3. Surface tension of a water strider For an animal the size of a human, surface tension seems to be a rather small and insignificant force (though it plays an important if unnoticed role in our breathing). But as animals get smaller, surface tension gets increasingly significant. (The weight of the animal goes down with the cube of the size while the surface tension only decreases linearly.) For animals like the basilisk lizard and the jacana (bird), they appear to...

20 points) Water striders walk on water by taking advantage of surface tension; they live on the surfaces of ponds, vers, and even the open ocean. A team of scientists at MIT decided to build a robotic water strider to mimic the true strider's locomotion and lean more about not just how it floats, but how it moves around the surface of the water (see picture below) Both the actual water strider and its robotic counterpart are held up by...

Station 4: Ape and Human Anatomy- Effects of Bipedalism 5. Compare the gorilla and human skeletons on the next page. While humans are bipedal, gorillas generally use all four limbs in locomotion (although they can walk for short distances on two legs). What differences do you see in the skeleton of these two primates that reflects these differences in locomotor behavior? Trait Gorilla Human a. Opposable thumb on feet? (Yes/No) b. Position of skull on th c. Relative length of...

A flamingo is able to stand on one leg without using any muscles. It can do this by locking its leg joints so that it acts as a rigid body. (a) If the height of the centre of mass is 110 cm above the ground, and the width of the flamingo's foot is 10 cm. What angle would the Flamingo be able to tilt without falling over? We can use a mass of 3.5 kg for the bird 110cm 10cm...
