Answer:
The answer is A.
Explanation:
To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.

Answer:
E. climax
Explanation:
Even though it is not something that is very common in nature, there are still certain exceptions where certain communities manage to reach a point of equilibrium. This basically is a community of small number of dominant prominent species that create a stable ecosystem. This state of equilibrium is known as climax community. This type of community appears when the web of biotic interactions between the organisms becomes so intricate that there is no possibility of other species to be admitted in it.

two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)
The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.
It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.
- The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
- The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.
