The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.
Answer:
<em>The correct option is D) The energy of the car will decrease, and the energy of the block will increase. </em>
Explanation:
As we know energy cannot be created or destroyed but it can change from one form to another. When the wooden car will collide with the wooden block, some of the kinetic energy with which the car was moving will be passed to the wooden block. As a result, the wooden block will also get pushed along the track. Meanwhile, as the wooden car had transferred some of its energy, its energy level will decrease and it will move slower than before pushing the wooden block along with it.
Answer:
By avoiding direct competition among these species, for example, by feeding at different times, by occupying distinct habitats, by niche differentiation, character displacement, etc.
Explanation:
Resource Partitioning is the strategy that similar species, living in the same area, can develop to avoid the competition among them, thereby ensuring their survival and preventing their decrease in population size. This strategy consists of avoiding direct competition by using limited resources in different ways (as above exemplified), thereby maximizing the efficiency in the use of these available resources.
