Solution:
The dna replication enzyme that most closely resembles rna polymerase is Primase. Which is the RNA that synthesizes RNA primers during DNA replication.
Thus this the required answer.
when a prairie dog spots a predator, it responds by giving an alarm call, but only when close relatives are near. this is an example of vocalization.
<h3>What do you mean by predator ?</h3>
The interaction between prey and a predator, where the energy flow occur called as predation and the organism feed on other organism called as predator and the food means the other organism is called as prey.
Predators can be carnivores and omnivores like Lions, tigers, sharks, and snakes, all are predators, it can fall prey to other large animals E.g. a snake is a predator to a mouse, but prey to a hawk.
Carnivorous predators directly kill and eat their prey like large animals such as the lion and tiger, they have their own mode of feeding.
Herbivore are plant eating animals like cows, buffaloes, goats, sheep, and deer; parasites are also under the category of predators which is a host dependent and live, get nutrients from host's body for survival and reproduction.

Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.
Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.
The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.
Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.
Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.
Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.
Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.
Some questions that can be answered by <em>Science</em> is:
-Is it possible to give nature and have shelter on other planets?
-What caused the global-warming?
-How can plane's fly?
