Answer:
Tube 1- blue-black colour
Tube 2- blue colour
Explanation:
Lugol's solution was first prepared by a French Physician, Jean Guillaume August Lugol. It was formerly used as a tuberculosis therapy and it consists of iodine and potassium iodide. It is still used as medication for iodine deficiency and also as an antiseptic.
Benedict's solution is used to test for reducing sugars.
Starch is known to react with iodine to form a blue-black starch-iodide complex. Hence, when a solution of Lugol's reagent is added to the starch, a blue-black colouration is observed due to the formation of the starch iodide complex.
Starch does not react with Benedict's solution because the reducing moieties in starch are not free. When starch reacts with Benedict's solution, even at 37°C, the solution remains blue because the starch ahas not been hydrolysed in order to enable reaction with Benedict's solution.
Answer:
carbonhydrate

took the quiz and got it right
Answer:
The second diagram explains the steps of the formation of the sun. In a wide expanse of space, gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material, with the planets close behind. In the center, the material clumped together to form a protostar that would eventually become the sun.

Answer:
Seminiferous,Rete testis, Efferent ducts
Explanation:
Seminiferous tubules are coiled tubes that make up most of each testis. The cells and tissues in the tubules are responsible for spermatogenesis, which is the process of creating sperm.
After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis. The rete testis helps to mix sperm cells around in the fluid secreted by Sertoli cells. The body reabsorbs this fluid as sperm cells travel from the seminiferous tubules to the epididymis.
The efferent ducts are a series of tubes that join the rete testis to the epididymis. The epididymis stores sperm cells until they’re mature and ready for ejaculation.
