Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.

<h2>Anatomy of Aorta</h2>
Explanation:
- The protein elastin is found in connective tissues all through the body. It is eminently found in the extracellular lattice of the skin just as the inward organs of the body. The name elastin sounds a lot of like 'flexible.' This is no fortuitous event. The elastin protein is adaptable and gives numerous tissues their versatility.
- Inferable from its exceptional capacity to extend and withdraw, the aorta additionally fills in as a store that changes the profoundly compelled and pulsatile heart yield into a progression of moderate variances.
- The tunica intima comprises of a solitary layer of ECs that lines the lumen of the vein and is moored to the fundamental cellar film, an exceptionally particular ECM organize comprising basically of laminin, collagen type IV, fibronectin, perlecan, and heparan sulfate proteoglycans.
- This storm cellar layer additionally assumes a vital job in flagging occasions that direct EC movement, intrusion, expansion, and survival. The cellar film together with the inward flexible lamina (IEL) fills in as an interface between the tunica intima and tunica media.
Answer: The base pair rule for RNA is that adenine pairs with uracil, thymine pairs with adenine and cytosine pairs with guanine.
Explanation: RNA contains adenine, uracil, cytosine and guanine while DNA contains adenine, thymine, cytosine and guanine. Thymine is not found in RNA while uracil is not found in DNA. In RNA base pairing, Watson and Crick proposed a rule that wherever adenine is found in DNA, Uracil occurs in the complementary RNA strand, wherever thymine is found in the DNA strand, adenine is found in the complementary RNA strand and wherever guanine occurs in the DNA strand, cytosine is found in the complementary RNA strand.
