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.
The Xylem transports water and minerals while the Phloem transport organic nutrients
Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
B is the most effective and feasible, and it prevents the initial introdution of the species
I believe the answer is comparative anatomy. It is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies, such that both provide evidence of evolution. Similarities in embryos are evidence of common ancestry. For example all vertebrates embryos have gill slits and tails.
