Many antibiotics work by preventing bacteria from building a strong cell wall that can protect them. For example, the antibiotic penicillin keeps bacteria from making the most common molecule that is needed to build their complete cell walls. This causes the cell wall to burst and the bacteria to die. Would antibiotics also work to destroy viruses? A. Yes, because all viruses have cell walls. B. Maybe, because only some viruses have cell walls.
C. No, because viruses have a cell membrane but no cell wall.
D. no because viruses do not have cells at all

When analyzing tree rings, what do scientists assume a thin ring indicates?

Iguanas need to live in a habitat that is very warm, so the pet store warms their enclosures with "basking lights" which act as an artificial sun. describe how the three methods of thermal energy transfer may take place within the iguana's enclosure.

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.
