In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. the birds will guard their catches from other birds, and move the caches if they start to dry out. these caches provide a food source for the birds during the winter. what is an abiotic factor that contributed to the evaluation of this set of behaviors? a. limited food availability b. being preyed upon by larger birds c. competition with other birds for space d. cold winter climate

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.

What noticeable trend from this graph might be used to make a conclusion?

What condition is kept close to its set point in osmoregulation? a. body temperature b. platelet count c. blood glucose level d. water balance
