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.

The answer is mutualism.
Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.
Answer:
mutalism
Explanation:
A. Stem cells are commonly found in the brain of adults.
B. Stem cells are flowing through our veins delivering oxygen to the other cells of your
body.
C. Stem cells are only found in prokaryotes.
D. Stem cells are unspecialized cells that have the potential to differentiate into a wide
variety of cell types.
Answer:
the answer to that one is D
Answer:
It might be A
Explanation:
It might be A because stem cells are usually found in brain, blood, bone marrow, muscle, skin, heart, and liver tissues.
Genetically altered crops are unable to reproduce.
Genetically altered crops produce less carbon dioxide.
Genetically altered crops require less pesticide.
Genetically altered crops are more delicious.
The correct answer is (C) Genetically modified crops requires less pesticide.
The genetically modified crops are designed in such a way that it requires less amount of pesticide. These plants contain the gene resistant for pest. These plants are often called as Bt plants. Almost 40% of the maize crops used in United States are genetically modified crops. All these are pest resistant and require very small amount of pesticide to kill some of the pest.
Answer:
The Great Pacific Garbage Patch is an environmental problem of the Pacific ocean water. It is accumulated with a trash of 10 meters deep non-degradable plastics. These plastic wastes can trap marine animals and contaminate the quality of water.
The Great Pacific Garbage Patch will be difficult to physical clean up because it actually lies in the international water, and no single nation is responsible for it's creation, also the filtering out of the plastic will effect the marine animals and diversity of marine phtoplanktons and zooplanktons.
Answer:
Sorry if I'm wrong but I think it's B
Explanation:
A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts or human activities such as specicide and human population planning.
