During weeks 17-20, quickening occurs, which is when the (d)<u> mother is able to feel the fetus move inside her womb.</u>

The period during which a fetus develops inside a woman's womb or uterus is known as pregnancy, it typically lasts about 40 weeks or just over 9 months in humans.

During the course of pregnancy, the fetus develops from being a single cell to a complete individual.

Quickening is the movement of the baby inside the mother’s womb at around 16-20 weeks of pregnancy. It assures the health and growth of the baby inside the uterus. A fetus that is growing well stimulates more quickening movements.

What are the two different results of a lack of calcium and a lack of atp?
liq [111]
<span>There are numerous proteins in muscle. The main two are thin actin filaments and thick myosin filaments. Thin filaments form a scaffold that thick filaments crawl up. There are many regulatory proteins such as troponin I, troponin C, and tropomyosin. There are also proteins that stabilize the cells and anchor the filaments to other cellular structures. A prime example of this is dystrophin. This protein is thought to stabilize the cell membrane during contraction and prevent it from breaking. Those who lack completely lack dystrophin have a disorder known as Duchene muscular dystrophy. This disease is characterized by muscle wasting begininng in at a young age and usually results in death by the mid 20s. The sarcomere is the repeating unit of skeletal muscle. 

Muscle cells contract by interactions of myosin heads on thick filament with actin monomers on thin filament. The myosin heads bind tightly to actin monomers until ATP binds to the myosin. This causes the release of the myosin head, which subsequently swings foward and associates with an actin monomer further up the thin filament. Hydrolysis and of ATP and the release of ADP and a phosphate allows the mysosin head to pull the thick filament up the thin filament. There are roughly 500 myosin heads on each thick filament and when they repeatedly move up the thin filament, the muscle contracts. There are many regulatory proteins of this contraction. For example, troponin I, troponin C, and tropomyosin form a regulatory switch that blocks myosin heads from binding to actin monomers until a nerve impulse stimulates an influx of calcium. This causes the switch to allow the myosin to bind to the actin and allows the muscle to contract. </span><span>
