Amphibians are dying in large numbers after being infected by an aquatic fungus called Batrachochytrium dendrobatidis. The origin of this fungus is unknown, but scientists suspect that humans are helping spread it. More than 350 amphibian species have been affected, and at least 200 species of frogs have suffered serious reductions in population or become extinct. The map below shows the worldwide distribution of dendrobatidis. www. maps. net What will be the most likely impact of the decline in frog populations resulting from the fungal infection? A. New species of frogs that feed on both the fungus and the infected species of frogs will evolve.

B. Plants will no longer grow in the waters of the affected ecosystems, and fish species will increase.

C. The fungus will move on land and destroy reptile and mammal populations in tropical ecosystems.

D. Populations of algae and mosquitoes will increase, leading to fish die-offs and potential increases in human malaria cases.​

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.
