Answer:
Myosin heads are attached to actin filaments
Explanation:
During the process of muscle contraction, myosin heads are attached to actin filaments. ATP is necessary for their release and for the muscle relaxation.
In rigor mortis, myosin heads continue binding with the active sites of actin proteins. This occurs because after death, there is no production of ATP and consequently, the muscle is unable to relax until further enzyme activity degrades the complex.

C) food accumulation
Phloem transports food from the leaves to other parts of the plant, and xylem tissue transports water and minerals absorbed by the roots. When phloem tissue is removed from a part of the stem, the food is not able to reach the lower part of the plant, causing the food to accumulate near the part of the plant where phloem was removed. This causes that portion to appear swollen.
