Answer:
Option (1), (2) and (3).
Explanation:
Doppler effect may be defined as the change in wavelength due to the the movement of sound or radiowaves travels from the object. The frequency remains same if the distance between the receiver and sender's electromagnetic wave distance is same.
Doppler effect helps to learn about the universe behavior. Hubble used the Doppler effect to study the velocity of galaxy. The galaxy motion can be indicated by the wavelength and light.
Thus, the correct answer is option (1), (2) and (3).
An herbivore is an organism that only eats plants, a carnivore is an organism that only eats meat, an omnivore is an organism that eats both plants and meat, a decomposer (fungi and bacteria) break down dead matter and feed off of that, I don’t know the rest
Answer:
<h2>They provide a 3’ end for the DNA polymerase.</h2>
Explanation:
Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.
Polymerase chain reaction was invented by Kary Mullis in 1983.
Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.
