Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state. 
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.

Biennial plants</h2>
Explanation:
This plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.
Since the Sweet William  plant did not flower last year when it was planted and this year also it did not bud till the spring. So, we can assume that these plant will need atleast two seasons to mature hence they are biennials. 
Depending on the life span, plants are classified as annuals (one season), biennials(two season) and perennials (more than two years).
