Ascientist shines low levels of ultraviolet radiation on a dish containing colonies of ruby-red bacteria. he then makes several replicate plates from this dish over many generations. he finds that in addition to the ruby-red color, there are also pink, orange, and light red bacteria. which of the following is the best explanation for these findings?

Imagine that a mouse has white fur because of a mutation in its dna. which of the following conclusions can be drawn

What is thought to have caused the mass extinction at the end of the cretaceous period?

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.
