Read the paragraph from the introduction [paragraphs 1-3]. There are trillions of cells in the human body, and they come in different shapes and sizes. There are also hundreds of different types of body cells. Each one has a specific job it is built to do. Groups of cells of the same type make specific tissues.

What conclusion can the reader make based on this paragraph?

A
There are more cells in a human body than in a plant.
B
All cells are tissue cells.
C
Humans could not live without cells.
D
Some cells are more important than other cells.

Which of the following is not a defining characteristic of plants?

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