<h2>Region between 2 and 3</h2>
Explanation:
Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin
- During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
- Myosin thick filaments grab on to the actin filaments by forming cross bridges
- The thick filaments pull the thin filaments past them making the sarcomere shorter
- The region between points 2 and 3 includes the area of overlap between thin and thick filaments
Answer:
In 1964 2.6 bales per hectare while in 2008, 380 bushels per hectare.
Explanation:
in 1964, the average corn yield was 2.6 bales per hectare which is equals to 570 kg per hectare while in 2008, the average yield of corn was 380 bushels per hectare which is equals to 9655 kg per hectare. This increase in the productivity of corn crop is due to advancement of technology, high yielding seed varieties and reduces post harvest losses. The yield of 2008 is 17 times higher than 1964.
Exocytosis is a procedure by which a cell transports secretory items through the cytoplasm to the plasma film. Secretory items are bundled into transport vesicles. In exocytosis, the one that fuses with the membrane package is the cell membrane. The membrane is transported to the cell membrane and the water molecules are released into the extracellular environment.
