A muscle fiber will respond to a stimulus when that stimulus reaches the threshold level. These local classified potentials which are mainly related with external stimuli extent the axon preliminary segment and construct up to they manage to extent the threshold value. The bigger the stimulus the larger the depolarization or try to reach threshold.

Madagascar has suffered severe environmental degradation but still retains some of the most biodiversity on the planet.

some of the environmental issues in madagascar:
</span><span>Madagascar is among the world's poorest countries. As such, people's day-to-day survival is dependent upon natural resource use. Most Malagasy never have an option to become doctors, sports stars, factory workers, or secretaries; they must live off the land that surrounds them, making use of whatever resources they can find. Their poverty costs the country and the world through the loss of the island's endemic biodiversity. </span>
Answer:
In the stage of integration of the viral DNA into the host's cell, it is created the prophages. In this interaction, lysogenic conversion may occur, when a prophage induces a change in the phenotype of its host
Explanation:
The lysogenic cycle is a stage of reproduction of some viruses that infect bacteria, inserting their DNA into the bacterial cell. Together with the lytic cycle, they make up the two cycles of viral reproduction.
In the lytic cycle, the genetic material inserted synthesizes RNA that will form the capsids of the new phages and will eventually cause lysis and cell death. In the lysogenic cycle, viral DNA is integrated into the genome of the bacteria. The bacteria will live and reproduce, also replicating viral DNA in new bacteria without the virus manifesting itself. At the moment in which the DNA of the virus separates from the genome of the bacterium, the lytic cycle begins.
In the process of integrating the viral DNA into the bacterial genome, changes in the phenotype of the bacterium, generally associated with its pathogenicity, can occur, to increase the host's survival capabilities, this process is called lysogenic conversion. Even a non-pathogenic bacterium can permanently become pathogenic by lysogenic conversion.
