In multicellular organisms, cells and organ systems are specialized to perform specific tasks. For example, the respiratory system in animals and the shoot system in plants allow these organisms to take in the atmospheric gases they need and release the waste gases.

What is the most probable hypothesis that can be made if one organ system is damaged in a multicellular organism?
A.
If one organ system is damaged, the whole organism will not be affected in any way.
B.
If one organ system is damaged, the organism will adapt and perform the damaged system's functions.
C.
If one organ system is damaged, the whole organism will not function properly.
D.
If one organ system is damaged, the other organ systems will experience a higher rate of mutation.

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

What do you think car designers do if the damage caused by a crash test is too severe?

1. how much energy is needed to raise the temperature of 40.0 g of argon from 25c to 40c? the specific heat capacity of argon is 0.520 j/(g·k) 2a. 23.0 ml of 0.100 m hcl (standard) are added from a buret to neutralize 50.0 ml of an unknown basic solution. 2b. if the oh- produced in the previous reaction came from ca(oh)2, then what is the molarity of the ca(oh)2? 3.calculate the new freezing-point of a solution when 60.5 grams of cacl2 solute is dissolved in 0.612 kg of water. 4. what is the maximum number of moles of alcl3 that can be produced from 5.0 mol al and 6.0 mol cl2? 5. a sample of oxygen gas has a volume of 150 ml when its pressure is 0.923 atm. if the pressure is increased to 0.987 atm and the temperature remains constant, what will the new volume be? 6. nitrogen gas in a closed container at a temperature of 100.0 oc and 3.0 atm is heated to 300 oc. what is the pressure of the gas at the higher temperature?
