Answer:
Hydrogen Bonds
Explanation:
In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.
The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state
The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.
Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:
• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),
• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and
• Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)
Answer:
a: solution 2 is more diluted
Explanation:
It’s not a consumer what eats it is a primary consumer
F ( 18 ) = 1,50 * 18 + 12.50 = 27.00 + 12.50 = $39.50,
x - number of movies.
Answer: D ) $39.50; this is the amount Kelsey pays for 18 movies in 1 month
