Answer:
the I bands to appear smaller
Explanation:
I band is the lighter and a less dense area of the sarcomere. It contains no thick filaments. A Z disc passes through the center of each I band. During muscle contraction myosin heads become attach to and slide along the thin filaments at both ends of a sarcomere. It pulls the thin filaments toward the M line and makes the thin filaments slide inward and meet at the center of a sarcomere. This inward movement of thin filament allows their ends to overlap.
As the thin filaments slide inward, I band and H zone narrower. I band and H zone become disappear altogether when the muscle is maximally contracted. The width of the A band and the lengths of the thick and thin filaments remain unchanged.
Answer:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.

i hope this helps bc i think its D. not entirely sure.
The study of 2 organisms is called binomial nomenclature
Without frequent ground fires to clear out dead brush, a woodland becomes more susceptible to catastrophic wildfires and forest fires that can completely destroy the forest.
However, large forest fires are a natural phenomenon that occur less frequently than small ones.
What happens to smells and aroma's as they move through the air on their own is that they start to fade away when they get a a certain point. Sometimes they just stay is one spot and don't move.
I hope this helps!
