Answer:
During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.
Explanation:
<span>Bacteria is needed to convert nitrogen gas/ammonia into nitrates for "enhancing" the growth of plants.</span>
The answer is K-selected.
<span>The population size of K-selected species is fairly constant
in time, unlike the population size of r-selected species. r-selected species
are usually bellow carrying capacity and the population size is density
independent. On the contrary, K-selected species are usually near or at
carrying capacity and the population size is density dependent. It can be concluded that sperm whales have K-selected populations, since they </span><span>maintain their populations close to carrying capacity.</span>
