Imagine that we have two rabbits which we call subject 1 (s1) and subject 2 (s2). at s1 we feed it with grass, and at s2 we give it meat for a previously established time. after this process it is pertinent to ask the students: what will happen to s1 and s2? in what way could the changes produced by the feeding form of s1 and s2 be identified externally?

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
