Answer:
The Z lines and H- zone shortens during the muscle contraction.
Explanation:
Sarcomere is the area between the two Z lines. The Z- lines are present in the centre of I - band and H - zone is present in the A - band. The actin filaments which are thin filaments present in I- band and contracts, slide over the myosin filament during contraction.
The I - band, H- zones are became shortens as they are thin than the A- band. It is anisotropic band having thick myosin filaments. They are not flexible and remain in its constant shape during the muscle contraction.
After the muscle contraction, the A- band and the H- zone comes to their original shape. In other words, the sarcomere shortens and comes back during muscle contraction, and relaxation.
Answer:
Explanation: Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes. ... The vast majority of protists are unicellular or form colonies consisting of one or a couple of distinct kinds of cells, according to Simpson.
If we had the same climate every minute of every hour tons of carbon would circulate the earth and climate change would make the polar ice caps melt from all the carbon around
Bacterial infections were much harder to treat a long time ago because we didn't have the same technology or information that we do now. because we have worked so long on treating different things we have learned what works and what doesnt. the new technology has helped us understand the infection which led to us being able to find medication to treat said infection.
