The diagram below shows four fossils found in different time periods. Fossil A is the oldest and fossil D is the youngest.

Fossil A is from a four-toed animal and shares many similarities with fossil B. Likewise, fossil B shares many similarities with fossil C, and fossil C shares many similarities with fossil D, which came from a hoofed species. Additionally, fossil A and fossil D have never appeared in the same geologic time period.

Which of the following assumptions about the history of these fossils is best supported by this evidence?
A.
A new four-toed species evolved from a hoofed ancestor.
B.
A hoofed species died out and was replaced by an unrelated four-toed species.
C.
A new hoofed species evolved from a four-toed ancestor.
D.
A hoofed species interbred with a four-toed species to create a hybrid species.

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 is the similarities and differences between bacteria and eukaryote?
