Answer:
Monomers are joined by a covalent bond, and a water molecule is produced
First of all, pterophyta have neither seeds nor flowers in the first place.. Angiosperms are flowers and are the most diverse group of land plants so I doubt they would be losing its seeds... Lastly gymnosperms are a group of seed producing plants.. According to what I just wrote, what do you think the answer is??
<h2>Muscle contraction in cytoplasm </h2>
Explanation:
- Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
- ATP is basic to get ready myosin for official and to "revive" the myosin.
- When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
