Answer:

Some factors that may cause a decrease in population size:

- a high mortality rate due to an infectious disease

- a low birth rate

- a high mortality rate due to interspecific competence  

- a high emigration rate

Explanation:

In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.

Transcription factors.

Explanation:

Transcription and translation are the two important process involved in the gene expression of a particular protein. Transcription is the formation of RNA and translation is the formation of proteins.

Transcription requires different enzymes and transcription factors. Transcription factors are important factors that regulates the expression of transcription and may increase or decrease the process of transcription. Here, the protein that binds with dioxin acts as the transcription factors as it regulates the gene expression.

Thus, the correct answer is option (3).
