Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
D. lactobacillus is the right answer
Answer:
<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>
Explanation:
Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.
Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription. RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
