expansion amounts for 50 cm of each of the solids:

brass alloy: 0.11 cm
aluminum: 0.07 cm
iron: 0.12 cm
steel alloy: 0.04 cm

each strip of metal was the same thickness and was heated to 100°c.

based just on the data, which conclusion can be drawn?
a) metals expand upon heating.
b) alloys expand less upon heating than elemental metals.
c) alloys expand more upon heating than elemental metals.
d) the rate of expansion of metals is directly proportional to the temperature to which it is heated.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

the answer is c. it will give up it's valence electron to the other atom.
