Answer:
The muscle fibers are pulled by the myosin and sarcomere together, resulting in the shortening of the fibres, but the sarcomere and myosin just move.
Explanation:
During muscle contraction, each sarcomere shortens, bringing the Z discs close together. There is no change in the width of the A band but both I bands and the H zone almost completely disappear. These changes are explained by actin and myosin filaments sliding past one another, so that the actin filaments move into A band and H zone. Muscle contraction thus results from an interaction between the actin and the mosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of the myosin to actin filaments that generate their movement relative to one another.
The phospholipids molecules are made up of two fatty acid chain and one glycerol compound which is attached to a phosphate group. Phospholipids are divided into two distinct regions, the head and the tail regions. The head region is polar while the tail region is non-polar.
The phosphate group which is located at the head region of the phospholipid molecules causes the glycero head to become hydrophillic [water loving]. Thus, the phosphate group impact polarity property on the head region of the phospholipid molecules.

Answer:
Explanation:As preschoolers' bodies develop over time, the areas in their brains that control movement continue to mature, thus enabling them to perform gross-motor skills such as running, jumping, throwing, climbing, kicking, skipping, and fine-motor skills such as stringing beads, drawing, and cutting with scissors.
Answer:The DNA of bacterial cells is found loose in the cytoplasm. It is called chromosomal DNA and is not contained within a nucleus.
