in order to continually use the same area of land for agriculture, some farmers apply fertilizers to improve the level of nitrat
es in the soil. an alternative to this intensive use of fertilizer is to plow the roots of the leguminous plants back into the soil and leave the area unplanted for a season. why would a farmer use this alternative method and what would be the benefit of turning over the soil and leaving the old pant roots?
Ploughing and turning over the soil aerates the soil so the roots of plants are able to thrive well. Ploughing the roots of leguminous plants back to the soil returns nutritents and organic matter to the soil organically rather than using synthetic fertilisers which are potentially hazardous to the environment.
An idea map is a group chart that delineates how conceptual thoughts are connected. This sort of graphical perception device regularly utilizes circles or boxes to speak to ideas and associating lines to outline. The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown".
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.
Cloning will not lead to designer babies because clones are a complete copy of the person being cloned. The clone would need to be genetically modified to be considered designer
