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:Expression means the process of making known ones thoughts and feelings. This relates to the concept of gene expression by the fact that the genes characteristics are made known through the phenotypes and the characteristics of the gene and it's information becoming known. The process of making things known in gene sequencing and the creation of proteins and its job.
Explanation:
I hope this helps I haven't taken bio in a couple years lol.
Answer:
Through an anchor
Explanation;
-Protein Ras associates with the membranes through an anchor.
-Ras proteins are molecular switches that decide if and when cells divide inside our bodies, thus an impairment of their function may result in the formation of a tumor or cancer.
-Ras proteins require membrane association in order to be biologically active. Membrane anchorage of Ras proteins in the inner leaf- let of the plasma membrane is an important factor in their signaling and oncogenic potential.
