Hi there,
The answer to this question is
D. All of these
Changes in different temperature and acidity can change the function of a cell. Acidity and Temperatures are usually balanced for the cell function but one small change in one of them can throw off the cell of the pH levels.
Hope this is correct :)
Have a great day
Answer: Option D) 8 segments, with the 2 original strands on different segments
Explanation:
During polymerase chain reaction, a double stranded DNA (dsDNA) is selectively and repeatedly copied in the PCR machine.
In the first round, the single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
In the second round, the two dsDNA yields 4 segments before complementary nucleotides are synthesized to establish double helix.
In the third round, the four dsDNA yields 8 segments before complementary nucleotides are synthesized to establish double helix.
Thus, after 3 rounds, the two original strands are on the 8 different segments of copied DNA.
This answer is dandelion because i seen the answer to this in my book yesterday!
The moon is a satellite because it moves around Earth. Earth and the moon are called "natural" satellites. Satellites fly high in the sky, so they can see large areas of Earth at one time.
Earth is a satellite of the Sun and the Moon is a sub-satellite orbiting Earth.If the Moon somehow ended up outside Earth's Hill sphere, the Moon would orbit the Sun instead of the Earth just like all the other planets, asteroids, and comets.
Have a good day at school!
