Answer:
Depending on the stimulus, graded potentials can be depolarizing or hyperpolarizing. Action potentials always lead to depolarization of membrane and reversal of the membrane potential. Amplitude is proportional to the strength of the stimulus. ... Duration of graded potentials may be a few milliseconds to seconds.

Explanation:
The community may enter primary succession.
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
Like the harvested climax forest, secondary communities do not begin with the removal of soil and all biological life; other species, may be more suited to the altered conditions and begin to modify the area creating a new community.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

The answer is B
Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes
mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of protein synthesis.
Based on the translated information, tRNA then fetches amino acids from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.
