[#631] Rubber tapping method having 100% intensity is
Correct Answer

(D) S 2 d 2

Explanation

Solution: The rubber tapping method having 100% intensity is S 2 d 2 . Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Rubber tapping is not damaging to the forest, as it does not require the tree to be cut down for the latex to be extracted.

Solution: The sweetening of potato tubers caused due to Long term tuber storage at 0° - 50°C. Sweetening is the accumulation of reducing sugars in potato tubers at low storage temperatures. Thus, it is also known as Cold-induced Sweetening (CIS). The relationship between genetic resistance to CIS and two starch parameters, amylose content and starch granule size. It is undesirable because it results in dark fry products.
