Question

1. which controversial aspect of genetic advancements involves the creation of genetically identical copies of an organism? a. gene editing b. genetic modification c. gene expression d. cloning 5. what is one of the main threats to endangered species? a. overpopulation of predators b. increased rainfall c. habitat destruction d. genetic diversity 6. what is the role of trna during translation? a. carries amino acids to the ribosome b. synthesizes mrna c. forms peptide bonds d. transcribes dna

Explanation:

• For question 4, cloning is the process of creating genetically identical copies of an organism. Gene - editing changes specific genes, genetic modification alters an organism's genetic material in general, and gene expression is about how genes are used to make proteins.
• For question 5, habitat destruction is a major threat to endangered species as it removes their living environment. Over - population of predators is not the main threat, increased rainfall is usually not a direct threat, and genetic diversity is beneficial, not a threat.
• For question 6, during translation, tRNA carries amino acids to the ribosome. mRNA is synthesized during transcription, peptide bonds are formed by the ribosome, and DNA is transcribed by RNA polymerase.

Answer:

1. d. Cloning
2. c. Habitat destruction
3. a. Carries amino acids to the ribosome
