e-lub [12.9K]

Answer:

5;15

Explanation:

Local muscular strength and local muscular endurance are two important qualities of muscle functioning. The maximum weight a muscle can lift is indicated by Local muscular strength while the number of repetitions of particular task a muscle can perform without being exhausted is indicated by local muscular endurance. These both tasks are frequently used in our daily life

For example if you can pull 50 kg weight that would be your local muscle strength and if u can pull it 20 times that would be your local muscle endurance.

While performing the the intensity of resistance exercise during assessment if you pull the 50 kg weight less than 5 times it would be considered as local muscular strength and if you pull it greater than 15 times it would be considered as local muscular endurance.

Sort the examples into proper mechanisms of reproductive isolation.
vovangra [49]
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
