Answer:

Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.

Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or w
nlexa [21]

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.

Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.  

Weak contraction

  • Potassium accumulates in the sarcoplasm.
  • Contracted lower sarcoplasm pH.
  • Begin contraction with muscle already 50%.
  • The circular arrangement of muscle fascicles.

Stronger contraction

  • Increase in muscle belly circumference.
  • A lesser proportion of motor neurons to muscle fibers.
  • Increased recruitment.
  • Increased stimulus frequency.
