty (50) Daphnia sp. individuals were added in each beaker containing the starved zebrafish. The top of the beakers assigned to the dark treatment were covered with aluminum foil.5. One hour after, the zebra fish was scooped out & the no. of surviving Daphnia in each set-up were counted. QUESTIONS:1. What would be your hypothesis in this experiment? 2. What is your basis for formulating that hypothesis? 3. What do you think will happen to the survival rate of Daphnia when…
- a experiment of Brown Anole Lizard Distribution is conducted to perform my experiment I will choose 4 spots in a park such as a lake, a shaded tree, a boardwalk, and a sidewalk. then to quantify my results I will go three times a day for five weeks and count how many lizards I see in each area. what would the control would beAn American cockroach (Periplaneta americana) can quickly begin to turn away from approaching danger, such as a hungry toad lunging toward it or a flyswatter wielded by a person, after the air pushed in front of the moving object reaches the roach’s body. A cockroach has very sensitive wind sensors (mechanoreceptors) on its cerci, which are small appendages at the end of its abdomen. One cercus points slightly to the right, the other to the left. Use what you know about moth orientation to bat cries to suggest how this simple system might provide the information the roach needs to turn away from an attacking toad, rather than toward it. Also, briefly describe how might you test your hypothesis experimentally?How do whales and dolphins get oxygen at night?A. They absorb oxygen from the water.B. They sleep in just one hemisphere at a time.C. They lower their metabolism so that they need to breathe only a few times per night.D. They store oxygen in their digestive system.
- Lilliputian is a term that comes from Book 1 of Gulliver's Travels. It means ..... inferior large in size diminutive in size superiorA biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. He has collected data and comes up with the linear model T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation. The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute. The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.When water birds have had their feathers fouled with crude oil and they are cleaned by rescuers, why are they not immediately released?
- Crickets “chirp” by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets “call” to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.
