The last one and the first one.
hope I could help you pls give this answer a hart thx
Explanation:
The answer is bioaccumulation. Bioaccumulation is when toxins build up in a food chain. The animals at the top of the food chain are affected most severely because the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.
To choose the strand the promoter acts to aim the RNA polymerase.
<h3>
What does RNA polymerase do?</h3>
RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.
Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

Answer:
evaporation:the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
condensation: his is when water vapour in the air cools down and turns back into liquid water.
