Question

1. how does natural selection influence the traits of a population?

a. it randomly changes traits over generations
b. it ensures all individuals survive equally
c. it favors individuals with advantageous traits for their environment
d. it eliminates all genetic variation

1. what is the function of rna polymerase during transcription?

a. translates mrna into proteins
b. synthesizes mrna from a dna template
c. forms peptide bonds during translation
d. synthesizes dna from an mrna template

1. which organisms serve as primary producers in ecosystems by converting solar energy into chemical energy?

a. plants, algae, and some bacteria
b. secondary consumers
c. decomposers
d. tertiary consumers

Explanation:

1. Question 35: Natural selection is the process by which organisms with favorable traits for their environment are more likely to survive and reproduce, passing on those traits. It is not random, does not ensure equal survival of all individuals, and does not eliminate all genetic variation.
2. Question 36: During transcription, RNA - polymerase synthesizes mRNA from a DNA template. Translating mRNA into proteins is the role of ribosomes, peptide - bond formation occurs during translation by ribosomes, and synthesizing DNA from an mRNA template is the function of reverse - transcriptase.
3. Question 37: Plants, algae, and some bacteria are primary producers as they convert solar energy into chemical energy through photosynthesis. Secondary consumers eat primary consumers, decomposers break down dead organic matter, and tertiary consumers eat secondary consumers.

Answer:

1. c. It favors individuals with advantageous traits for their environment
2. b. Synthesizes mRNA from a DNA template
3. a. Plants, algae, and some bacteria
