Scientists have successfully cloned sheep and cattle for several years. A farmer is

considering the advantages and disadvantages of having a flock of sheep cloned

from a single individual. Din the issues the farmer should take into account

before making a decision. Your response should include:

• how a cloned flock would be different from a noncloned flock

• one advantage of having a cloned flock

• one disadvantage of having a cloned flock

• one reason that the former could not mate these cloned sheep with each

other to increase the size of his flock

one reason that the offspring resulting from breeding these sheep with an

unrelated sheep would not all be the same

Which of the following is an advantage of solar energy?

Sperm pass through the and connect to a short ejaculatory duct. vas deferens prostrates seminiferous tubules none of the above

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.
