Answer:
A "chain reaction" is a reaction that promotes or spreads the reaction. PCR rapidly makes a bunch of copies of a specific DNA sample and can "promote" the increase the amount of DNA.
Explanation:
Except for researcher opinion. An opinion is an announcement portraying an individual conviction or felt that can't be tried (or has not been tried) and is unsupported by prove. A hypothesis is normally an expectation in light of some perception or proof. Speculations must be testable, and once tried, they can be upheld by confirm.
It would take one hour because if you are traveling at 120 km/h, you cover a distance of 120 km for every hour that passes. Since the distance from Dubai to Fujairah is 120 km and you are figuring out how much time it'd take to get from one place to another, you'd have to divide the distance (120 km) by the speed (120 km/h), which should give you an answer of 1 hour.
It’s a lunar eclipse for the fact that a solar eclipse the moon would be in front of the of the sun blocking out the sun making the earth dark in the spot where it is hitting in the celestial alignment that’s why it’s a lunar eclipse because moon is being blocked by the sun
Answer:
Predator prey
Explanation:
Animals that feed on other animals are called predators and the animals they eat are called prey. All predators have specific interactions with their prey as they are locked in an evolutionary "arms race". The prey will try to develop novel traits to survive as the predators will try to adapt to these. This is not a conscious process, but rather an evolutionary one, where prey individuals that have a survival advantage will survive and thus reproduce more.
The second image illustrates a predator-prey cycle where an increase in the prey numbers will lead to an increase in the predator numbers. This in turn will lead to a decrease in the prey number which in turn will also lead to a decrease in the predator's numbers.
The third image is a trophic or ecological pyramid in which X are the primary producers (ex. plants), Y are the animals that feed on these (prey) and Z are the predators that feed on Y. In general, top predators are not hunted and eaten by other species which is why they are at the top of the pyramid.
