what are the function of RNA polymerase ?
there are Three different types of RNA polymerases (RNAPs), which transcribe eukaryotic genes, such as RRNA genes are transcribed by RNA polymerase I.
mRNA, miRNA, snRNA, and snoRNA genes are mainly transcribed by RNA polymerase II, while tRNA and 5S rRNA genes are transcribed by RNA polymerase III.
short RNAs as well as the protein coding genes are both transcribed by RNA polymerase II.
A Separate type of RNA polymerases are present in chloroplasts and mitochondria, where they specifically transcribe the DNAs of those organelles.

Based on your hypothesis, which population(s) would be hurt if bears were added?
Answers
Answer:
The correct answer would be - plants, and small animals like moose, rodents, deer and others as bears are omnivorous animals.
Explanation:
In any forest ecosystem, mostly in the forest ecosystem, beers depend on various kinds of animals and plants for their nutrition and energy. They depend on plants that are rich in berries, fruits, and flesh roots. Beers also eat small animals such as rodents, fishes, and hoofed animals.
Therefore, an increase in the number of beers in any ecosystem will lead to a decrease in the population of these organisms and their population including plants.
What causes precipitation to fall to the Earth’s surface?
Answers
Answer:
What causes Precipitation to fall to the earth surface is when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.
If water is being extracted from an underground aquifer at a lower rate than precipitation is replenishing the aquifer, then the aquifer will eventually fill beyond
capacity.
True
False
Answers
Answer:
True
Explanation:
If precipitation occurs more frequently and it precipitates more than what is being extracted, it will eventually fill beyond capacity.
A student graphed distance versus time for an object that moves 14 m every 2 seconds. What is the slope of the ling on the graph. Please explain!
Answers
Answer:
A slope of 7, representing a speed 7 m/s.
Explanation:
Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:
[tex]speed = \frac{distance}{time}[/tex]
Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:
[tex]slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}[/tex]
Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.
Plants have low energy needs as compared to animals. Explain.
Answers
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

Dr. Kettlewell predicted that clean forests would have___________ colored moths, and polluted forests would have ____________ colored moths.
Moth type: Peppered moths.
Answers
Answer:
Dr. Kettlebell predicted that clean forests would have light peppered colored moths, and polluted forest would have dark peppered colored moths.
Explanation:
Kettlewell thought that if natural selection caused the change in moth population.
Dark moths resting on light trees were more likely to be eaten by birds then light moths.
Dr predicted the clean forest should have light-peppered and polluted forest have dark peppered.
Role of natural selection:At the time when Dr predicted the clean forest should have light-peppered and polluted forest have dark peppered.
So here the doctor think that the natural selection leads the change in the moth population. Also, the dark moth should be rested on the light trees that eaten by the birds as compared to the light moth.

horms the experiment three times, how much total water will the student need? Give your answerin
Answers
Answer:
550 milliliters of water is needed.
Explanation:
the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
