Varies in your presuppositions/worldview. In the case of Young Earth Creationism, run away subduction (Catastrophic Plate Techtonics) explains the tectonic activity during and after the flood. This model was created by John Baumgardner. In the old earth uniformitarianismistic view it is the latest in the 300 million year cycle of collisions of techtonic plates. Each cycle has the continental plates crashing into each other. This can not be effectively modeled due to the unobservable past.
H-zone in a contracted sarcomere differ from that of a relaxed sarcomere . Yes its true because H-zone is narrower in contracted sarcomere. The functional unit of striated muscle is sarcomere. Sarcomere is the very basic unit of skelatal muscle. Between two Z line sarcomere is the repeated unit .Hence we can say that H-zone in a contracted sarcomere differ from that of a relaxed sarcomere.
Answer: operon
Explanation:
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
The three domain system divides organisms into groups based on similarities in their ribosomal RNA. The three domains in the three domain system are the archaea, eukarya and the bacteria. The domains Archaea and bacteria are all prokaryotic microorganisms, or single-celled organisms whose cells have no nucleus. Domain Eukarya on the other hand has organisms whose cells have nucleus.
The first is incomplete dominance (a mix of the two alleles is formed because neither one is dominant), the second is multiple alleles, and the third is codominance (both traits are equally expressed. Hope that helps :)
