Answer:
A.it pumps hydrogen ions inside the cell
Explanation:
Principally, the main role of electron transport chain is to maintain the electrochemical gradient of hydrogen ions (H+) inside the mitochondrial matrix. This is the last step in aerobic cellular respiration and performs a series of redox reactions. Overall, it allows accumulation of H+ inside the mitchondrial matrix. This increased gradient or accumulation of hydrogen ions (H+) is essential because H+ would accept the electrons producing during the reactions. Without this, the flow of electron will be stopped because of high gradient, and production of ATP will not happen as well.
Indeed ETC helps in production of ATP but that is not the main function of electron transport chain rather it is a function of mitochondria.
Answer:
They became closer to each other.
Explanation:
When skeletal muscles contracts the Z lines that are at the end of every sarcomere became closer to each other due to the fact that the I bands that are attached to the Z lines and contains the myosin filaments move closer to each other interacting with the actin filaments and shorten the the H zone that is in the middle of the sarcomere. In other words, It all becomes compact during a contraction.

Two examples include Cyanobacteria streptococci. Prokaryotes don’t really create systems into higher orders of living things so they create chains like the two I mentioned
