Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.
Answer:
Innate immunity you are born with.
Acquired immunity you need to work on over time
Explanation:
Poison ivy for example. Come people are born immune to it, while others have to be around it a lot, (agonizingly so), and they will build up immunity to it's poison.
Answer:
cloning, Finn-Dorset, DNA, nucleus
Explanation:
So basically what they're doing here is they're taking the cytoplasm of a cell of the Scottish Blackface sheep (maybe a lamb?, whatever)/removing the nucleus inside that cell and instead inserting the nucleus of the Finn-Dorset sheep. Then they insert that "integrated" cell (so to speak) into a surrogate ewe so that the blastocyst can evolve and develop into Dolly (the lamb/sheep).
The process is cloning. The resulting offspring would be genetically identical to the Finn-Dorset (sheep/lamb) b/c the nucleus is coming from that sheep & the nucleus has the genetic material (DNA). Hope ya found this helpful :)
P.S. Oh yeah, and thanks for the fifty points (hopefully)
