Answer: all of the above except ectothermy and thin leaves. Photosynthesis, broad tap root, endotherm and production of antifreeze proteins are adaptation of the organism found in rainforest biomes.
Explanation:
Rainforest presents challenges to the organisms living in it. In order to live in the rainforest, the organisms has to develop several adaptation features.
Such features include;
Photosynthesis: all plants photosynthesize by making use of carbon dioxide in order to produce oxygen and sugar.
Broad tap root: since the soil is moist, plants need a broad tap root for proper anchorage.

Answer : B) In step 2, there was a chemical change which was observed in sugar.
Explanation : In A step 2 there was a physical change that was seen. By just boiling the dissolved salt solution salt was obtained. Therefore, it is a physical change. In B step 2 there was a chemical change seen as sugar solution was thickened and turned brown. It was not obtained in its original form; there was a chemical reaction that took place during sugar evaporation. As chemical change is the one where the reaction is irreversible.
Therefore only in B step 2 there was a chemical change that was observed.
