Question 3 (1 point)
which of the following is a correct statement about photosynthetic responses to climate change?
question 3 options:
under higher co2 concentrations, photosynthetic rate is generally expected to decrease
c4 plants are expected to profit more from higher levels of co2 than c4 plants
photosynthetic rate is mostly immune to temperature changes until a certain temperature maximum
under high temperatures, co2 solubility is decreased which reduces the photosynthetic rate

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.

Which of the following is not associated with invasive species?

The ultimate purpose of respiration: a. inhale 02 and exhale co2 b. place oxygen in the lungs c. place oxygen in the blood d. deliver oxygen to every blood cell
