E. coli RNA polymerase is responsible for synthesizing the primary transcript for genes encoding enzymes involved in lactose metabolism.
These genes are located within the lac operon, which is 5,300 base pairs (bp) long. Given an average elongation rate of 70 nucleotides per second, we can determine how long it would take for the RNA polymerase to synthesize the primary transcript for the lacoperon.
To calculate the time required, we will divide the total length of the lac operon (5,300 bp) by the average elongation rate (70 nucleotides per second):
Time (seconds) = 5,300 bp / 70 nucleotides per second ≈ 75.71 seconds
Thus, it would take approximately 75.71 seconds for the E. coli RNA polymerase to synthesize the primary transcript for the lac operon at an average elongation rate of 70 nucleotides per second.

Radiocarbon dating can be used to date fossils in rocks to give an approximate age.
Explanation;
Radiocarbon dating is a technique for defining the age of an object involving organic material by using the properties of radiocarbon, a radioactive isotope of carbon.c material through using the properties of radiocarbon, a radioactive isotope of carbon. The development of radiocarbon dating has had an intense influence on archaeology

animal training is not a basic method used by ecologists to study the living world.
The practice of teaching animals particular behaviors to particular circumstances or stimuli is known as animal training. Training may be done for friendship, detection, protection, or enjoyment, among other things.
Depending on the training technique employed and the goal for which the animal is being trained, several types of training are given to animals. A seeing-eye dog, for instance, will be trained to accomplish a different objective than a wild animal in a circus.
There are organizations that certify animal trainers in different nations. They don't have any common objectives or specifications, and they don't stop someone from using the title or working with animals.
Therefore, animal training is not a basic method used by ecologists to study the living world.

a large area dominated by specific kinds of organisms
The phrase best describes a biome is large area dominated by specific kinds of organisms. The correct option is A.
A biome refers to a large geographical area on Earth that is characterized by distinct climate, vegetation, and animal life. It is defined by the dominant plant and animal species adapted to that particular environment. Each biome represents a unique ecosystem with specific abiotic (non-living) features, such as temperature, precipitation, soil type, and sunlight levels, which influence the types of organisms that can thrive in that region.
Thus, a biome can be described as a "large area dominated by specific kinds of organisms" due to the prevalence of certain species that have adapted to the environmental conditions prevalent in that biome.
