It is true that the collecting tubules merge to form the ducts of Bellini.
Papillary ducts or collecting ducts or the renal collecting tubules were formerly known as the ducts of Bellini. They are structures which are present in the distal portion of the collecting ducts in our kidneys.
These ducts are formed when collecting tubules merge. They receive the renal filtrate, which is the precursor to urine, from a number of medullary collecting ducts and it empties into a minor calyx. These ducts regulate the reabsorption of water and also balances the electrolytes.
Hence option a is the correct option.

<>"A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials. Google: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse."<>
Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).
