The release of an inorganic phosphate from the myosin molecule directly results in ________
zhuklara [117]

Answer:

power stroke

Explanation:

  • The process of muscle contraction requires several steps.
  • The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
  • However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
  • For the movement of myosin, it binds and releases actin and forms cross bridges.
  • Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
  • An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

A method used by horticulturalists when they rotate the use of fields—planting crops on a particular piece of land for a period
svetoff [14.1K]

Answer:

The correct answer will be- Crop rotation

Explanation:

When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.

Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.

The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".

Thus, crop rotation is the correct answer.
