In your zoology class, you are given a model of a coelacanth to study. as a lobe-finned fish, this coelacanth is distinctly different from a ray-finned fish. noting these differences, what do you expect a coelacanth might be able to do that a ray finned fish could not? check all that apply. check all that apply a. support its body weight with fins b. open its mouth unexpectedly wide c. open its mouth unexpectedly wide d. release oil from its swim bladder e. possess lungs f. be excluded from ancestry of land-dwelling vertebrates

Which of the following is an example of a tissue on the digestive system a.the stomach b.smooth muscle that lines the stomach c.nerve cells in the stomach d. enzyme molecules in the stomach

What is the relation ship between structure and function in an organism

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
